Saman Alimoradi, Asadollah : Khoorani, Yahya Esmaeilpoor,
Volume 17, Issue 44 (3-2017)
Abstract

The aim of this study is to retrieve land surface temperature (LST), air temperature (AT) and precipitation and to study their relationship with vegetation in rang lands of Karun watershed of Khuzestan province. For this purpose, land surface temperature (LST) and NDVI was drived from NOAA-AVHRR for maximum amount of greenness (April) for a period of 27 years. In order to extract LST, Price algorithm was used. Also air temperature and precipitation were interpolated for selected weather stations using IDW method. Spatial correlation outcomes (on 0.05) between NDVI with LST and air temperature show a reversed relation. This spatial relation is stronger for LST, so that this coefficient is often upper than 0.6, while seldom is 0.4 for air temperature and precipitation. Spatial regression models show that 62 percent of NDVI changes is determined by LST (R2=0.62) and air temperature and precipitation determine very limited amount of NDVI dynamics.

Mohammad Hasan Yazdani, Afshar Saidain ,
Volume 17, Issue 44 (3-2017)
Abstract

At the moment with regard to geopolitical and geostrategic situation of Iran, the existence of countless underground resources and the formation of ideological state, unfortunately, in urban areas of the country, especially in Ardabil ,because of its proximity to the border of northern and northwestern borders with knowledge of this particular situation, economic and infrastructural projects, Infrastructures and installations have been made without observing and interference of considerations and defense and security arrangements and have become a bare and significant available target for enemy and invading countries. This research aimed to study the vulnerability of Infrastructures Ardabil in terms of passive defense and application - development approach in a descriptive and analytical way using 18 effective indicators in form of 5 components of "Lifeline", "crisis management Centers", "military and police centers", "Urban equipment" and "support centers" in three priorities of strategic, psychological and support destruction. Information gathered in the Super Decision software (network analysis) are weighted, then mapped in GIS environment. The results of the studies show that there are six major hazardous zones under crisis conditions and are prone to injury in the Ardabil that the most important of them are the northeast output of Ardabil (Jahad field leading to Astara gate), the southwest of Ardabil (Sarein station leading to the Basij field toward the Sham Asbi village) and finally the north and northwestern parts of Ardabil (Vahdat square), with the sum of (17% of the total land area of the city) have included the highest vulnerability, due to the poor conditions of the physical characteristics and focus on management, corporate, military and state entities in this regions of the Ardabil city.

Volume 17, Issue 44 (3-2017)
Abstract
Among the various processes that destroy lands, soil erosion is a complex and hazardous environmental process that constitutes a serious threat to preservation of soil and water resources in Iran and has inflicted its negative effects on the vital ecosystem with the intensified utilization of nature by human beings. The present descriptive and analytic research employed the PSIAC model to study erosion and compare it with other empirical methods and models by investigating the effects of nine important and influential factors in soil erosion and sediment production in various parts of the Sefidrood Basin through giving intra-layer numerical scores to them. Erosion and landform zoning maps and also zoning maps for the nine factors were then extracted. Results indicated that 77 percent of the lands in the plain landforms faced very little erosion and 23 percent little erosion, 14 percent of the lands in the mountainside landforms were exposed to very high erosion rates, 55 percent with high erosion rates, and 31 percent with average and low erosion rates, and 17 percent of the lands in the mountain landforms experienced very high erosion rates, 58 percent high erosion rates, and 25 percent average erosion rates. In other words, the rates of erosion changed from low in the plain landforms to very high in the mountain landforms. This implies that pastures and natural resources are confronted with numerous problems. In general, considering the study carried out on the nine influential factors in the soil erosion model (the PSIAC model), we notice that the mountainside and mountainous regions are more sensitive to erosion and influential factors in erosion are more active in these regions.

