in this study, the effects of land use changes with surface temperature of karaj cityand spatial autocorrelation have been discussed using the moran index. for this purpose, landsat OLI- TM satellite imagery has been used in 2000 and 2018. first, the images were taken and the required images were applied. then classification using object orinted method and nearest neighbor algorithm was developed and the earth surface temperature was extracted with split window algorithm (imagery). The results showed that the arid land has the highest temperature in 2000 and 2018, respectively, due to the lack of vegetation, the high capacity of absorption of heat by barren soil, and the use of blue zones in 2000 and 2018 respectively, has a temperature of 38 - 25 (° C), which is دفع and has lower heat temperatures. also, the results showed strong relationship between land use and temperature. finally, the hot and cold clusters of karaj city heat islands were extracted using the hot spots analysis index (hotspot). Space autocorrelation analysis with global Moran's indices showed that the Earth's surface temperature was cluster - like. the analysis of hot spots confirmed the focus and cluster of the heat islands of karaj city in space with increasing periods of time.Keywords

this study aimed to spatially analyze the pattern of land use distribution in District Three of Ahvaz City. This study is applied in terms of purpose and in terms of descriptive method. This study is applied in terms of purpose and descriptive in terms of method. Study Scale includes the study of area, district and neighborhood levels. The method of data collection is document-libraries. To investigate the concentration, density, compactness, composition, continuity, dispersion, orientation and centrality and spatial autocorrelation of compression indices, Hirschman-Herfindahl concentration, Fragmentation, Simpson Diversity index, entropy and Land built density, Nearest Neighbor Analysis, Was used for geographic weight distribution and regression methods in ArcGIS software. The results of the calculations showed that the existing per capita of the land uses is 12 Square meters more than the standard per capita. Zone 2 has the highest density and compaction, while Zone 3 has the lowest density and highest dispersion. However, Zone 3 has more compactness, diversity, concentration and consistency of land uses than other Zones. The distribution of 46% of the land uses was very clustered. The orientation of land uses in the center of the region is desirable and this orientation has attracted population in the center of the region. As a result, the areas of Ahwaz's three District are at different levels in the land use distribution indices, and thus require a local land use planning plan.

The purpose of this study is to analyze the feasibility of land use planning in the Master plan of Malayer city. If the urban development plans are implemented as approved, the public interest will be provided and many urban problems will be solved..In this regard, for the first time the Master plan realization of Malayer as a middle-sized city with a population of about 170,000 people was examined. The research methodology in terms of purpose is applied and of nature is descriptive-analytical.Needed information was extracted from the city's development plans. The results showed that like all comprehensive plans that are prepared in Iran by traditional methods, the comprehensive plan of Malayer city, is accompanied with weaknesses and threats of this model such as authoritarianism, separation of the plan preparation process from the implementation stage, certainty in locating uses, …, and has had little feasibility. Dedicated review of Malayer Comprehensive Plan showed that, in general, The feasibility of the proposed uses has been low. In the meantime, the uses of urban facilities and equipment, health-welfare, sports, hospitality and tourism services have been below the average. Educational, administrative and disciplinary uses, green space and forest parks, industrial, religious and transportation facilities have been constructed more than moderate and need and only residential, medical, commercial and cultural uses have been realized in accordance with the master plan proposals. In the meantime, the irregular increase in the level and per capita industrial and roads uses have caused more damage to the city of Malayer.

The purpose of this study is spatial analysis of the resilience of 22 neighborhoods of Babolsar in terms of physical indicators. The research method is descriptive-analytical. For this purpose, Shanol entropy model was used to weigh the indices and VIKOR multi-characteristic decision model (VIKOR) was used to analyze and level the studied areas according to physical resilience. What distinguishes the present study from previous researches is that in the present work, the degree of resilience of different textures of Babolsar city has been studied and analyzed according to physical characteristics (based on land use within the texture). According to the research findings, 40% of Babolsar neighborhoods show resilient, 20% semi - resilient and 40% low resilience in terms of physical indicators. The final evaluation showed that by emphasizing land use in case of emergencies, the physical resilience can facilitate service delivery and reduce potential damages, while 60% of Babolsar neighborhoods are not resilient in this regard.

