Abstract
Spiritual-led urbanism is being structured as a new paradigm in urban planning. Social inequality, polarization, moral poverty, and a high prevalence of psychiatric disease are only part of the manifestation of the lack of attention to the issue of spirituality in the production of space. Indeed, the challenge of the contemporary city is the emergence of the process of personalization of space production and capitalization resulting from the dominance of the speculative model and its confrontation with identity and semantic structure. In contrast to these challenges, the discussion of spirituality in recent decades by prominent Harvard scholars has emerged as an interdisciplinary paradigm, embedded in a powerful stream of critical communication planning theory and requiring context. Therefore, the present article analyzes the theoretical field of research related to the paradigm of spiritual development in the production of urban space. This article is based on a combination and is meta synthesis. The statistical population of the study consists of 55 ISI and scientific-research articles in the period 2008-2019. In order to collect and data analyze, methods such as systematic review and open coding have been used. In this context, comprehensive form for summarizing and extracting data from selected research was developed which issues concerning public profile and the theoretical framework of the research. The research findings are presented in two parts: structural and content. The first section examines the general features of selected research, the unreliability of studies on the impact of spirituality on urban space production, and the second section elaborates on the theoretical framework of research on spatial spirituality. production of spiritual-

Abstract
One of the most important and urgent issues of urban planning is the equitable distribution of facilities, services and accessibility of citizens at the urban level. Economic and commercial centers, including banks and financial institutions, are one of the most important economic sectors of cities and can be sustained. Social, economic, physical, and environmental impacts of neighborhoods. The purpose of this study was to investigate the extent of citizenschr('39') access to commercial land use in Ardebil neighborhoods. Therefore, the present study is applied in terms of purpose and descriptive-analytical in nature. The statistical population of the study is 44 localities of Ardabil city. Spatial statistics models, Hot Spot Analysis, and GIS software were used for data analysis. Finally, regression function in Idrisi Selva software was used to analyze the correlation between commercial user and population as well as to determine the relationship and correlation of this user with other service users. The results show that in Ardabil neighborhoods there is inequality in terms of overall business use. As a result, the neighborhoods have high commercial use weights and high concentrations of hot spots in optimum condition, including areas 3 and 5 from zone 2, zone 7 from zone 1 and zone 6 from zone 3. Also, commercial low weight blocks and low concentrations of hot spots, which include areas 8 and 11 from zone 2, area 11 from zone 3, are lower in urban sustainability. Finally, based on the results of the research, some suggestions have been made.

Abstract
Transportation and urban transportation policies are one of the most important tools which can be utilized for the qualitative and quantitative development of cities. Various factors can affect urban transportation systems including natural, economic, social, and cultural factors. the main objective of the current study is to evaluate and assess the resiliency of urban transportation networks in Ilam City, which is carried out using a descriptive-analytical and comparative method. The required information for the current study was obtained using library and field studies. The statistical population of the study included experts in urban management and crisis management, among which 40 participants were selected using convenience-based method and questionnaire was distributed among them. The analysis of the data was carried out using analytical hierarchy process (AHP) and integrated digital layers in Expert Choice and ArcGIS software applications. The results indicate that 49 percent of the transportation networks in Ilam City, which have a high level of resiliency based on the general criteria, are in high danger of flooding. Moreover, 72 percent of the traffic congestion points in Ilam City are located on streets with a high level of resiliency based on the general criteria. Among all the urban roads and streets in Ilam City, only 63 km has high levels of resiliency and these are mostly the main streets of Ilam City. The final results of the study show that improving the urban transportation system of Ilam City not only involves the structural issues of the roads, but it also involves a large number of administrative issues. Therefore, first we have to identify dangerous areas and then try to take the necessary measures through appropriate management decision making in order to improve these urban transportation networks.

