Afrakhteh, Hassan | Riahi, Vahid | Jalalian, Hamid | Saraei, Soodabeh
Spatial justice with scientific and humanitarian teachings, cause the weaknesses and strengths in different areas. Since most of the allocation and distribution of national and regional resources in the country through focused planning, The present study is an analysis of spatial justice of rural services in the Isfahan province. The research method is descriptive and analytic. The required data were collected through documents. This study, using the 8 Rural Services measures consists of 77 variables was performed. Data were analyzed using SPSS and Excel. Validity of measures confirms using factor analysis and then used as input to numerical taxonomy technic. The obtained results using the GIS software were designed as a map and charts. In this research counties were divided into three groups in terms of distribution of rural services. The results indicated that there is inequality in the distribution of services and showed that rural services are not distributed fairly in the counties of Isfahan province. In other words, in the sparsely populated areas, focused service centers and in more densely populated areas, the lack of service evident. And for rural service delivery in the Isfahan province not pay any attention to important factors such as population.

amanpour, saeid | mohamadi deh cheshme, mostafa | alizadeh, mehdi
The occurrence of natural and human disasters can create heavy casualties in cities and urban areas and such a critical issue makes it inevitable to pay a great deal of attention to the vulnerability and safety aspects of cities and the accessibility to the urban welfare standards from the perspective of passive defense. The geostrategic location of Koohdasht city in Iran and its vulnerability against medium risk earthquakes as well as the strategic defensive role of the city in western parts of the country highlights the vital importance of vulnerability against earthquakes in Koohdasht city. This is a descriptive analytical research with a theoretical- applied essence. In order to achieve to the objectives of the survey, the critical and sensitive uses were identified based on the existing references and the spatial data bank was extracted using Delphi method and based on a survey consisted of 20 pundits. On the other hand, the principle of adjacency was taken into account. Based on the effectiveness of various indicators the combined model of FAHP-GIS was utilized to design the location model and the final raster of the vulnerability of urban infrastructures was provided using Arc GIS software and Spatial Analysis tools through the application of fuzzy overlay functions. The results of the study indicated that about 68 percent of the city infrastructures by meeting the conditions of adjacency between 0.29-0.55 and the vulnerability in the range of 0.45-0.71 fell in the high vulnerability zone.

Hasti, Farzam | SalmanMahiny, Abdolrassoul | Joolaie, Ramtin
The present study aims to provide a solution to optimize land use through multi-objective linear programming, and to solve the conflicts generated in the process using game theory, in two cities of Gorgan and Kurdkoy, Iran. The primary land use planning was completed for seven land use through multi-criteria evaluation and then a first allocation was implanted using MOLA. In the secondary land use planning phase, land use optimization, with multi-objective linear programming was conducted considering economic-social and environmental needs. Environmental requirments such as reducing runoff, non-point nitrogen pollution and soil erosion, were modeled using L-THIA and RUSLE models. For socio-economic parameters job, profit and initial costs were considered. To finalize, a multi-objective linear programming model, was designed. The environmental and socio-economic stakeholders have different needs. That creates conflict in the land use planning process. In the final third phase of the land use planning, game theory was used to resolve conflicts. Environmental and socio-economic players were allowed to play scenarios in triplicate. The results showed the winning changes in land use to the extent that an equilibrium between interest groups was reached.

2016
Irankhahi, Mehdi | Jozi, Ali
The present study has been conducted on Shemiranat county landscape, using lattice hexagon approach, for the first time, in order to achieve homogeneous units in degradation model. To this aim, with respect to the extent of the studied area, a lattice hexagon composed of 36 units (cells) was created and each grid cell was considered as a sub landscape. Next, ecological vulnerability, degradation agents and their severity was calculated for each cell, using landscape metrics and then classified and standardized based on fuzzy logic. Eventually, according to the obtained degradation coefficients, landscape zoning and analysis was done. Overall, 73 percent of the Shemiranat County was identified as with low degradation area which is developable with paying attention to ecological restrictions and buffers (distance of river valleys, main faults and protected areas). Also, 23 percent and 4 percent of the studied area was determined as need rehabilitation and needs protection, respectively. Using the lattice hexagon as the basis of landscape degradation assessment, in addition to more accurate calculation of metrics and estimation of the degradation coefficient, separately for each homogeneous cells, landscape degradation status and future development potential will be determined.

2016
Arbab, Parsa | Basirat, Maysam
This article, with a focus on the change and transformation process of the approaches and trends affecting the new towns policy, scrutinizes the first and second generations of the new towns in reference to the South Korea as a case study. The first generation of new towns development in South Korea is associated with the rapid growth of urbanization, industrialization and subsequently economic increase of this country. Lack of housing and inadequate housing supply, formation and growth of the informal settlements especially in connection with Seoul, and the subsequent centralization in the Seoul metropolitan area are the main and significant urban challenges of South Korea in this period. The second generation of new towns has been planned first with the aim of housing supply as their main function in the capital region. These cities are the result of approach that follow the qualitative, gradual and planned development in the form of small scale but multiple projects compared to the past. Decentralization of Seoul and Seoul metropolitan area, integrated regional development, and ultimately the balance of South Korea’s national territory are the key purposes of this process, in terms of spatial planning.

2016
Sharifzadegan, Mohammad Hossein | Fathi Farzaneh, Amir
The consideration of Tehran metropolis and its soundings areas has been the first one of recent challenges in Iran’s spatial planning which made it possible to develop the concepts such metropolitan region and conurbation. However, it is obvious that there appears to be a much more proper structure due to neo-regionalism and globalization in order to understanding of dynamic nature of Tehran and its surrounding. Nowadays, spatial phenomena have probably influenced by the physical and political boundaries which did not make the functional nature of interactions of these regions. City- region is among concepts that have not received due attention in recent years and was only discussed and presented in academic circles. This is perhaps a result of too much focus on the issues within cities. This paper has tried to present an optimum city-region spatial model that matches the spatial structure of our country as much as possible. After determining the required indexes by using of 85 city points in 250 kilometers distances from Tehran, the spatial boundaries of Tehran city-region is determined through flow analysis and estimations of distance from center and finally, by the using of analytical and adaptive methods the spatial model for Tehran city- region, with two cores and 41 peripheral cities will be presented. It is the functional foot print of Tehran metropolis based on daily and weekly commuting by a spatial logic.

Saeed Sabaee, Maryam | Salman Mahiny, Rassoul | Shahraeini, Seyed Mohammad | Mirkarimi, Seyed Hamed | Dabiri, Nouroddin
Creating and preserving large patches in land use configuration and satisfying compactness and contiguity in land use configuration are nature-prescribed and nature-inspired criteria that can be used in land use planning better that before. Accompanying compactness and contiguity as the important landscape metrics in land use planning and land use configuration is close to applying proactive approaches rather than assessing the intense of Human activities' impacts on environment after its altering. To explain how to introduce compactness and contiguity to a land use configuration study, we assume the study area as a matrix that every cell or pixel of the matrix has the color or value that shows the type of land use. In this situation, the compact configuration will be made if the same color or value pixels are located adjacent to each other. With respect to this premise we defined some equations to achieve compactness and contiguity in land use configuration. Finally, we tested the equations in applied case of land use planning in a part of Gorgan Township. We applied hybrid of linear programming and ant colony algorithms for testing suggested method. The results show that the method can be succeeded in achieving these criteria.