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. Then, using related research and researchers' opinions, the three scenarios of historical trends, protection of lands with natural value and multicenter network were evaluated.The results showed that the coefficient of expansion and gravity of the road have the greatest impact on simulation and scenario building and play a very effective role in the future development of the study area. Therefore, around the main communication axes of the study area, the pattern of linear scattered development, in the vicinity of villages and populated towns, the pattern of cluster development and in other lands with a separate structure, the pattern of scattered development and frog jumping have a spatial appearance. This development trend has been formed in the northern and central areas of the city-Mazandaran region more than other areas and the alternative scenario in order to achieve a balanced and balanced development model of the region is a multicenter network. The innovation of the research in simulating the development of constructed lands and the scenario of development developments in the city-central region of Mazandaran province is the prediction of lands constructed based on the SLEUTH model.

In the sustainable development, the physical aspects of man-made areas are of great importance. This paper, in order to quantify the growth pattern of human-made areas, the relationship of built-up areas of Golestan province with ground surface temperature using six landmarks including number of patches, largest patch index, shape index, nearest Euclidean distance, aggregation and Cohen examines. The selection of measures should be based on criteria such as independence between the measures. Statistical analysis of correlation between measures showed that there was no correlation between them. Landscape measurements were extracted by using Fragstats software. The results of Landscape analysis also showed that Gorgan city has the highest homogeneous structure and Maraveh Tepe city has the most inappropriate human-made structure. Landscape ecology studies are based on the importance of spatial structure on ecological processes. For this purpose, the statistical relationship between the structure and surface temperature of the earth was investigated using Pearson correlation coefficient. Surface temperature data were also extracted from the Madis sensor data. The results showed that there was a significant relationship between the shape of the structure and the surface temperature. The man-made areas have a more complex shape and the surface temperature of these areas is higher than in other areas.

One of the main concerns of city planners and managers is how to fairly distribute and allocate urban resources and services in different areas of cities in proportion to the needs of urban society. Optimum distribution of services are directly related to the planning of land use and the successful planning of urban land use, in turn, depends on how the laws and aropriate policies create and employ efficient methods to provide and implement urban projects as well as land use plans. This study aimed to investigate how the urban resources and services were allocated and concentrated in different areas of Shahindezh city with an emphasis on social justice. The research method was analytical-comparative while using statistical techniques as well as practical models including Williamson index and Shannon Entropy. The findings of this study indicated that the majority of urban land use in Shahindezh was under common standards of the country that according to lack of space, it could be used for cultural, religious, and sanitary purposes. The results also revealed the unfair and unequal distribution of a number of activities and services in different areas of the city. Finally, investigating the spatial distribution of urban services indicated that there was a tendency towards concentration and polarization in land use in some areas of the city.

Urban open spaces are invaluable assets in maintaining ecological health in a highly developed urban matrix. Unfortunately, habitat values and ecological quality of these areas are often challenged by consecutive urbanization. The assessment of changing structure and function of an urban space system is crucial in maintaining livable cities. General characteristics and type of open spaces are investigated in case study – Mashhad city. The possible impacts of urban landscape change on the ecological qualities of natural open space patches are explored by using a landscape structure indicator. Even though various conceptual and analytical approaches exist in measuring the ecological integrity of natural systems, in this paper specifically deals with isolation issues. Because an isolated open space system loses its ecological integrity, isolation index yields meaningful result for anticipating the possible threats generated by urban structure. Isolation trends of urban open spaces are displayed. Also, numbers yielded by the isolation index presented. GIS seems to be an appropriate tool to evaluate the intricate attributes involved in the phenomenon. Black- white and colored aerial photographs of the city of Mashhad in various date and other data are available are used for the analysis in GIS environment. The results show some eye-opening facts with regards to the planning and management of urban open spaces, and possible threats to the ecological viability of theses precious areas in the future.