Abstract
Awareness of the status of vegetation, land use change and surface temperature in each region, and the timing and location of their changes over time are important for micro and macro planning. In order to make optimal use of land, knowledge of land use changes is necessary, which is usually possible by detecting and predicting land use changes. Measuring the role of researches and researchers has been instrumental in the study of natural resources, especially vegetation, surface temperature and user variations in each location, as well as the availability of information for different times for valuable studies. In this study, ETM and OLI were used to study the process of land use change, vegetation cover, surface temperature, and hazards caused by them in perennial seasons. The results show that the area of use changes over the period 2000-2010 has decreased the area of use of the developed area, agricultural and growing gardens and the area of land and rangelands. Artificial vegetation has risen in aggregate and rangeland lands are showing a decreasing trend. Due to the importance of vegetation and its role in reducing the temperature of the earth's surface, the trend has been decreasing in regions with intensive vegetation and high temperature. Also, in the period from 2010 to 2017, the range was further increased and the city's growth continued sporadically, causing environmental changes and rising temperatures in the city. The change in the city's increased range has increased environmental risks, including the loss of good agricultural land and the increase in the temperature of the city. Due to the fact that most agricultural land is located in the vicinity of the city under cultivation of saffron, which in the warm seasons does not have surface coatings, changes in the type of cultivation can also affect the temperature of the earth.

Abstract
In this study, in order to study the base temperature (minimum temperature for plant growth) at the degree of growth day (GDD), which is one of the important parameters in calculating the degree of growth day, first, the data required for the 2009-2017 statistical period of wheat production at the station Sararood was taken from the station. Then, after sorting and separating growth different stages, using four methods of calculating the base temperature (1 - minimum standard deviation SDgdd day, 2 - minimum standard deviation SDAY days, 3 - regression coefficient per day CRday, 4 - CV coefficient of variation) was the most suitable method for calculating the base temperature of growth in different stages of planting to wheat harvesting. The results showed that the most suitable method is the minimum standard deviation in GDD, which The base temperature was obtained from germination to full reach for different growth stages, 5/8, 0/38, 1/8, 2/6, 0/63, 2, 3/7, 9/7, 8/6, 11 degrees Celsius. By comparing different methods of calculating GDD, the most appropriate of method was the general method of calculating the degree of growth day due to the most of similarity to the station data. The degree of growth day in different stages was calculated based on their base temperature and the results showed that the calculation of the base temperature at each stage of the growth of the wheat was very accurate for GDD calculation and a precise estimate of GDD was obtained.

Abstract
In this research, we are trying to determine the “beginning time” as well as the “end” of the climatic seasons; and we will focus on identifying the displacement of these dates, which is influenced by the “climate changes” and “descriptionAbstract
The purpose of this study is to investigate possible changes and displacements in Iran's climatic seasons due to climate change. To do this, temperature, relative humidity, water vapor, wind and cloud data for 36 stations were received from the Meteorological Agency over 40 years. The data were divided into two 20-year series to allow comparison. Daily temperature data for each clustering time series were determined, then by considering 7-day sequences, the beginning and end of the seasons. The designated times were tested using the Rayman model. The results of comparing the seasons in the two time series indicated that in all stations, changes in climatic seasons occurred from Insignificant to significant. Climatic seasons in Iran do not correspond to calendar seasons, and climate change, especially temperature changes in recent decades, has caused the seasons to shift and shorten and lengthen. Although the beginning and end of the seasons do not generally correspond to their calendar dates, most of the days of these seasons occur in its calendar periods. The changes that have taken place have not only affected the length of the seasons, and these shifts have also changed the quality of the natural seasons.
Keywords: Climate change, natural seasons, cluster analysis, Rayman model of the qualitative conditions” created in them, compared to the past climatic periods. “Meteorological Organization” data has been used in this research. Forty years of received data, was divided into two groups of 20. Applying SPSS, each group was divided into four stages representing each seasons. From these stages, the beginning time and the end of seasons were determined and the accuracy of the obtained dates was controlled with the comfort indicators of the Rayman model. The results of the comparison of seasons in two time series indicated that, the changes occurred in natural seasons from an almost non-existent one in all stations. Climatic seasons in Iran are not compatible with the summer season and climate change, especially the change in temperature in recent decades, has caused changes and shortening of seasons. Most of the days in these seasons occur during its monthly periods, although the beginning and end of the seasons generally do not match their calendar dates. Changes have not only affected the duration of the season, and these changes have also led to a change in the natural quality of the season.

