Abstract
Urban segregation has been a problem of many cities of the world. Many researchers have interested in the urban segregation issues. Urban segregation has strongly concentrated poverty and created underclass. Different types of urban segregation exist, including income and racial or ethnical segregation, and depending on the contextual mechanisms within a city. To understand and plan a better community, urban planners needs to know how to measure the segregation and interpret the results. There have been many developments of segregation measures. Some evolved and some remained unchanged. This paper is studied the most used multigroup measures of residential segregation (8 indicators) in Shiraz city and between different socio-economic groups of it by using of the Segregation Analyzer Software. In general, the results show the occurrence of segregation in the medium amount to the high amount and by the calculated values of 0/7177, 0/5785, 0/5474 – 1, 0/5407, 0/3969, 0/3759, 0/3613, 0/3375 in the city of Shiraz. On the other hand, the use of Hot spots Analysis in the study area shows that the greatest concentrations of the socio-economic high group are in almost near the center of Shiraz city and the northwest of city, and for the socio-economic medium group exists in the west of city. Also there is the greatest concentration of the socio-economic low group in the southwest of Shiraz city.

Abstract
At the moment with regard to geopolitical and geostrategic situation of Iran, the existence of countless underground resources and the formation of ideological state, unfortunately, in urban areas of the country, especially in Ardabil ,because of its proximity to the border of northern and northwestern borders with knowledge of this particular situation, economic and infrastructural projects, Infrastructures and installations have been made without observing and interference of considerations and defense and security arrangements and have become a bare and significant available target for enemy and invading countries. This research aimed to study the vulnerability of Infrastructures Ardabil in terms of passive defense and application - development approach in a descriptive and analytical way using 18 effective indicators in form of 5 components of "Lifeline", "crisis management Centers", "military and police centers", "Urban equipment" and "support centers" in three priorities of strategic, psychological and support destruction. Information gathered in the Super Decision software (network analysis) are weighted, then mapped in GIS environment. The results of the studies show that there are six major hazardous zones under crisis conditions and are prone to injury in the Ardabil that the most important of them are the northeast output of Ardabil (Jahad field leading to Astara gate), the southwest of Ardabil (Sarein station leading to the Basij field toward the Sham Asbi village) and finally the north and northwestern parts of Ardabil (Vahdat square), with the sum of (17% of the total land area of the city) have included the highest vulnerability, due to the poor conditions of the physical characteristics and focus on management, corporate, military and state entities in this regions of the Ardabil city.

Abstract
In recent decates, the subject of quality of living in city and the satisfaction of citizens from their environments has attarced the views the most of researchers and international institutes around the world. Because of its importance, UN to publish a report annually in which different cities around the world ranked and compared through the quality of life. Quality of living talk about different indices and one of its important indices is access to the city services which in turns would decrease some of the city problems such as slums and irregular construction, land speculation and etc. This research tries to analysis the city quality of living according to the standards of services access in cities. So, quality of service access was analysed in objective and subjective sections in old zone of Urmia. The research method is descriptive-analytic and we use questioner, different models such as AHP and network analysis and fuzzy techniques, Pierson coefficient for our study. Results show that satisfaction of city-service access has a very meaningful statistic impact on the subjective factors of quality of living and as it increases more, we have more subjective quality. These results tell planners that key factors would have great impacts and roles on the satisfaction of the life of citizens.

Abstract
The management of land development in the compilation of urban development documents is a very important topic. Failure to pay attention to this necessity, and the course of physical development foreseen for urban areas, make the main goal of the development plan, which improves the quality of housing in urban areas, not being realized. The purpose of this study is to introduce a functional model for land development management in order to guide and manage the urban development flow. To this end, the Land Readjustment Plan (LR) as the selected method of land management in urban areas is introduced and it is possible to perform it in a range of Yazd city. The general research method used in this descriptive-analytic study. The data used in this article collected by the library method as well as the field survey were used and analyzed using ArcGIS software. In this regard, a proposal for the scope of the study was compiled and evaluated before and after the implementation of the plan. The calculation of the distributional index showed that the proposed scheme would give 20% of the profits to the owners in the scope of the study. The conclusion from this study shows that using the Land Readjustment Program as an economic and design tool, planning and redevelopment of undeveloped lands can be done in accordance with urban needs. This planning involves modifying the layout of parts, modifying the network of roads, supplying services and infrastructure of the facility. Thus, the field of realization of urban development plans in these areas was provided. It also provided the basis for the participation of all stakeholder groups through creating the necessary attractions for the groups influencing the implementation of the project.

