Green spaces and urban parks should be considered among the most fundamental factors fo the sustainability of natural and human life in today's urbanization. The Selection of optimal sites for the construction of green spaces and prioritization of these sites based on different criteria can be considered according to the spatial condation of the studied area. In this study, It is tried to provide sutible plase for the construction of green space in Ardabil whih criteria such as: Economic, situational and proximity in the form of ANP model using the overlapping functions of the geography information system. The analysis of data is used from ARC GIS, MATLAB, Super Decision and Excel software. According to the final map, the lands of Ardabil city have been classified into five groups with very high, high, medium, high and very low priorities for choosing the right place to use green space. In order to match the results obtained from the model presented in the urban green space survey with the facts available in the study area, it's land use map has been prepared in GIS environment and the results of the model mentioned in the land use map have been announced. The combined use of ANP model and GIS in prioritizing and determining the best places in the city to determine uses is the innovation of this research.

Ashoori street, with a length of about 2100 meter in the center of the area A of the city of Bushehr. that in terms of organizing a place - space, user, urban, etc. has a large number of user-annoying and polluting urban. The type of research the applications - development industry, and the method of doing it, is as a descriptive - analytical and harvest for field and check the list of jobs. In this research, the first all guilds pollutants and disturb the segmentation, then the type of pollution and can have it has been set. Also assess the quantitative and qualitative related to it, have been doing that for quantitative and qualitative assessment of the degree of compatibility and incompatibility, and also evaluating the desirability of neighbourhood, each user is designated. The causes of this mess should be mainly on the weakness of the management, lack of implementation of laws and regulations search. The results of the survey, quantification, showed that 28 types of user annoying and polluting city that their number amounted to The 60 units,there is enabled, in the Ashoori street. In the qualitative analysis of the user available also with the use of Arc GIS software, etc. density user annoying and also according to the indicators of the qualitative assessment, the results indicate that the user, in terms of the compatibility, far fairly consistent, and in the desirability matrix of its conditions are relatively unfavorable

The changes in the natural sub-system are mainly due to human activities and land use changes. In order to prevent the degradation of valuable lands, it should provide the necessary framework by using landscape development and forecasting for decision makers and urban-regional decision makings using landscape development and forecasting. The central city- region of Mazandaran province, is one of the geographical boundaries of Iran, which has undergone many changes recently due to unbalanced physical-physical development. In this research, we attempt to simulate the land use development and scenarios prediction in 1420 to reduce the effects of unbalanced development on a region of natural value. To achieve this, the SLEUTH model has been used to simulate future land use and scenario. The data and information required for the study include slope, land cover, exclusion, urban development, transportation, hillshade, which were extracted from the SLEUTH model and its five growth coefficients. Finally, it was revealed that the trend of development in the northern and central parts of the city- region was formed more than other areas and the best scenario in achieving balanced development of the region is a multi-centered network.

Land-use change is one the most prominent problems which should be addressed by planners and decision makers. As this problem deals with a large set of data and variables, application of advanced techniques and computer-based methods for prediction and simulation of land-use change is inevitable. For this reason, various methods have been developed to obviate the underlying complexity of land-use changes. Due to the uncertainty of land-use change process, competitive essence of land types for occupying vacant lands and lack of these items in the structure of the existing models, this paper aimed at developing a model based on cellular automata (for representing dynamics of the change process), fuzzy logic (for representing uncertainty and probability underpinning land use change phenomenon) and Monte Carlo approach (for representing spatial competition) to make more satisfactory results than previous conventional CA-based models. Therefore, in this paper, firstly, a flexible framework of the proposed model (IMCFA) is completely described and the process of land use change is mathematically expressed. Then, the model is calibrated and implemented on the study area together with FCA and conventional CA for simulation of two pre-defined scenarios in two time periods, 2012-2022 and 2022-2032. Finally, three indicators (compactness, compatibility and land suitability) are measured on the outputs of the models to make modelling assessment process possible. The results showed that for our defined problem, IMCFA generated more satisfactory results than FCA and conventional CA. Moreover, FCA represented more acceptable outputs than conventional CA according to the above mentioned indicators.

Nowdays, Metropolitan areas are confronted with various ecological challenges due to their heterogeneous and demographic growth and as a result, They suffer from many environmental challenges and social or economic problems.Therefor, the necessity and importance of paying attention to sustainable development theory and its emerging aprroaches such as livability and Eco-city pattern, which can reduce the mentioned problems are felt more than ever. Using Eco-city pattern, The livability aproach can provide a city that is free from none-biogical problems, human-oriented and livable for all segments of society. This study is conducted to evaluate the livbility of Tabriz metropolis using Eco-city pattern and it is applied in term of its purpose as a descriptive analytic type of study.Information and research data were prepared and arranged by using a questionnaire tool and five-choice questions of Likert spectrum have been arranged.Sample size was determind by using Cochran formula with a 3% error rate of 1068 and by considering the density of households in each of the 10 regions of Tabriz randomly distributed and collected.Data analysis was performed using SPSS and LISREL software based on structural equations and FUZZY multivariate analysis in GIS environment. Based on the results , The Tabriz metropolis in attributes derived from Eco-city studies,the average of 330.21 and a standard deviation of 44.63 has moderate livability.The imbalance is evident in the tens of districts.Outcomes and statistical analyzes indicate that the areas where urban management has been able to implement its urban plans have a better livability.

Today, cities are considered one of the main tourist destinations for tourists, and tour planners, and therefore, cities such as Tehran as the national capital with many attractions need to plan a way to develop urban tourism as a guide and urban tourism. Or it can be used as a strategic tool to enhance sustainable development of cities. The development of urban tourism or "road tourism" can be developed as a tool for sustainable urban development. This method has been used in a quantitative-analytical way and the data collection method and the required data have been culled in the form of ideas and surveys (of the type based on brainstorming interviews). The analytical technique of Meta-Swat has been used for comparative analysis; fuzzy rankings were performed with fuzzy and subsequently comparative methods and the results of the two methods were analyzed comparatively.

The purpose of this study is the role of Election Advertisement in vandalism murals in public spaces of Khorramabad and also methods of control and counteraction. The method of the present research is descriptive-analytical and based on documentary and survey studies. In order to study the subject more closely, the statistical population of the study includes the population of Khorramabad according to the 2016 census (373,416) which has 3 districts, 23 districts and 77 urban neighborhoods and the sample size using Cochran's formula is 384 people based on sampling. Clusters were done. Cronbach's alpha coefficient (0.839) was used to assess the reliability and a survey of urban experts was used to validate the questionnaire The study of the role of election campaigns in vandalism graffiti is an innovation of this research.To assess the effects of vandalism in the city using questionnaires completed by urban experts; The ELECTERE model ranked the most important vandalism factors in the city.The results of the research showed that the most graffiti that caused the loss of citizens' rights and also damaged the urban furniture was related to the Election Advertisement of the candidates of this city and other vandalistic graffiti had the lowest amount. According to surveys, more than 58.33% of the murals in Khorramabad are related to the candidates' Election.
