Nowadays as for increasing growth of urban population and then expedite and ungovernable development of cities, many issues and problems have been stand on human societies The assessment of change rate of urban settlements in Sari city in the past half-century shows significant increment of urban lands space over the city. Increment of urban settlements in mentioned area takes place regardless capabilities and restrictions on lands and also ecological capability assessment process of urban development which causes wide range of valuable lands to be destroyed. Ecological capability assessment process of urban development estimates possible utilization of human from land for urban development usage. The present study which is descriptive and analysis and applicable research, is done to achieve designing and using a holistic and flexible model in order to ecological capability assessment of urban development by utilizing ANP. Analysis network process is relatively a modern method in the field of environmental researches that is based on mutual influence of environmental standards and of course wisdom collective judgment.

After movement decision, determination of new location is one of the most critical steps in the process of movement. The reason is that the results of movement, which have several different aspects, are emerged in the long term. The previous experiences showed that the nonchalance in locating the new settlements leads to failure of several movement plans. This study is a descriptive-analytical research. The purpose of this study is to evaluate the movement plans of Larini olya&sofla and Farrokh Abad in Ilam Province in terms of location through method of McHarg, and its needed data have been gathered through fieldwork and text study methods. The findings revealed that from perspective of a large part of criteria, the villages are in the appropriate and semi-appropriate conditions, but the slope of Larini village is inappropriate and Farrokh Abad village is inappropriate in terms of exposure to agricultural lands.

Safiisabet, Naser | Esmaailzadeh, Hassan
During last two decades, rural-urban linkages in the form of regional interaction networks have been analyzed particularly in the geographical literature. In respect to economic linkages, periodic markets network could be assumed as one of the most important markets. In the sustainable social- economic conditions, this can result in positive and reciprocal functions. This study aims to determine the role of periodic markets network in regional development around Tehran metropolis. In this descriptive-analytical research, 199 sellers and 384 buyers in 49 periodic markets surrounding Tehran Metropolis were studied. To measure the effective factors in the establishment of periodic markets network and regional development, five indicators such as population size, share of urban wholesalers, share of urban and rural street vendors, share of agricultural and non-agricultural products and share of intra-area and regional transportation network were chosen. Results showed that population size and the convergent role of rural and urban street vendors associated with the development of intra-area transportation network were effective in the establishment and sustainability of rural and urban periodic markets network and regional development. It is proposed to note promoting share of direct supply of rural agricultural and non-agricultural products to these markets for rural- urban balanced development.

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.

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.