Abstract
Livability approach is defined as the healthy, safe, suitable and economically accessible urban system that brings about high life quality and is considered as a subset of sustainable development. Although investigating urban livability can be advantageous in identifying deficiencies and taking actions in order to improve livability of the living environment of residents, but unfortunately there has been inadequate considerations about livability theory in Iran. the result, in this study, the livability of Urumia city has been investigated. Firstly, after devising 24 factors in 4 aspects (Physical-Environmental, Economic, Social and Health) this index was evaluated in urban areas by using newly invented model RALSPI with descriptive-analytical approach. Finally, based on this model, the areas were placed within the range of very livable to intolerable, so that District #1 was determined as the best area with livability score of 0.31 and District #2 was determined as the most unlivable area with the score of 0.007. This issue revealed a huge gap between the areas of the city.

Abstract
Estimating and predicting precipitation and achieving its runoff play an important role to correct management and exploitation of basins, management of dams and reservoirs, minimizing the flood damages and droughts, and water resource management, so they are considered by hydrologists. The appropriate performance of intelligent models leads researchers to use them for predicting hydrological phenomena more and more. Therefore, in this study, the Gene Expression Programming (GEP) and Support Vector Regression (SVR) models were used to model monthly precipitation of Nahavand City. In this study, precipitation, temperature, and relative humidity data were used in a 32-year period (from 1983 to 2014). The results showed that the same and good performance of both models (R2= 0.92), but according to different evaluation criteria, GEP model showed a little better performance (RMSE= 0.0478 and 0.0486), while the running GEP model is so easier than the SVM model. Totally, it can be said that GEP model had been suitable for modeling monthly precipitation of Varayeneh station in Nahavand City. Finally, the monthly precipitation was predicted the GEP which showed a decrease in precipitation in compared with previous months.

Abstract
Temporary resettlement of the population after the earthquake is considered as a pivotal element of crisis management. The selection of suitable centers for the establishment of citizens can have a significant role in rescue and rescue services after the earthquake. The purpose of this study was to identify potential spots for the construction of shelters and temporary accommodation of the population during the occurrence of a possible earthquake. This research is applied in terms of its purpose. The method of study is descriptive-analytical and documentary. Firstly, using the Delphi method, 16 main and effective criteria for locating these centers were identified in the framework of six clusters including access to the communication network, natural features, spatial characteristics, consistent uses, risk management and demographic performance. Then, using the experts' opinions and the network analysis process, the final weight of each criterion was determined. The most important parameters in this research are population density indexes, grade 1 arterial pathways, and suitable area. Finally, by combining the layers of all indicators, a map of the temporary population settlements was prepared in Sabzevar city. The results of the research show that the lack of suitable spaces, including parks and open spaces for temporary accommodation of citizens in Sabzevar city, is quite evident. At the same time, the points of the city, which have adequate open spaces and are compatible with the surrounding land uses, have a relatively better potential for deployment. Accordingly, the best places for temporary accommodation of the population after the earthquake in Sabzevar, including the Eram Park in the north, Imam Reza Park and the Football Stadium in Southeastern City, Shahr-e Basi, National Park and Shariati Conservatory in the city center, tourist hostel, Green spaces and sports grounds in the west, and finally technical and vocational schools in the city of Tohid. In order to improve the conditions in the aftermath of the earthquake, some suggestions are presented in this study.

