Positioning services are generally the activities in which all the features of a particular area are analyzed with regard to suitable land and its relation to the urban and rural functions. Choosing a location requires knowledge and accurate assessments, using appropriate models and tools. In this survey the was conducted in compliance with the standards and features of the site issue Geomorphic region has been examined and is The most important aim identify the status of military centers in the region and analyze environmental conditions and introduce suitable location for the construction military centers. The study is a descriptive-analytical one and benefiting from GIS, evaluates the border areas of South Ilam province and the positioning for the establishment of military centers with regard to the geomorphic and human criteria. therefore AHP model of GIS was used to determine the distribution of military centers of this area.

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. The results of present research led to offering lands zoning map of the under studding area based on Ecological capability assessment of urban development to optimize activities in order to preventing environmental imbalance.

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. Since there are a few situations in which settlements have all of the criteria, it can be concluded that the locations of these villages are appropriate from studied criteria, so the hypothesis is supported.

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.
