In Iran, Urban land use planning is done in format of the comprehensive and detailed plan but, even after near fifty years of development of land use plan, there are still critiques together with some revisions in legal proceedings, content and procedures. This article is a study of evaluation of urban land use planning in current decade and specifically assesses urban land use planning in Bojnord’s detailed plan with indices of Place check and Needs assessment. Results of Placecheck indicate that only 7.92 percent of proposed land uses are fulfilled, while 34.8 percent have been abandoned and 57.28 percent underwent change of land use. Therefore, it can be concluded that Placecheck of uses has played a very small role. Result of Needs assessment index also signifies that 47.61 percent of the surface areas have realized proposed use. This shows that Needs assessment has equally failed but, compared to the other index, a flexible locality of uses contributes to realization of proposed plans. In the following and in form of interviews with executers, various obstacles on the way of realization, problems like land ownership, insufficient correspondence between planners and executers, and inadequate legal surveillance and obligations were indentified.

Modeling urban development patterns is an important technique for understanding complex urban growth processes. In this study, Logistic Regression model was conducted to model urban growth pattern of Gorgan area in North Iran, during the period 1988-2025. To do this, remotely sensed imagery of years 1988, 1998 and 2007 were used to produce land use maps. Also, dependent and independents variables were created to perform urban growth pattern modeling. Then, urban changes were detected during 1988 – 2007 and urban change modelling was achieved using Logistic Regression. After that, future urban grow pattern was predicted. The results indicated that urban areas have increased during study time period. Validation of model results was performed using Pseudo-R2 and ROC values which were more than 0.27and 0.83 respectively. Furthermore, Logistic Regression was applied to predict urban growth patterns for the years of 2016 and 2025. According to the results, appropriate implementations are needed to control land use changes, particularly urban growth, in order to preserve environmental as well as ecological balances of the area. The result could be help the managers to monitor and prevent the unplanned urban development in future. Model’s extracted maps can be used for managing and controlling future urban development.

Zali, Nader | Mansouri Birjandi, Sara
The planning literature has passed the prediction, forecasting and exploration of future concepts and has reached to futurology and foresight. Regional development planning is not exempt from this and needs a futuristic approach in order to be used after being planned. Identifying the future uncertainties and the underlying assumptions in the regional development planning by which the long-term plans have been established, is one of the most important main fields in the identification of problems and facing challenges of development documents. Post-planning also deals with the success or failure evaluation of the developed policy and planning in the future time horizon. Assumption Based Planning (ABP) is one of the post-planning methods, which could be used in preparing stable and compatible programs. This research is a combination of documentary and surveying methods in terms of the research type and is analytical and exploratory based on the new methods of futurology science in terms of the research nature which is conducted by a combination of qualitative and quantitative models. Data collection methods and techniques Delphi questionnaire was used and questionnaires are experts in developing and development issues surrounding region During two separate questionnaires have been completed. In this way, the correlation between each strategy uncertainty with mining experts from both questioners (strategies, inventory uncertainty) is calculated. The results show which areas are considered the most vulnerable strategies. Analysis of the results indicate that utilizing the ABP could be implemented in the regional development planning, which helps planners to have a consensus and commitment to the output. Thus, weaknesses and waivers existing in the long-term regional development planning could be identified and reviewed by utilizing the ABP.

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.
