Abstract
Undoubtedly, the development of tourism in any region requires a precise identification of the area and the provision of facilities and services needed by tourists, which is essential for the purpose of planning at all levels in order to achieve the successful development of tourism. This research deals with the pathology of service provision and prioritization of tourist destinations in terms of tourism potential in Zanjan province. The research was a combination of qualitative and quantitative, which was the method of collecting information in the form of interviews and questionnaires. In order to analyze the interviews from MaxQuda, the hierarchical analysis model was used to evaluate the criteria and the geographic model was used for the geographical distribution of tourist destinations. According to the findings of the research, Zanjan province, despite having suitable capacities for tourism, suffers from many problems such as lack of facilities, instability in policies to improve the quality of tourism services, and lack of management and planning in tourism development, and has not yet enjoyed proper progress in this field. The low general level of services and inconsistency in planning and different views on tourism are the two main problems of the tourism services sector in Zanjan province. But according to the geographical distribution, tourist destinations: Soltanieh dome, gen chimneys, Angoran mine, Oljaito ecotourism resort, Soltanieh ecotourist resort, boutique hotel, Zulfaqari mansion, El Daghi, Seyed Mohammad bridge, Zanjan Jame Mosque, Khedevi house, colorful mountains in the first cluster This means that the tourist destinations in question are surrounded by high capabilities and more population, which should be placed as priority areas in the planning and development of services.

Abstract
In this research, the most important synoptic patterns of widespread snowfall in the eastern half of Iran have been investigated. For this purpose, the current weather code data and snow depth of synoptic stations in the eastern half of the country during the statistical period of 1371-1400, for the months of October to March, were received from the country's meteorological organization. In order to investigate widespread snowfall, the days when more than 70% of the studied area saw snowfall at the same time were extracted as a widespread day. In order to perform synoptic-dynamic analysis of widespread snowfall in the eastern half of Iran, the classification method using cluster analysis was used and the maps of the representative days including atmospheric temperature, moisture flux, geopotential height, vorticity, front formation, jet stream, omega index and orbital and meridian wind data were drawn. Trend analysis was also performed using the Mann-Kendall test. The results showed that 3 patterns justify the snow cover in the studied area. These patterns are: high pressure in Siberia and central Europe-low pressure in eastern Iran, high pressure in western Iran-low pressure in Sudan, high pressure in central Europe-low pressure in eastern Iran and Afghanistan. In all the patterns in the middle of the atmosphere, the intensification of the meridian currents of the western winds along with the formation of high pressure and low-pressure centers has caused blocking in the path of the western currents and has provided the conditions for the ascent of the air. The concentration of the negative omega field and the relative positive advection, along with the location of the northeastern region of Iran in the left half of the outlet of the Subtropical Jet, have caused severe instabilities and widespread snowfall in the region. Also, the results showed that despite the absence of a trend in the number of snow days in the northeast of Iran, the number of snow days has decreased over time.

Abstract
| There are various indicators to monitor and management of agricultural water resources in arid and semi-arid countries including Iran, some of which can be extracted directly in situ, and some can be retrieved using remote sensing technology and satellite images. Aim of this study is to propose the most appropriate and efficient indicators of agricultural water resource management for achieving maximum production and maximum water efficiency using remote sensing technology, therefore, Crop Water Stress Index (CWSI) and Surface Energy Balance Algorithm (SEBAL) were used to estimate Evapotranspiration (ET). In the first step, ET rate was calculated using SEBAL algorithm for six Landsat 8 satellite images related to the wheat growth period. Then, zoning of this index was done in the range of zero to one, in four categories of very low, low, medium and high, which respectively indicate the lowest to the highest amount of ET. In next step, CWSI was calculated based on Idso equation, and its results show different changes both in cold season and in warm months. Comparison of ET and CWSI shows a significant relationship between these two indices in warm months, while in cold months, no significant relationship can be seen. These findings along with the established relationship between ET and CWSI can inform water management strategies in arid environments for sustainable crop production. |

