This research presents an integration of fuzzy logic with GIS for landfill site selection in Durood city alongside with the customized GIS application for doing this study. One of the most important issues of sanitary landfill is to identify suitable locations. Landfill selection in an area is a critical issue in the decision making process because of its great impact on the economy, ecology and the environmental health of the region. most common sub-criteria, documented in literature and implicated (IEPO) including surface water, ground water, land use, distance to well, soil type, slope, protected area, fault in environmental group, residential area, road, airport, village, infrastructure, historical area, wind direction in socioeconomical group were selected and the weight of each criterion was determined based on expert’s knowledge with use of analytical hierarchy process (AHP). At the first step, in order to find the suitable sites, GIS digital map overlay techniques were used (customized GIS application). The second step was a fuzzy logic approach that the system ranked sites on a scale of 0–100%, with 100% being the most appropriate one. At the third step the potential sites that were selected from the last step will be ranked by Analytical Hierarchy Process (AHP) in order to prioritize the potential sites. Field observations also confirmed suitability of the selected sites, and hence this method can be used in urban areas for waste dumping site selection procedure. Selected sites are considered to be suitable for landfill to minimize environmental risk and human health problems.

The aim of this study is simulation and forecasting of maximum temperature and heat waves in Urmia city from 2020 to 2050 in order to predict and reduce the negative effects of a sudden increase in temperature, which is simulated using SDSM software and CanESM2 model And is predicted using the most appropriate RCP scenario for the next 31 years. For this purpose, the maximum daily temperature data of Urmia from 1961 to 2005 were obtained from the Meteorological Organization and forecasted. The innovation of this study is using the least error RCP scenario for more accurate prediction. According to the results, RCP 8.5 scenario was selected as the least error scenario for forecasting. According to the results the average maximum temperature in Urmia will decrease from late winter to late spring compared to the base period and in mid-summer there will be a slight increase. In general, during the years 2050-2020, the maximum temperature trend of Urmia will be increasing. According to the results of the Baldi index, The heat waves will be short and maximum four days. One-day heat waves will have the highest frequency and will have a slight upward trend, Two, three and four day heat waves will have a decreasing trend. In general, short-term heat waves are more likely to occur than long-term heat waves. Also, since the detected heat waves often showed the highest frequency in autumn and winter, so the probability of this hazard occurring in cold seasons is higher than warm seasons.

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.

Women make up almost half of the population living in cities. However, the issue of securing these segments at the community level is always a major challenge for architects and urban planners. One of the urban places that are used by urban dwellers in urban areas is the city's urban parks. Therefore, the present study aimed at identifying factors affecting women's insecurity in urban parks, seeking solutions to this problem and improving the conditions of such places. The results show that the effective factors in women's unsafe feeling in urban parks are categorized into, physical, Functional, social and perceptual-visual indicators. These factors includes vegetation density, spatial diversity, existence of extraneous and peripheral spaces, division of territory, proper furniture layout, being 24 hours use, proper entrance and exit location, proper routing in space, artificial care, the fame of a space, gender domination in parts of the park, visual communication with different parts of the park, proper lighting at night, brightness and clarity of space in the minds of people and the existence of physical safety in the park. The above items are a set of factors that can affect women's sense of security or insecurity towards the city park.

Failure to develop environmentally friendly strategies and operational plans for smart urban transport systems in Khorramabad has created many problems in using urban transportation systems. Therefore, a comprehensive, well-structured, coherent and operational plan must be launched for it. In the present study, a suitable operational plan for smart urban transport systems using PIP model is presented And SWOT matrix is used to formulate strategies In order to prioritize strategies, the combination of AHP decision criteria techniques with ACCEPT method and QSPM method was used. The results of these two methods were compared using SPSS software and Spearman correlation coefficient was calculated. And a value of 0.981 was obtained, which indicates the closeness of the results of these two methods; Combined method analyzes (AHP and ACCEPT) were performed using EXPERT CHOICE software, and incompatibility rates for prioritizing goals, development axes, and strategies were lower than 0.1 in all numerical steps; Therefore, in all priorities, the inconsistency is acceptableRegarding the major transport goals, priority was given to safety, public satisfaction, environmental improvement and reduction of energy consumption and latency, respectively (or transport delay).With regard to the six axes of development, it has been identified that priority is given to management and organizational policies, finance, human resources, technical infrastructure, cultural environment and legal matters, and the development of intelligent systems is based on this priority.

The growing population and development of cities along rivers in the area of canals and their blockage have created flood-prone areas and increased the damage caused by it. The purpose of this study is to zoning flood risk in the city of Maragheh . have been used criteria, the distance from the river, distance from drainage lines, population density, residential density, slope, dem, aspect, land use. the layers were weighted by network analysis Process (ANP) method using Super Decisions software. According to the coefficients obtained in the ANP model, the waterway factor with a coefficient of 0/7500 had the highest value and the land use factor with a coefficient of 0/0895 had the lowest value for creating floods, and then all layers were fuzzy in GIS environment and with weight Hanging the layers and combining them by gamma method, the final flood zoning plan was prepared. Based on the results, areas with very high flood risk in the city center along the Sufi Chai River with an area of 3/126 hectares. They are located in areas 1, 2 and 3 and areas with low flood risk in the outskirts of the city with an area of 13/595 hectares in areas 5 and 7, respectively. The results from integration of ANP and Fuzzy models, as approved in previuos studies, indicate their high efficiency in identifying the areas with high flood risk. Therefore, it is essential to consider the zoning layers in planinig proceses, particularly rsik assessment