Abstract
In this study, the actions and interactions between the city and the border were studied and explained. This research is applied in terms of purpose and in terms of descriptive-analytical method in library and field method. Data were collected through questionnaires and interviews. The statistical population consists of one percent of the population of border towns of Zahedan, Mirjaveh, Dost Mohammad, Khash and Saravan(N=8092). Using Cochran formula, 367 people were selected as the sample. Data were analyzed using Structured Analytical Model (SOWT-ANP). Findings and results showed.the most important effective factor on city-boundary relations is social factors with a mean of 3.55 and among weaknesses, Most affected were social weaknesses with a mean of 3.63 and among the opportunities examined, economic and managerial factors with a mean of 3.53 and Finally, they have the most impact on all types of threats, injuries and social threats with an average of 3.75. Also, the use of the method(F.ANP)in this study showed that the highest weight related to the threat factor was "management", which gained 7.9% of the final weight and took the first place. "Establishing economic, political and environmental security to deal with crises, attacks and ... (ST2)" is the most desirable strategy of deciding on the issue of zero value. And the strategy of "non-cooperation and interruption of cross-border relations with neighbors (WT1)" has been identified by experts as the worst strategy in this regard. Therefore, it can be said that among the factors (SWOT) "threats and challenges" in security and management dimensions is the most influential factor And the real gap between the "opportunities" is the key to improving the relationships between cities and territories. Also, from the standpoint of sustainable development management (institutional and structural) factors with the highest degree of importance and social, economic and environmental factors are ranked next.

Explaining the relationship between resilience to natural disasters is in fact how social, economic, institutional and physical capacities affect the increase of resilience in societies. Accordingly, the purpose of this study is to investigate the resilience of Shirvan city in the face of earthquakes in which the research method is descriptive-analytical and the statistical population includes experts in the field of urban resilience for this group of 30 people. First, the indicators evaluated to assess the resilience of Shirvan city in the face of earthquake hazards using the ANP model, which were questioned by experts and elites, were 25 indicators in 4 physical, institutional, cultural, social and economic criteria. Paired comparisons were performed. Findings showed that the rate of resilience in Shirvan is low in 65.4% of the city and high in only 19.2% of the city. In other words, in 17 neighborhoods out of 26 neighborhoods of Shirvan city, the rate of resilience in the face of earthquake hazards is low and only in 5 neighborhoods of the city the rate of resilience is high. Therefore, the final results of resilience in Shirvan are 19.2% of the upper city, 15.4% of the average city and 65.4% of the lower city. In general, the results indicate that the resilience of Shirvan is in an unfavorable and unfavorable situation and the rate of resilience in this city is low in the face of earthquake hazards.

Abstract
Based on the notions and assumptions of the discourse of “new urban regionalism”, there is a close relationship between the "spatial morphological structure" and the "spatial division of labor" in a megalopolis region, and solving existing problems in one without another is not possible, because they can either act in the direction of positive reinforcement and support, or in order to weaken and become an obstacle to each other; therefore, what is meant by the problem of achieving equilibrium and integration in the spatial structure and the functional system in a megalopolis region, will not be possible without recognizing the nature and relationship between these two. The reviews done the research shows that "spatial morphological structure" and "spatial division of labor" in Tehran's megalopolis region during the recent decades has not been able to support each other and significantly reduce the spatial non-equilibrium in the region. Therefore, according to the results obtained in the framework of this study, the "spatial morphological structure" and "spatial division of labor" in Tehran's megalopolis region during the recent decades (1345-1390), has been accompanied by a significant reduction in the spatial non-equilibrium in the region, though, the trend of transformations is on the move. One of the strategic implications of this is that the future issue of the Tehran's megalopolis region is to be more focused on the peripheral population poles and the improvement of the level of performance of the city itself in order to accept transnational functions and create alternatives and opportunities for roles and the tasks that will be assigned to them in the future. Just as in the prior years the industry sector has gradually shifted to the service sector, in the future it also seems necessary to give up the services sector to itself periphery and oppose the acceptance of the fourth sector of the global economy (such as; Information, communication and cultural economy).

