The appropriate locate of uses and the justice of in Spatial distribution is very significant in planning the urban land use. The high increase in physical and population development of city، the shortage of services uses and lack of equity to allocate the sorts of land uses in various areas in Kashan، cause the confusion in urban land use and endanger the city sustainable development. However، recognizing and revising each one of the city uses to achieve the appropriate criteria and the principles of planning in city sustainable development are the most important activities in this field. The method to the research is descriptive -analytic، which has engaged in assessing and evaluating the quality and quantity of urban uses in Kashan، by considering two significant and effective standards in land use (including capacity and social justice) and putting GIS software into operation in the framework of entropy standard model and the average of nearest neighbor and per capita standard. The results of the research indicate that uses do not have appropriate Spatial and locative distribution، so that analyzing them with the capacity indexes and social justice، indicates the quality and quantity commotion in uses of tenfold areas in Kashan.

Balancing in territories settlements، especially in the urban systems، is important for spatial planning. According to studies carried out in a non-equilibrium state of the urban system and the primacy phenomenon is evident at national and regional levels in Iran. The purpose of this paper is to explore the urban hierarchy of Qom province، especially in the course of time. This study، is descriptive and analytical method and developmental research by purpose. Documentary methods have been used for data collection. In order to analyze the urban system has been used many indicators (primacy، two city، Mehta، Moomaw&Alwosabi، Kinsburg، scattering coefficient، Herfindahl، Shannon entropy، size- rank and improved size-rank). The results show province of Qom has 6 city that all cities don’t have record high urbanization except the city of Qom. Also، all indicators show that the city of Qom has the strongest urban prime rate، concentration and imbalance. Even become the province of Qom and the formation of new urban areas couldn''t reduce imbalances.

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.

These days because of study process changes of land use into urban use، play an important role in long-term decision and planning، predicting process of land use changes and it''s modeling with specific methods to manage and control of urban expansion is necessary. In the meantime one of the modeling methods of land use changes is Clue-s model. This model is used recently in urban studies، because of it''s dynamic nature، ability to combine with other tools، ability to improve the model and accessibility of essential data. At the first step the articles purpose would be the explanation in ways and amounts of unused and agricultural lands conversion into built areas within the Esfahan 14''th region، and the next step would be future patterns modeling of these changes till 1405s vision with Clue-s. The theoretical principle of this article have been collected with documentary method and quantitative and comparative method have been used to analyses the topic. At first، effective factors of land use changes have been prepared and then to explain the relationship between changeable factors and independent factors، causal analysis Regration Logistic have been used within SPSS.

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.

Boarder villages of sistan region in Iran are so less developed and their location on the boarder of Afghanistan has fueled this less development. Subsequently، Afghan''s settlement in this region has caused some special socio-economic situation in sistan region and has overwhelmed lots of functions of this region''s villages. The goal of this article is an analytical study on the effects of Afghan''s settlement on the socio-economic development of boarder villages of Sistan. Based on the library study، field studies and questionnaire the method of this article was description- analytical study. The collected information was analyzed by means of Taxonomy method and spearman test inlet in SPSS software. The results of level taxonomy showed that among the 31 studied villages the number of 6 villages were on normal level and 25 others were on middle level or bellow. Also the results of spearman test with a degree of 99 percent certainty shows the correlation between afghan''s settlement with economic development (-0. 814) and social development (-0. 679) and concluded that the socio-economic situation of the region will improved by afghan withdrawal from Sistan area.

Spatial planning concept refers to alignment and arrangement of relationship between people، space and activities at different geographical scales with emphasis on the role of decision-making and decision-taking. Objective of this research is investigating the spatial distribution and localization of therapeutic land use (important hospitals) of Mashhad city with passive defense approach. Although، emphasis is on passive defense approach، however، because it is closely tied to the issue of spatial planning (especially in urban scale)، the findings of the study can also be effective in spatial planning and urban planning. Study area is city of Mashhad that with regard to the diversity of therapeutic spaces، major city hospitals were selected for final consideration. Research methodology is descriptive - analysis method. Findings of Research indicate that the main part of important hospitals in Mashhad have been concentrated in the central part of the city. These regions located in areas of high risk in terms of passive defense. Imbalance between density population and spatial distribution of hospitals in urban areas is strongly noticeable. Finally، with attention to investigations and results، some suggestions for reduction hazards of therapeutic spaces in times of crisis offered.