Abstract
Trees can record long-term effects of climate variables. Using dendroclimatology knowledge, we can reconstruct such variables especially for areas which have short-term climatic data. For this purpose, we reconstructed the temperature degree of the warm months (May-September) through annual rings width of Quercus persica and regression analysis of data obtained from stations on Dena region. With this goal in mind, three growth heights were selected in Dena Forests and 52 growth samples from 26 bases were extracted and their growth rings width were measured with LINTAB5 with an accuracy of 0.01 mm. After cross dating stage, to eliminate non-climate effects, May to September temperature average and tree rings time series were standardized. The Residual Chronology (RES) calculated by ARSTAN was calibrated with temperature degree of the period 1882-2011 and its positive and significant correlation with the width of growth rings was confirmed. Based on the relations between the calculated chronology and joint statistical temperature degree data, the reconstruction of temperature degree of the warm seasons for over a century was performed and it was found that in the last three decades, region's average temperature of May to September had an increase in comparison to the average of the previous century.

Abstract
Estimating and predicting precipitation and achieving its runoff play an important role to correct management and exploitation of basins, management of dams and reservoirs, minimizing the flood damages and droughts, and water resource management, so they are considered by hydrologists. The appropriate performance of intelligent models leads researchers to use them for predicting hydrological phenomena more and more. Therefore, in this study, the Gene Expression Programming (GEP) and Support Vector Regression (SVR) models were used to model monthly precipitation of Nahavand City. In this study, precipitation, temperature, and relative humidity data were used in a 32-year period (from 1983 to 2014). The results showed that the same and good performance of both models (R2= 0.92), but according to different evaluation criteria, GEP model showed a little better performance (RMSE= 0.0478 and 0.0486), while the running GEP model is so easier than the SVM model. Totally, it can be said that GEP model had been suitable for modeling monthly precipitation of Varayeneh station in Nahavand City. Finally, the monthly precipitation was predicted the GEP which showed a decrease in precipitation in compared with previous months.

Abstract
Religious tourism, as one of the ways of development, cultural exchange and social interaction between nations can have many benefits for any society today. Enjoying indigenous cultures and local religious ethics is an important factor in attracting tourists. The city of Khorramabad has special religious ethics, such as the celebration of gellmalli in the Ashura Day and the chehell manbarr in Tasoa day, which can have a profound effect on this. Therefore, the present article, using descriptive-analytical method, and questionnaire, interview and observation tools, and with the assumption that indigenous religious-cultural ethics increase the value and importance of tourist attractions at the destination, has attempted to survey the role of chehell manbarr in tourism development of Khorramabad city. The results of one sample T-test at the significant level of 0.000 indicate the impact of all three indicators of abilities and potentials in the chehell manbarr, visual beauties and custodians of urban organizations such as Culture and Islamic Guidance, Municipalities and other related organizations Is above average; Also according to the results of one-way analysis of variance at the error level below 0.05% , it is vary the effect of the index of abilities and potentials in the chehell manbarr ceremonies, and the effect of metropolitan organizations such as culture and Islamic guidance and municipality according to the educational levels of the respondents. However, the results of one-way analysis of variance for the extent of visual beauties on tourism inclination are similar at the educational level of the respondents. The results of regression analysis at the significant level of 99% show that all three variables of keeping of urban organizations such as culture and Islamic guidance during the chehell manbarr ceremonies, the abilities and potentials in the chehell manbarr ceremonies and the creation of visual beauties have a direct and significant effect on the tendency to Tourism and motivation for future trips.