Abstract
Examining the effects of climate change on the oak spatial distribution, as the main species of Zagros forests and its ecological and economic values is of significant importance. Here, we used species distribution models for simulating current climatic suitability of oak and its potential changes in 2050 and 2070. For this purpose, five regression-based and machine learning approaches, four climatic variables related to temperature and precipitation and two optimistic (RCP 2.6) and pessimistic (RCP 8.5) greenhouse-gas scenarios were used. The results of measuring the accuracy of models by AUC indicated the good performance of all algorithms and Random Forest achieved the highest accuracy (AUC = 0.95) among other methods. The results showed that in both time periods and under both scenarios, changes will occur in oak spatial distribution and the most severe one would be a 42.9 percent loss in the oak climatic suitability in 2070 under pessimistic scenario (RCP 8.5).

Abstract
The attachment to the place is the emotional relationship of the individual to the place, which is rooted in the person's past qualities and experiences that the place should be able to meet the needs and expectations of the individual, and also the place must meet the capacity to meet those needs and expectations. The attachment to the location is based on the cognitive, emotional, and functional interaction between individuals, groups, and physical-social location over time. The purpose of this study was to use the meta-analysis method to analyze the results of research on attachment to the place. In order to perform a meta-analysis, 75 researches were conducted in this regard. Among the 18 studies conducted during the years 2006-2019, in the field of attachment to the place were selected. In the first step, the evaluation of selected research, homogeneous assumptions and publication error was studied; accordingly, the findings indicated the heterogeneity of the size of the effect and the non-dominance of the published studies. In the second step, the coefficient of effect size was evaluated using the second version of CMA software. The results showed that the size of the effect or coefficient of influence of the identified factors is 0/376, which is evaluated according to the Cohen's interpretation system. Overall, the results indicate that the identified factors have a moderate effect on attachment to the location.

Abstract
According to statistics, about 300,000 disabled people live in Iran. There are about 25,738 disabled people in Ardabil province. This calls for attention to macro-planning for the disabled. This planning involves cognitive and spatial analysis of the status of the disabled people in different parts of the country. The purpose of this study was to analyze more precisely the situation of the spatial dispersion of the disabled and their relationship with different regions of the cities of Ardabil to address further the problems of accessing urban services and creating better living conditions for people with disabilities. In the present study, indicators such as age, gender, the status of residence, type and severity of disability, marital status, education and employment were analyzed using spatial statistics analysis. Also, the geographically weighted regression (GWR) model has been used to measure the relationship between the extent of development and disability. Findings of the research show that there is no relationship between the extent of development and disability in Ardabil province. The number of disabled males is higher than that of the disabled females in all cities. Disabled people in Ardabil province are young and 91.55% of them are illiterate and close to 96.74% of them are facing unemployment problems. In almost all cities of Ardabil province (73.98), there are severe to very severe disabilities and there is no specific order among different cities in the province of Ardabil regarding the type of disability, and various disabilities have been dispersed in the province.

Abstract
The national strength of algebraic aggregation is a large number of positive and negative factors that are composed of numerous sources and resources. One of the important sources of national power in the world today and in the post-Cold War period is economic power, which is itself the bedrock of other superstructures, such as political, military, and so on. This research uses descriptive-analytical method and using library resources and field research to answer this question. What are the most important variables and indicators that shape economic power of countries? The findings of the research by examining library documents show that the four main components of economic power including infrastructure, production exchange, production level and financial resources can affect economic power. Meanwhile, 61 variables related to quadruple components were identified. Then, by using the Likert spectrum questionnaire, internal knowledge was measured to measure the importance of each of these variables. Accordingly, economic infrastructure, high-tech exports, food imports and international currency reserves were of high importance. On the other hand, variables such as the share of the poor in the consumption of national income, economic competition, foreign ownership, and commercial costs of violent crimes were of minor importance. Finally, it can be argued that countries have an obligation to take into account the factors and variables in the economic dimension to achieve their national interests and interests.