Amin Mahmodi Azar, Rahim Hashempour, Sid Momen Fovad Marashi,
Volume 17, Issue 45 (8-2017)
Abstract
In recent decates, the subject of quality of living in city and the satisfaction of citizens from their environments has attarced the views the most of researchers and international institutes around the world. Because of its importance, UN to publish a report annually in which different cities around the world ranked and compared through the quality of life. Quality of living talk about different indices and one of its important indices is access to the city services which in turns would decrease some of the city problems such as slums and irregular construction, land speculation and etc. This research tries to analysis the city quality of living according to the standards of services access in cities. So, quality of service access was analysed in objective and subjective sections in old zone of Urmia. The research method is descriptive-analytic and we use questioner, different models such as AHP and network analysis and fuzzy techniques, Pierson coefficient for our study. Results show that satisfaction of city-service access has a very meaningful statistic impact on the subjective factors of quality of living and as it increases more, we have more subjective quality. These results tell planners that key factors would have great impacts and roles on the satisfaction of the life of citizens.

Dr Rostam Saberifar, Mr. Hosaein Jangi,
Volume 17, Issue 46 (9-2017)
Abstract
 
Experiences acquired in the reorganization of the old structures and buildings of the countrysides and suburbs show that Iran and other countries in the world, have not been successful, because of the inability to build and define a perfect house. This research discusses about the proper indicators related to appropriate houses from the perspective of those who live in such areas. Descriptive and analytic methods have been used. North East outskirt of ​Mashhad was the study ​area because a large population live in this region. The question is: Why people prefer to live in a house with a yard instead of an apartment. In this study,  410 persons were questioned. The collected data through the years 1391 to 1393 were analyzed by SPSS software. The Study shows that age, the year of buying the house, the educational level and the type of house possession affects the suburbs population's views. Therefore, if the governments consider these housing preferences and divide those people into certain subgroups, providing accommodation for them would be more successful.

Mehrshad Toulabi Nejad, Jaad Bazrafshan, Sirous Ghanbari,
Volume 17, Issue 46 (9-2017)
Abstract
 
In this study, the relationship between rural deprivation and environmental sustainability was analyzed. The present research is applied in a targeted, applied way and the method is descriptive-analytical. The data gathering tool was a questionnaire, an interview with the locals, a statistical journal of Lorestan province and data from the deputy of rural development and deprived areas. The statistical population includes rural households in Poldokhtar Township (N= 10619). Using Cochran formula and simple random sampling, 400 households were selected as samples. In order to identify the most important indices of deprivation from the exploratory coincidence rating test, One-sample t-test was used to determine the environmental sustainability factors and Finally, Tobit model was used to investigate the relationship between rural deprivation and environmental sustainability. The results show that the highest rate of rural deprivation is related to the economic and cultural deprivation. In the context of environmental sustainability factors, the results show that none of the factors is in stable condition. Water resources, trees, pasture, and pastures are in a state of instability and the only factor that has a somewhat stable status is the soil. Investigating the relationship between deprivation dimensions and environmental instability shows that the economic and social dimension of deprivation has the most impact and relationship with environmental instability. While cultural deprivation of the region, although high has had the least relationship with environmental instability. Therefore, it can be said that to reduce environmental instability and prevent environmental degradation, consideration should be given to the dimensions of deprivation and planning to reduce it.

Volume 17, Issue 46 (9-2017)
Abstract
Since the most important climatic parameter affecting sugar beet cultivation is the temperature, we carried out this research considering climatic elements such as temperature, precipitation and freezing days in relation to autumn sugar beet planting. Daily temperatures of selected stations in a period of 10 years (2005-2015) has been used for agroclimatic analysis. In order to evaluate that, thermal potential assessment, deviation from optimal conditions and active day gradient index (GDD) were used. The evaluation of thermal potential based on the threshold of 0, 4, and 10 degrees Centigrade at the station levels in Kermanshah province showed that Sar-e-Pol-e-Zahab Station has the highest cumulative thermal unit and Kangavar Station has the least one. In Isfahan province, Khour-va-Biabanak station has the highest cumulative thermal unit and Khansar station has the lowest unit. Based on the deviation from optimal conditions in Kermanshah province, Sar-e-Pol-e-Zahab station has the lowest (-27.79) and in Khour-va-Biabanak station (-21.78) had the least deviation from optimal conditions. Planting date at the stations was considered based on the autumn temperature. In Kermanshah province, Sar-e-Pol-e Zahab station had the earliest date of harvest (May 1st.), while this date in Isfahan province was for Khour-va-Biabanak station (May 9th.). Suitable areas for planting in Kermanshah province are found to be the eastern and northeastern regions of Sar-e-Pol-e Zahab and Qasr-Shirin. In the province of Isfahan, the northern and western parts of Khour-va-Biabanak and Kashan were the most proper regions and central areas are in the next steps.