Abstract
Land surveying to increase crop production and productivity is nowadays considered as one of the alternative approaches in agricultural development and the need to address this issue especially in rural areas where their income is highly dependent on agriculture is of great importance. Is high. Agricultural development is one of the priorities of agricultural planning and requires such development to identify the effective factors that govern it. The purpose of this study was to evaluate and evaluate the environmental capabilities of olive cultivation in Tarom city and to analyze the location of its producing rural areas. Hence, from altitude, slope and slope status as terrestrial parameters and three climate parameters as relative rainfall, temperature and relative humidity data from 11 meteorological, synoptic and rain gauge stations with appropriate statistical period (1375-1395) and A common time base was used for climatic zoning. The results showed that Tarom city is in good condition for olive cultivation, 21.2% of the total area of the study area is suitable for olive cultivation, most of which is located in the middle districts of the city. Located in olive-growing lands, these areas produce 74.8 percent of the olive in Tarom, due to its olive-growing potential.

Abstract
In recent years, attention has been paid to climate change, which could be the result of economic, social, and financial losses associated with extreme weather events. The purpose of this study is to investigate the variation of extreme temperature and precipitation in Kurdistan province. For this purpose, daily rainfall data, minimum temperature and maximum temperature of 6 stations were used during the statistical period (1990-1990). And their changes during the period (2041-2060) using the universal HadGEM2 model under two scenarios RCP2.6 and RCP8.5 and the LARS-WG6 statistical downscaling were investigated. In order to study the trend of climatic extreme indexes, rainfall and temperature indices were analyzed using RClimdex software. The results showed that during the period (2016-1990), hot extreme indicators have a positive and incremental trend. This trend is significant for the "number of summer days" and "maximum monthly of maximum daily temperature" indicators. This is while the cold extreme indexes had a decreasing and negative trend. This trend was significant only for the "cold days" index. Extreme precipitation in Kurdistan province has a negative trend in most stations. ،this trend is significant at most stations, that indicates a reduction in the severity, duration and frequency of precipitation during the study period. The results of the climate change outlook also indicate that the temperature will increase over the next period and rainfall will decrease.

Abstract
Knowledge of rangeland vegetation characteristics as well as factors affecting it in environmental planning, land management and sustainable development is very important. However, regional and up-to-date maps of pasture vegetation cover are not always available. In this study, in order to plot the vegetation cover percentage of the rangelands and monitor its changes in drought and wet periods, NDVI products of MODIS sensor during the years from 2000 to 2017 with a spatial resolution of 250 m and a 16-day time resolution, and The SPI drought index were used. The study area is the part of the rangelands located in the Southern province of Yazd. In 2013, in order to provide ground truth data, a field work was done to take the sampling rate of vegetation from the rangeland level in the study area. According to the results, the NDVI index has a good ability to map vegetation cover, so the coefficient of determination (R2) between this index and the sample points was 0.71. Based on the results, the average vegetation cover of the studied area was 11.3% during the years 2000 to 2017. The highest and lowest amount of vegetation cover in the study area was in 2000 and 2002, with moderate mild conditions and very severe drought, respectively (14.6% and 9.2% respectively). The most important factors influencing the vegetation cover in the study area are rainfall and drought periods, so that the coefficient of determination (R2) between the SPI drought index and the average vegetation percentage was 0.85. In general, based on the results there is a high potential for assessing and monitoring rangeland vegetation changes using satellite data and remote sensing technique.

Abstract
Citizenship is a set of rights and duties a citizen enjoys because of his or her country of residence. Municipal law is a set of laws, rules and regulations that govern the interconnection of citizens and city departments in local and urban affairs, and explain the duties of overseers of councils, municipalities, and other city institutions; And planners 'and architects' awareness of the rights of citizens is one of the influential components in the process of urban architecture planning which is discussed in this article. Contemporary theories of urban law have led to a new military framework based on the concept of "right to the city" about urban life; if general framework can be understood in the context of the general concept of "right to the city", the following formulation from the Eiken set of laws on the concept of citizenship. It provided the architectural and urban planning rights: 1. the right to allocate; 2. the right to participate; 3. the right to centralization; Right of residence The right to habitation; 6. The right to individualization in socialization. Finally, the relationship between these components and their characteristics with the degree of their relevance and relationship with architectural and urban rights is presented.
