Urban land use and its location has always been an interesting topic for urban planners. As experts have tried to focus on the context and surroundings proximity, neighborhood, compatibility and incompatibilities, utility and other factors. By the expansion of geographical information systems, it is possible to focus on these factors and their impact on the planning process for land use allocation. At the same time, many scientific efforts have been made to integrate these systems and multi-criteria decision-making methods in order to enhance their ability to support decision making. Methods used in this field have also been widely used in various studies; one of the most important applications of these methods in urban planning is to determine the suitability of each parcel for allocating urban land uses. In this article which is applied in terms of purpose and is descriptive analytical in terms of method, the land-use suitability analysis as a scientific technique along with linear combination, and Delphi methods, have been used. Findings, which have been obtained from overlaying analytical maps (land prices, access to communication axes, number of blocks of land and air pollution's maps), indicate that what type of land use is more suitable for each parcel. The results of this paper are presented in the form of land use allocation scenarios. Comparison of the results of modeling with current situation shows that out of 2,166 parcels in the study area, 521 have no suitable uses and need change.

Land suitability evaluation plays an important role in environmental sustainable management. Besides, it is a prerequisite for land planning which affects sustainability of the activities and sustainable development. The current study aims to evaluate and model the agricultural, urban and industrial development in Great Isfahan (as the most crowded center of Isfahan province and the most important agricultural and industrial hub of the country) using the data in 2018. Land-use planning is increasingly focusing on the aspects of environmental conservational and sustainable development. Choosing the appropriate areas for this purpose is a complex process which requires lots of effective factors. We use multi-criteria evaluation of the land-use allocation models applying geographic information system. First, the required data (including topographic variables, water resources, geology, land-use, accesses, infrastructure factors, biological resources, soil and climatic parameters) were identified, suitability maps were prepared using fuzzy method, and the weight of the factors was determined employing the analytic hierarchy process. Then, the prepared maps were combined using the weighted linear combination method. Finally, the final maps of land-uses suitability were prepared and classified according to the expert opinions. The findings show that approximately 586.9, 197.2 and 24 km2 (20.3%, 6.9% and 0.08%) of the total area of the region is suitable for agricultural, urban and industrial development, respectively. Besides, the northwest and southeast of the region are in an appropriate area. We conclude that MCE and GIS techniques are effective tools for land evaluation and planning. The results of the present research can be used as a multi-criteria decision analysis to obtain a deep insight into the sustainable use of natural resources. Moreover, three possible scenarios (current ecological and socio-economic trend, conservation of agricultural lands and urban-industrial development) can be designed and modeled based on.

Optimization of land use allocation as one of the best models for environmental protection and coordinating different economic, social and other land use goals. The 10th Region of Tabriz has been inadequate in terms of fitting and optimal distribution of applications. Therefore, this study aimed to optimize land use allocation in 10th Region of Tabriz metropolitan. The present research deals with the nature of developmental-applied and descriptive-analytical method in the allocating land use field using eight main uses: housing divided into three classes, commercial, educational, therapeutic, cultural, green spaces, sports Commercial-residential, categorized by three types of classes, is based on the multi-objective genetic optimization algorithm, the second-class non-occupational sorting (NSGA-II). To this end, four maximum nonlinear objective functions are used: maximizing FAR, maximizing economic profit, maximizing adaptability, compression maximization. Eight types of land use and eight limitations were defined, and the combined weight method was used to combine the numerical value of the objective function after normalization. The NSGA-II operators were modified and the proposed model was developed in the MATLAB programming language. The model was implemented according to the modeling constraints. To illustrate the output of the model, the special coding method for solutions that defined the output was defined by the GIS software. The results indicate the effectiveness and effectiveness of the proposed model and its potential in supporting the urban planning and decision-making process. This potential is achieved through the production of alternative alternatives and the display of optimal solutions. The results of this study showed that in the case of optimization of land use in the 10th district of Tabriz, the FAR value is 13.04% and economic profit is 21.06% and compatibility-compression between applications is 2.3 and 4.6%, respectively.--

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 activitie's 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.

In this study, a group decision-making approach based on Geographical Information System (GIS) has been developed for solving educational land use allocation problem. Most researches conducted in the field of land use allocation, use multi-criteria decision making techniques with a view individual decision. However, in this article, land use allocation problem has been considered as a group issue that requires the participation of different expertise and perspectives in the decision making process. In this context, Analytical Hierarchical Process (AHP) method is used to determine the weight of criteria and aggregation of individual judgments (AIJ) method utilized to aggregate priorities of decision makers/experts.Proposed model has been implemented at district 6 of Isfahan as a case study; to allocate educational land uses and the results has been compared to the outcome of individual decisions. To allocate high school as an academic land use, land per capita, minimum area, distance to city centers, distance to dependent land uses such as libraries and distance to urban roads, have been considered and modeled as criteria. Utilizing a sensitivity analysis and comparing the result of individual decisions (each expert) and group decision (AIJ result) is showed some disagreement. However, all experts are dedicated same priority for the first three sites with plot number 5453, 4 and 9 to allocate as high school. The results indicates that group decision making approach in land use allocation problem make it possible analysis of opposite ideas offered by different experts and help decision maker to choice an alternative (site) obtained majority. In this research we consider same weight for all decision makers. In fact, each expert based on his knowledge and skills should have different weight that must be considered to aggregate individual judgments. Also by using fuzzy based methods, we can involve uncertainty of judgments and decision making at the proposed model. This would be considered at the next work of the authors.
