The doctrine of South Korea spatial planning system in order to apply in the circumstance of Iran
2017
Akbari, Reza
Developing according to foreign investment in South Korea is an economic miracle of contemporary century. The evolution of economic miracle has been accomplished by complete success of spatial planning. The most striking feature of spatial planning in South Korea is its implementation. Using descriptive- analytical method, this paper will seek success procedure of South Korea spatial planning and basic role of government in order to respond three questions: how government of South Korea was able to achieve such successes? Applying spatial planning as a tool in this process, which role government play? And what doctrines have this experiment in order to apply in Iran? Spatial planning of South Korea implement in three scale of master land, regional and urban plan. Urban planning of Korea has a three-tier structure. Urban master plan determine long-term growth path and future image of city in the upper level, urban management plan present program of city with binding rules and objective details in the next level, and the manner of programs and necessary strategies implementation in the third level. Urban management plan, including zoning plan (land use), urban facility plan, Maintenance plan of the city (time-out texture) and detailed plan of regions, is an unique, thorough and so successful sample among different countries and its doctrine is exploitable for Iran which has no land use and urban facilities plan and no sufficient and necessary solidarity in the field of time-out textures and detailed plan. Administrative identical process, preparing all plans by executors and approving lower – rank plans by preparers of upper – rank plans are another striking feature applying in spatial planning system of Korea which is major factors of urban plans implementation.

In recent decades almost of land use changes without taking capabilities and limitations of environmental have caused environmental problems and known forms of soil degradation and aquatic ecosystem pollution. The purpose of this investigation is determining how to mitigate the effects of future land use changes in Tajan watershed by investigating ecological potential as a strategy for natural resource conservation. Therefore, the land change modeling (LCM) was used for the analysis of possible future land useand then using Geographic Information System (GIS) and multi-criteria analysis (linear weighted combination) was determined the most sustainability of agricultural areas. The results showed that during the period from 2010 to 2040, 34 739 hectares of forest land use were declined and 27 071 and 7668 hectares of agricultural lands and pastures will increase respectively and the 3473 hectares of the most susceptible areas possible change from forest to agriculture and pasture were extracted. So expect to assessing changes land use based on the ecological potential in the future can protect Hyrcanian forests for the prevention of unprincipled changes in the coming period in this region.

In order to land cover change modeling and detect to possibility of predict the future trend of Land Change modeler (LCM) was used. VNIR Data ASTER Sensor of TERRA satellite with spatial resolution of 15m for three periods 2000, 2007 and 2016 from Gilan-e-Gharb forests of Kermanshah province were analyzed. Land cover maps of years 2000, 2007 and 2016 four categories: forest cover, pasture lands, agricultural lands and built-up area areas for each of images were extracted. The results of data analysis in the first period (2000-2007) and the second period (2007-2016) showed the greatest increase in agricultural lands and pasture lands have the greatest decrease area. Based on these changes and by taking eight independent variable, transition potential modeling of 2016 was done using Artificial Neural Network. Then by hard predict model and images were classified of first period (2000- 2007), the land cover map in 2016 using Land Change Modeler was predicted. After evaluating the model, 83.09 and 71.10 overall accuracy was obtained for the first and second periods showed the consistency between prediction map and classified map of year 2016. The land cover maps by entering the second period (2007-2016) to Land Change Modeler the land.

Hosseini Dehaghani, Mehdi | Basirat, Maysam
Plan quality evaluation has turned to a significant approach considered by the urban studies both in order to help the success in implementation of the plan and to make better plans. Thus, the current study evaluated the "Master Plan of Pooladshahr City" as case study and used a framework for evaluation of quality of urban development plans based on the synthesis of Interpretive Structural Modeling (ISM) and Analytic Network Process (APN) methods. In fact, after extracting indicators of theoretical studies, the network connections between indexes is built using ISM and its output becomes as an input in the evaluation process of ANP. The most shortcomings of this plan can be considered as lack of public participation in plan preparation process, lack of use of scientific methods and local values in visioning, and adapting it with all the elements of the plan besides lack of indicators for monitoring the success. Although the efforts of the plan producers for inclusion of such concepts as sustainable development, urban competitiveness, public participation, etc. in a reasonable methodology which cannot be seen in the conventional service description of planning has been significant, it has not been much considered by the plan itself.

Hedaytifard, Maedeh | Kheyroddin, Reza
The diverse forces for location of coastal lands and the complexity of different and contradictory interests of these spaces asked new public management to cooperate with public sector and this was the beginnings of privatization of coastal lands. The review of experiences in different communities, shows the main discourses for creation of coastal exclusive spaces, including security, consumption and culture. This research aims to explore the categories of exclusive spaces in a case study and develop the current conceptual framework for the coastal exclusive spaces in pre-urban areas. With applying case study research strategy and the qualitative method approach, the documentary analysis method was used in which the coding technique analyzed the data, gathered from interviews, documents and local observation. It is found that security and culture does not make sense in the case study but for consumption, there is another category and that is the exclusive spaces created under the discourse of public good consumption with the support of governmental and state forces.

Taghilo, Ali Akbar | Aftab, Ahmad | Soltani, Naser
New models of development are based on tourism development and utilization from place – Space variations; therefore, identifying the capacity and capabilities of different geographical areas is in the center of development planning for fundraising and investment. In this context, the aim of this study is to investigate the feasibility of investment in the tourism sector with emphasis on Western Azerbaijan province. The research method was descriptive - analytical. Expert choice and GIS software for data analysis has been used. The results show that, about 12.45 percent of tourism areas have international and national range and about 18.68 percent have national and local range. Also, about 17.45 percent of the tourism sector has a range of appropriate local investment. Experts say that effective factors of tourism investment range are different (Thiel index equal to 55/0), and areas which are contiguous with city infrastructure and municipal services have a border range.

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.

Regional differences and inequality in many countries is a major challenge in the way of achieving balanced development goals, particularly those countries such as Iran which sovereign a large geographical territory. Due to past poor national and focused planning, development and its basis in geographical regions of the country, has revealed significant differences in the development process. Analysis has been done using documentary and survey data collection methods and a combination of quantitative and qualitative analysis. Data were gathered through documents, questionnaires and Delphi techniques. Then in the second stage of Delphi, using the opinions of experts and officials in charge of the study area, cross-impact matrix was completed in order to evaluate the impact of factors on each other in regional imbalances of Gilan province. Then, with the use of analytical techniques and software MicMac, factors related to inequality of Gilan province were studied and by analyzing the effect of variables in the creation of regional imbalances, the key factor ,”spatial one-dimensional development“ was identified and finally appropriate strategies to equilibra in Gilan province were presented.

2015
Kamyab, Hamidreza | Salman Mahiny, Abdolrassoul | Shahraini, Mohammad
There is competition between land uses in spatial land use allocation. In this research two approaches including Multi Objective Land Allocation (MOLA) and optimization with Genetic Algorithm (GA) were used for conflict resolution. The MOLA approach is based on suitability and proximity to ideal point whereas in GA, a suitability layer together with a cohesion index was used for land use allocation. The output from MOLA application was fed into the GA approach as the initial population and contiguity index as a landscape metric was used in the process to improve the result. With inclusion of contiguity in the GA approach which is absent in MOLA, and has no precedence in Iran, the final patches in the land use pattern were compacter and better shaped. Results showed GA application using MOLA output improves landscape metrics specifications in the final land use plan. However, including landscape metrics compromises suitability for land use, but there is possibility of balancing suitability and landscape indices in the GA application process. The final layer created through GA showed capability of considering suitability and landscape metrics simultaneously in land use planning towards achieving an optimal solution.