Abstract
Ecotourism, as the leading sector of the tourism industry, relies on utilizing environmental capabilities, and needs proper management decisions. In this context, the identification of ecological and environmental power is the most basic step. This study by considering the middle of the city as the sample of this province due to its ecological superiority and using the hierarchical analysis process, attempts to zon the city based on ecological power using the system Geographic Information (GIS). This zoning is done using 11 indicators. The results indicate that about 78 percent of the city's area is in an appropriate and even better condition for the development of ecotourism, and in contrast, about 23 percent of its area faces limitations for the development of ecotourism. In a general conclusion, it can be admitted that the city of Midian has a variety of sub-climates as it covers a wide range, and, in terms of ecotourism potential, there is a significant difference between sectors and regions of existence has it.

Abstract
In public organizations such as municipalities, the design and deployment of a performance and control assessment system can lead to the proper management of urban managers on the road to achieving goals, tasks, strategies and development plans and urban development, in accordance with the quality, cost and time desired. Therefore, this article attempts to study the satisfaction of urban performance in urban services by using the views of citizens of the city of Farouj. For this assessment, using theoretical studies, 21 types of urban services were selected in three sections: Technical, Public and Cultural Services. At the next stage, the questionnaire was designed based on these services. Then, 400 questionnaires were distributed among the citizens of the case study city. In the next step, 380 questionnaires were completely and correctly collected and entered into SPSS software. Finally, the results of the study were analyzed by statistical tests. The results of the research indicate that the average satisfaction rate of public services in the city of Farouj is 3.53, which can be said that the level of citizens' compliance with this service is in the middle level. The average satisfaction rate of technical services in the city of Farouj has been calculated to be 3.31, and the average satisfaction rate of cultural services in city of Farouj has been calculated to be equal to 3.5. The results of statistical analysis indicate that the level of significance is more than 0.05 in relation to four of the urban services. This means that in terms of the services of sports spaces, the collection and disposal of surface water, the quality of leisure travelers and the respect of the clients, the level of satisfaction of citizens is equal to the average. In relation to two indicators of pedestrian quality and public participation, the mean difference with the statistical test was calculated to be 0.16 and -0.19 respectively, which indicates that the satisfaction of these services is lower than the limit on average. In other indicators, citizens' satisfaction is above average

Abstract
The horizontal and urban growth of the past few generations, due to the dominance of the centralized planning system in the country, has led, in accordance with the principle of village-to-city interconversions, that many villages located around cities have undergone numerous changes and changes in the indicator status Of development. These changes, in addition to having positive aspects in most cases, have had a negative impact on the sustainable development of rural areas located in the vicinity of these cities. In the current applied research, a quantitative and qualitative approach with a spatial and descriptive-analytic approach has been carried out. The main objective of this research is to identify the consequences of the Marivan Creep phenomenon on the changes in the development status of the surrounding villages, Over the last few decades, physical development has been speeding up. Data gathering in the theoretical part of the documentary and in the field was conducted by a survey method based on an interview with the local people and the locals to identify the outcomes, and then the classical distribution of the questionnaire among the studied villages and simple random among 203 households supervised by The Cochran formula was determined by volume, 30 from local development experts and observers of the status quo, in order to generalize the findings from the interviews. The results of analyzing the data with the fundamental theory of the technique in the qualitative section and the single-sample t-test in the quantitative section showed that the urban creep phenomenon, in addition to limited positive consequences in improving the physical condition, caused social deficiencies, failure Economic problems, inadequate visual quality, natural environment degradation and institutional management failures in the development of villages studied.

Abstract
In recent years with the development of cities coatings of the Earth's has changed surface. These changes have caused some urban areas to have a few degrees higher than the surrounding temperature. This phenomenon is known as thermal islands. Mashhad is one of the major metropolises in Iran with the problem of thermal islands. Various parameters affect the formation of thermal islands in this city that should be considered. In this study TM, ETM+ and OLI images were used to obtain surface temperature over the period 1987-2016. The study of temporal variations in surface temperature showed that in the studied period, thermal islands were transferred from outside the city to the city. The model for describing the temperature of the surface of the earth has changed and has diminished from the temperature of the city's moderate and cool temperatures, and in contrast, the amount of high temperatures (thermal islands) has increased significantly. The TOPSIS method was also used to obtain the thermal forming factors. 13 natural and human factors affecting the formation of thermal islands were identified. Each expert opinion factor was used to determine the degree of importance. According to experts, the distance from the sanctuary with a weight of %234 and traffic of %155 is the most important and the height with a weight of %022 is least important in the formation of thermal islands. The final results obtained from this model showed that the factors affecting the formation of thermal islands are well recognized and the temperature decreases with these factors.