Abstract
Study of resources changes in previous years could be useful in the planning and optimal using of resources to control inappropriate changes. Because land use changes occur on large-scale, remote sensing technique is a useful and valuable tool for monitoring the changes. The aim of this research is land cover changes detection in a period of 32 years in Pishva town with using remote sensing technique .First TM, ETM and OLI images for the years 1986, 2002 and 2018 were collected respectively and after geometric and radiometric corrections, images were classified by using maximum likelihood classification methods. Kappa and overall indexes were used to calculate classification accuracy. Results showed in past 32 years, bare land and irrigated land have decreased while residential and greenhouse areas have increased. Classification accuracy showed that OLI, ETM and TM sensors have high accuracy respectively with kappa 0.96, 0.80 and 0.76 and also overall indexes of 97.56, 86.54 and 86 percent. Based on results, in the first period (1986-2002) 27.6%, in the second period (2002-2018) 29.60% and in the third period (1986-2018) 31.8% of area land cover have been changed. Results showed land cover changes in the area is related to climate changes like low precipitation, drought and social condition like population and food need increasing and economic condition like high production and efficiency.

Abstract
Air pollution is one of the major problems in large cities, which can be harmful to human health and the environment. Isfahan is one of the most polluted cities in Iran.
Its geographic location and low wind speed, industrial activities, transportation, agriculture, and other human activities have created critical air pollution conditions for the city. Nitrogen dioxide is an important pollutant of air pollution, which is monitored using ground stations and satellite measurements. In this paper, daily data of nitrogen dioxide from Ozone Monitoring Instrument (OMI) satellite sensor, wind and surface temperature of Isfahan Meteorological Station data were used between October 2004 and May 2016. The average amount of nitrogen dioxide in the measured range is .The highest amount of nitrogen dioxide ( ) was observed in December and the lowest ( ) was observed in July. The standard deviation of the winter season ( ) is higher than the summer season ( ). The correlation coefficient of nitrogen dioxide with wind and temperature was -0.41 and -0.54, respectively, which indicates the higher importance of temperature in nitrogen dioxide changes. After the formation of the time series, the average monthly nitrogen dioxide content was determined using spectral analysis of least squares of statistically meaningful peaks corresponding periods. These statistically meaningful peaks corresponding periods have been eliminated from the mean monthly nitrogen dioxide time series, and with the linear fit on the residual time series, the trend has been calculated. The nitrogen dioxide trend for Isfahan is per year with 95% confidence.

Abstract
Many contemporary urban environments are not self-sufficient with the physical and mental characteristics of the residents. Proper and purposeful design of urban environments can reduce the risks to health. The rivers of urban valleys and their open spaces are our natural and national wealth and heritage. Their value in urban plans remains unknown. In this study, in order to organize spatial space along urban rivers with a health promotion approach to achieve suitable environmental conditions for the survival of Darkeh River in Tehran (between the Modiriat bridge and Hemmat highway) and improving the quality of the surrounding environment. The research method was descriptive-analytical with survey technique. Using SPSS and LISREL8.80 software, the descriptive data of the questionnaire were analyzed. Internal and external environmental factors have been identified through field interviews from residents of three neighborhoods of IranZamin, DehVanak and the scope of the project using SWOT method. Using the Pearson continuity test and the SEM continuity diagram, it was found that there are four direct components of river flow organization (safety, continuity, vitality, flexibility) and improving the health of citizens in these three neighborhoods. At the end of the conceptual model, based on the effect of independent variables of organizing river-valleys on the dependent variables of citizenschr('39') health, it was presented and drawn and the fit of the conceptual model was confirmed using standard values of T test. In the end, based on the current situation and analyzes, 11 strategies and 39 design strategies have been presented.
