Redefining the Role of Small- and Middle-Sized Cities in the Regional Development Process; Introducing a Spatial Based Applied Method (Case Study: Kurdistan Province) Texto completo
2018
Ghorbani, Ramin | Pourahmad, Ahmad | Hatami Nezhad, Hossein
Much quantitative research (and some qualitative cases) has been done on the role of small- and medium-sized cities in regional development. The present article is also in this line, but with a slight change in the structure of the breakdown in the approach to the subject and the analysis of the problem, and the multi-faceted analysis of the data using the Fuzzy Inference System. The purpose of this research, with regard to the title, is developmental-applicable and has a descriptive-analytical approach. The FIS application and increasing approach has four stages (in general): its Database and Fuzzification; the rules base; the engine; and the Defuzzification. In the glimpse (Knowledge Base), regional development indicators (10 indicators) and variables (more than 70 variables) in four pillars of regional development (economic, physical, infrastructure and human development) for the small- and middle-sized cities of Kurdistan province (9 cities of the city centers Except for Saravabad) were selected and mapped in 2006 and 2016, and then a detailed analysis of the process was performed on the data. The final result of this paper is that although fluctuations in the development of the inland region of the province have been observed, regional development changes (relying on economic indicators) have been consistent with changes in the urban hierarchy (demographic projections). Thus, with the decline of concentration and concentration in Sanandaj, we see an increase in the role of small- and middle-sized towns in the urban-regional development of the province.

Alizadeh, Shahmorad | Mohammadi, Hossein | Kardavani, Parviz
Drought changes for optimal operation management of water resources well is the sensible. That's why last round of very extensive research on modeling drought in the world and Iran is and using their water projects and has conducted numerous hydraulic. One of the goals dynamic systems modeling potential policies to improve system performance. Modeling SPI index as an indicator of the country's drought situation stations using radial neural network model for each station was done. Independent variables neural network, relative humidity, temperature and lack of objects, which were selected according to their impact on precipitation. SPI index is the dependent variable. In total period of 42 years calculated by SPI, 12-month and 348 standard score by calculating the SPI 24-month, 336 standard score is obtained for each station. At all stations, ETo values from January to July to December increased and then fell in July to its maximum level reached in all stations. The highest average monthly ETo values in Abadan and Ahvaz stations in July and 18/232 and 16/214 mm respectively happened.

2017
Mousavi, Mir Najaf | Kiani, Mostafa
The government system of' Iran is centralized, and because in unitary and single power states, the security of political center (capital) with the total security of political system (National Security) has a direct relationship, the capital movement in Iran becomes important from two aspects; the first is to organize Tehran city and balance urban and regional system of the country and the second is to maintain the political security of the country. Capital movement from Tehran to other cities has been among the issues for more than 220 years but nothing has been done for some reasons. The aim of this paper which is written by descriptive – analyzing and survey method is to identify the main obstacles and the challenges of processing the capital and to present the strategies to remove the obstacles. So 7 elements as Economic, political, security, executive, social-cultural, legal and natural-ecological elements are selected in 55 items and are weighed by the academic elite people. After analyzing the information and using the structural equations model the results showed that the legal factor holding 10 items has the most direct (0/089) and indirect effect and the natural-ecological factor has the least effect (0/033) in moving the capital. Also the results of the network analyzing model for preference survey showed that the experts give priority to executive obstacles which hold final weigh 0/218 and compatibility rate 0/022 stands at the first grade in the priority survey of the obstacles.

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.

Seyedin, Afshar | Amini varaki, Saeed | Rostami, Hussein | Yazdani, Mohamad Hussein
Although Iran has a strategic position in the Middle East and there are threats of neighboring and non-neighboring countries, projects and economic infrastructures have been established without proper defensive considerations and are targets for enemy threats and other offensive actions. The present study is an applied and developmental research that aims to study and scrutinize the vulnerability of infrastructures in Ardabil province from the perspective of passive defense. Moreover, analytic network process (ANP) approach is used in GIS environment with elements of physical and biological environment, accessibility, and infrastructures in order to carry out the research. The results of spatial pattern analysis and vulnerability zoning show that the spatial distribution of infrastructure in Ardabil province is cluster type (non-dispersive) and in terms of vulnerability, 7% of Ardabil province is located in highly vulnerable areas which are themselves among the most densely populated places with high amounts of established infrastructures. This is due to poor physical indicators and lack of sufficient managerial, industrial, and military institutions in these areas of the Ardabil province.

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.
Mostrar más [+] Menos [-]The Lattice Hexagon Approach Applied in Landscape Degradation Assessment (Case study: Shemiranat County) Texto completo
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.
