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.

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.

Abstract This study aimed to assess the contexts and barriers to smart growth in Khorramabad city center has been developed as a town, Method employing descriptive - survey is based on a library of resources. Based on the results of the survey show those respondents' views; The most significant growth potential of applying intelligent city of Khorramabad can be admitted in terms of demand and incentives, he said. Physical and environmental conditions Khorramabad as the potential for growth of smart cities are considered.

It could have access to smart technology can play an important role in improving the living conditions of citizens may buy land.This will involve addressing important issues such as changes in system planning, urban management practices, infrastructure and culture is given.

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.

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.

Monitoring land use and land cover changes has an important role in planning and managing environment. Vegetative Zagros region, in terms of biodiversity and genetic reserves is very important. therefore, this research investigate the basic structure of Zagros vegetative landscape and then compare the northern and southern Zagros, in Kurdistan and kohgiloyeh and Boyer Ahmad provinces. For quantifying metrics related to the land use patches the analysis of the landscape metrics in combination with the gradient analysis method in GIS and FRAGSTATS was used. Results showed that the percentage of cover of sustainable land use for the province Kurdistan, is agriculture (45%), pasture (41%) and forest (12%) and for Kohgiluyeh and Boyer Ahmad, forest (45%), pasture (35%) and agriculture (12%), respectively. Generally, have Kurdistan province landscape includes the larger patches, and has simpler and more continuity, while Kohgiluyeh and Boyer Ahmad province goes toward fine grain structure.

Industrial revolution has had disadvantages despite its numerous advantages in all areas of human societies. One of the main problems our city planning is faced with these days which is caused by inappropriate special structure is the uncontrolled expansion and growth of cities. Urban sprawl growth is not limited to large cities but it has happened to small cities and middle cities as well. An example of such cities is Gonabad city and has had uncontrollably expansion throughout its life. The method of research in this study is an analytic-comparative and Shanon and Holdern entropy models are used together with ARC GIS software for preparing the maps and then the city growth pattern of Gonabad is analyzed at the end. The results that have been achieved from Shannon’s Entropy model, shows that physical development of Gonabad city have been reduce during the last ten years. Though this development has been irregular and uncompressed. Applying Holden’s model about Gonabad shows that during the years 1956-2006 around 51% of physical development has been a growth in population and 49% has been the horizontal and sprawl growth of the city that caused a reduction in population gross density and an increase in gross urban land per person.

Although Lorestan is a mountainous land in the middle bounds, of Zagros Mountains and has varied climate, watery rivers, new natural views, wetlands, waterfalls, lakes, forests, verdant pastures and its ancient civilization and history has excessive potential to attract tourists. And the it, hasn’t gained much success in affricating tourists until now present research seeks to identify development strategies in Lorestan.

Perception of urban development process in urban planning and management of sustainable urban development is important. In this paper physical and spatial development of Varzaneh city is studied and, after recognition of its potentials and restricts with using Boolean model and overlaying in GIS and also calculation of requisite space for the added future population optimum strategies for future development is suggested. The method of the research is descriptive-analytic and method of data gathering is documental-library. In order for completion of data and monitoring urban development of Varzaneh, we have accomplished field study and group interview with Varzaneh people. The results of the research indicated that initially urban development of Varzaneh has been was self-growing and have happened around the center of the city, but because of existing agric cultural lands. It was impossible to develop the core and the new city along with the old city has been developed (they separate from each other by the river). In new developing plans direction of development is to the north. The results also signified that not only it’s not necessary to expand the city for future development even when population are threefold rather than now but also altitudinal development of city is possible due to the free lands, urban sprawl and one- floor buildings.

Hydro geomorphology is a branch of natural geography that deals with studying the shapes of ups-and-downs which are resulted from the function of the water and streams, especially the rivers. Recognizing and expressing the hydro geo morphological elements and their functions on the primary structural surface in the Kheir Abad basin and also providing some practical plans to recognize and manage the environment of the region are very important. This region is considered as a sub-region of the Zohreh River in Kohkiloyeh & Boyer Ahmad province and this river is a sub-basin of the Persian Gulf basin. The Kheir Abad River is located in the province of Kohkiloyeh & Boyer Ahmad in Gachsaran County (located in the northeastern part of the region) which is the only main streaming river of this region that originates from the various subordinate streams (often as the seasonal rivers) of the northern, northeastern, eastern and southern altitudes, and finally it reaches to the Zohreh River in Kohkiloyeh County. The followings are the purposes of the present study: analyzing the role of the hydro geo morph logical elements of the region regarding to capabilities and limitations of the natural prospects and landscapes, providing some suggestions and strategies and applications for the region in the framework of the capabilities and limitations to reasonably use the available resources. The present and applied method in this study includes a filed one that can be a suitable method to achieve investigative purposes and evaluate the hypotheses. Examining the physiographic, hydrological and hydro geo morphological elements, the geology, climatology, soil and flora and filed studies in the region with the help of determining and analyzing the influential elements in land-forming process, Geo morphological shapes which are present in the region and their developmental conditions reveal significant role of streams.
