Hataminejad, Hossein | Rajaei, Seyed Abbas | Salarvandian, Fatemeh | Teimouri, Iraj
One of the basic and important fundament of sustainable development is Land use planning and use of appropriated with environmental characteristic and use correct of natural sources in the region and country. Ardabil province is one of the regions that its land use in some of its places is not appropriated with ecological potential, especially in the Lands which they are under cultivation. Therefore, this article have intend to analogy of land use now with ecological potential in the province. To prepare the map of land use, utilized the ETM and ASTER image sensor 2002 and so used from information layers in the linked organizations and ground survey. Analogy of ecological potential in the province is done in the GIS and according to method of Makhduom of course with slightly changes. We compared the ecological potential with land use of the province by overlying of different layers. The maps of region’s ecological potential were prepared with overlying of different layers by combine code in GIS. The Results show there is disagreement in the Dry farming areas with ecological potential. In other words, that is 37% fields of dry farming and 6.7% cultivate in the country of Ardabil not agreement with ecological potential.

Hajinejad, Ali | Rahimi, Dana | Taghizadeh, Zahra
Nowadays, tourism development in rural capable tourism sample areas is one of the ways to save the villages from poverty, immigration, social and economical problems. So, the present study identified the environmental potential of the tourism sample area of Hajij Village through using a set of internal factors (strengths and weaknesses) and the external factors (opportunities and threats) and then, codified the tourism strategic plan in this area. Accordingly, the present study was an applied-developmental research with descriptive-analytic methodology. The data from questionnaires and field studies were survived in order to determine the four dimensions of SWOT technique. The research had a simple random sampling including tourism experts and scholars in the province. The findings of the study showed that Hajij Village had 11 strengths, 11 weaknesses, 12 opportunities, and 6 threats, which according to priority of these factors, T2, W3, O2, and S4 had the most scores.

Many human activities due to the lack of consideration in environmental restrictions on the landscape ecology are influential and have severe environmental effects on natural ecosystems. This study was conducted to investigate the trend of changes in landscape ecology in Dehloran, Ilam. For developing maps of Land cover, and analyzing the changes, we used, respectively, the satellite images of (1985) TM and (2007) ETM + were applied and landscape metrics of class area, density of patches, number of patches, mean of patches size, edge density and mean of shape index Various class-level landscape pattern metrics were calculated using FRAGTATS, in order to analyze landscape fragmentation. The analysis of landscape metrics revealed that the extensive replacement of fair rangelands by agricultural lands, rangelands, residential areas and barren lands. The results showed that increase in the number of patches and decrease in the mean of the area size was an important indicator of significant index of degradation, and the process of degradation and destruction of landscape ecology was in an increase mood. Therefore the results necessitated paying attention to the quality of land use and cover in the region for to exploit natural resources appropriately and sustainably.

This study conducted to locate the landfill in the range of studies, in view of the most recent guidelines Environment Protection Organization of Iran as to the citation Article 12 of the law and article 23 executive bylaws Waste management In order to Reducing the damaging effects of environmental Activities, locations and Utilities Related with the Processing and disposal Ordinary wastes, Including all the places of burial and recycling Has been prepared. Using the screening regional method and GIS, the Legal-restricted areas as well as the fit regions for waste disposal at the regional scale reviewed and was specified. Then, fit regions in the local scale with regard the important parameters in this method and the weight of them have been Priorities. Three main natural conditions، land-use and economic factors was interference in this method. Then, based on the population growth rate and the amount of waste produced in a horizon of 20 years the area of land required for landfill in the Study area specified and Lands prone with an area of less than the amount determined is removed from the map of merit and was provision the final suitability maps include appropriate land-landfill by taking all the conditions and criteria of the environment protection organization of Iran was determined prone for landfill the 2770.7 hectares at regional scales and 2105.6 hectares of land at the local scale of the whole range of Studies.

Daheshvar, Tahoora | Danehkar, Afshin | Ale Sheikh, Ali Asghar | Ahmadian, Reza
Aim of this study is to identify suitable Urban Development spots with application of Environmental Criteria in Mahmoodabad Township. A series of criteria were identified by investigating various sources about the location of urban development to achieve the aim of this study. Then criteria were selected by Delphi questionnaire or survey experts. So 12 criteria and 30 subcriteria were selected for urban development site selection in Mahmoodabad Township. These remained criteria which can convert to maps were weighted with AHP method. Then criteria were converted to maps by Arc GIS software. After that the maps combined with a weighted linear combination by Arc GIS software and appropriate spots for urban development were chosen. Area of the biggest spot is 0/7 square kilometers and area of the next spot is 0/4 square kilometers. According to 26th article of executive regulations for new towns building, minimum area of a new city is 3 square kilometers. So, none of the spots are suitable for urban development. Results and the criteria which obtained in this research can be used as a guide in areas that have similar features (north coastal area of country) to Mahmoodabad Township.

Mosayebi, Samaneh | Taghdisi, Ahmad
Increasing young population and rising unemployment has led to employment and related indicators of serious problems and controversial country. In conjunction with the study and research on employment provinces, a variety of variables and factors involved and It seems that the lack of balance in the distribution of these variables, social inequality, economic, political and cultural between the provinces follow. Indices of employment in the provinces spatial distribution of employment index shows. The main purpose of this study is to clarification social inequalities of employment for equal distribution of possibilities in provinces. In this paper 55 softened are used. Variables dropped to 10 by means of advanced statistics methods such as factor analysis and presented in combination with meaningful factors. The importance of every factor is given too. Then the country provinces were divided into five equal classes by the cluster analysis model. The research results indicate this fact that there are serious imbalances in the country. So that in terms of employment Tehran province is in the first and south Khorasan province in the last place.

Jozi, Seyed Ali | Rezaian, Sahar | Irankhahi, Mehdi | Dabiri, Farahnaz
The purpose of this study is to determine the potential of development in partial of Bandar-Abbas city, using degradation model and analytical capability of GIS. In this regard, firstly the study area was divided into 149 grid cells of 900 hectares (6×6 cm; on map of 1:50000 scale). Then, on the basis of degradation model, destruction coefficients have been calculated in all units of network. Ecological vulnerability has been calculated and classified by using biophysical maps. Then, in the next stage, destruction factors has been determined and calculated also physiological density has been calculated and in final, destruction coefficients have been calculated in all impact units. The results show that 130 units (87.23%) of network; need to be restoration and 18 units (12.07%) require protective actions. In the study area, areas with prone to develop has achieved very small percentage (0.67%). This paper suggested applying environmental educations for beneficiaries and attractive their collaborations, to set environmental management system in industrial factories, and to apply environmental capability evaluation and supervising on implement of state land use plans and EIA to prevent of the destruction.