Abstract
A city is a vibrant, dynamic, and evolving phenomenon that grows and spreads over time and space, and is exhausted and degraded.It also faces crises such as natural hazards and artifacts, resulting from human relationships and physical elements, on the one hand, and social, economic, cultural, geographical, political, and historical conditions on the other. The deteriorated urban fabric, which has physical, functional and operational deterioration, are resistant to the above-mentioned crises and has low vulnerability. Therefore, the need of intervening in these fabrics is crucial for balancing, coordinating the foundations of social life, and improving the urban structure. In this regard, in this research, priority is given to the dimension of resilient deteriorated urban fabric based on a disaster resilience of place model which is one of the models of urban resilience measurement. This research is a descriptive-analytical according to method and is developmental-applied research in terms of the purpose. Also, Expert Choice software and AHP model are used to analyze the collected data by using a questionnaire. The results of the research indicate that, in three macro areas of Karaj, Hesarak and Mehrshahr, the physical-environmental resilience dimension has the highest weight and organizational-institutional resilience has the least weight. Overall, regarding prioritization of resilience dimensions, criteria and indicators, an increasing per capita of vital use in study areas, changing the economic structure of residents, as well as increasing the skill and coherence of citizens to deal with hazards and crises are important.

Abstract
Industrial revolution and its resulting changes have led to urban horizontal growing. Environmental pollution, more energy consumption, development without planning, Increased spending on infrastructure, particularly in the area of urban construction are the consequences of the urban horizontal growing. To remedy the crisis, efforts have been made to recognize patterns of urban development and the realization of sustainable urban form. Meanwhile, the compact city strategy was presented to solve the proposed problems. Compact city is an urban strategy to tackle the problem of sporadic and uncontrolled physical growth of cities. This study aimed to identify the obstacles to the realization of compact city strategy in the central part of Sari. The research method is qualitative on the basis of a theoretical approach. Data was collected in two ways of documentation and semi-structured interviews. The sample included people involved in urban development projects. Purposeful sampling was done using the snowball technique and finally 10 specialists in the research area were selected as the study sample. Results suggest that the presence of monuments, low interest of investors for construction, and inefficient transport system were among the obstacles of the realization of compact city strategy in the research area

Abstract
The rapid expansion of cities and their uneven physical growth, so-called "urban creep", have corrupted the villages and their surrounding lands, causing irregular conversion of agricultural lands and degradation of environmental resources. This situation has also been widespread in Shahrekord, the capital of Chaharmahal and Bakhtiari province. The purpose of this descriptive-survey research is to determine the physical developments of rural settlements around Shahrekord with emphasis on urban sprwal. The statistical population is household heads of rural areas (15000 people). Using the Krejcie and Morgan table, 400 individuals were selected. The tool used is a researcher-made questionnaire on three dimensions of economic, social, cultural and environmental physical consequences. Data were analyzed using one-sample t-test and Friedman test. The results show that the consequences of urban sprawl are respectively environmental-physical consequences (3/98), economic consequences (3/96) and socio-cultural consequences (3/89 (. The most important environmental-physical consequences are increased environmental pollution, destruction of traditional architecture, destruction of biodiversity; major economic consequences of stock markets and rising land and housing prices, diminishing villagers' reluctance to productive activities (agriculture and livestock), capital flight from villages And their savings in the city and the rising cost of living amidst the socio-cultural consequences of luxury and the tendency to consume luxury goods, reduce solidarity and participation, crowding and crowding in cities, modeling of life and urbanization culture. have been.