Volume 17, Issue 46 (9-2017)
Abstract
Efforts to provide security have always been of great importance to human being. In recent decades, the security issues of climate change have attracted attentions due to its sustainable consequences on the lives and civilization of humans. Among all countries, the ones which are placed in draught belt, like our country Iran, have hurt a lot because of low precipitations and also mismanagements in water resources control. Climate change show itself by changes in precipitation patterns, reduction of precipitation and increasing of temperature. According to the present data, Iran's central drainage basin which consists of important geopolitical provinces, has been affected by the above mentioned factors. This descriptive-analytic research is carried out based on the effects of climate change on Iran's central basin which provides approximately 48 percent of Iran’s GDP.  Continuity of climate changes in this region can make critical problems in social, environmental, economic and political scales and the lives of the citizens would be affected as well. To conclude, the persistence of the current conditions in climate change in the central drainage basin of Iran, would result in challenges through the national stability and security.

Volume 17, Issue 46 (9-2017)
Abstract
 
In this study, to show the inequality between different cities in Ardebil province, 60 developmental indicators in different sections including health care, social, educational, cultural and infrastructural sections have been analyzed through VIKOR model. Moreover, for data analysis and graph and table representation of data Excel, SPSS, and ARC Map 10.1 software was used. For determining validity of the research indicators, questionnaires were completed by experts (16 experts and professionals in the related area) through AHP model. A survey in 2011 showed that from among 10 cities in Ardabil province, Ardebil city; Serein Germy and Khalkhal; Parsabad, Bilesavar and Namin; Meshginshahr, Nir and Kosar were developed, developing, less developed, and undeveloped areas, respectively. This inequality is the result of environmental, economic and political factors and it also reflects inadequacy of spatial planning, which places Ardabil in its high priority for development. Furthermore, according to the conducted analyses it is concluded that there is an imbalanced regional inequality on city scale in Ardabil province; there is a meaningful and positive relationship between the population of a city and the degree of its development; finally there is a meaningful and positive relationship between the distance from the provincial capital and the degree of its development.

Abstract
Therefore, this study was to evaluate the ecological potential of Ecotourism development in order to study extensive and focused outing in Shahreza County. In this respect, the ecological model of tourism development assessment was fitted. At first, data of slope, aspect, soil order, bedrock, vegetation, temperature and sunshine hour parameters were obtained, and the appropriate areas maps, from the perspective of each parameter is drawn with due observance of the principles and conditions of the said model, and apply the its thresholds. Then, the final mapping of focused and extensive outing of tourism development was drawn by the integration of prone areas maps. Eventually, the final layer of outing was assessing accuracy through the encounter of the natural attractions and rural centers layers. The results showed that extent about 9.0198 and 3.9526 km2 (0.32% and 0.14%) of the Shahreza County are appropriate for the development of one and two levels of focused outing, respectively. Also, extent about 263.1973 and 298.1843 km2 (9.41% and 10.67%) are appropriate for the development of one and two levels of extensive outing, respectively. The high adaptation of the natural attractions and rural centers to the classes evaluated of ecotourism development maps has been showed the acceptable accuracy of the tourism development and the spatial and land use management maps is the Shahreza County.
