Shows that the inner parts of urban settlements are often worn out and inefficient. The aim of this research is to evaluate the worn-out texture of Chokhorlar neighborhood in the old and inner part of Tabriz city, which was completed by presenting a scenario. The research is of applied type and its method is descriptive, analytical, cross-sectional survey. Information was collected through field studies in the form of questioning, interviews, focused group discussions, and the questionnaires were processed in 11 types, and after coding in SPSS. ArcGIS was used in the physical, spatial and environmental part and preparation of thematic and analytical maps. The statistical population of the entire neighborhood was 148 households.according to Morgan's Table, N =162 residential plots with a sample size of S=115 were selected. Considering the many problems, a total of 65 households answered the questionnaires. Then evaluation was done using SWOT model. Based on this, the score of internal factors (strength and weakness) was 2.29 and the score of external factors (opportunity and threat) was 2.52 which indicates the dominance of weaknesses over strengths in internal factors and the dominance of opportunities over threats in external factors. The innovation of the research is in the design of neighborhood regeneration scenarios. Finally, the third scenario was approved for implementation in the form of a practical strategy with respect to design rules in a traditional context with a traditional and modern integrated desi

The aim of the present study is to identify suitable locations for landfills in Dorud city using GIS system and fuzzy logic. Descriptive-analytical research in the research of the criteria of the Environmental Protection Agency (IEPO) that are considered for this process, including topography, geology and... Using GIS and multi-criteria or fuzzy decision analysis has been used to solve the problem of mechanical landfill system and create a ranking of potential landfill areas. In this method, three steps are used to find suitable places, which include: linear weight combination, fuzzy logic approach and prioritization of potential sites that are ranked by the analytical hierarchical process after installation in the last step. Also, field observations confirm the suitability of the selected sites and therefore this method can be used in urban areas for the method of selecting the waste disposal site. Selected locations are considered to minimize environmental risk and human health problems. Also, the results indicate the application of the geographic information system in the production of the zoning map from the hierarchical analysis process of AHP and based on the zoning map, the best GIS points have been used. Then the field observations also confirm the suitability of the specified areas for landfilling.

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 2020-2050, 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.

Hamedan with a long history in Iranian urban planning, has a relatively large bazaar.Mirzakazem Caravanserai and Golshan sara are among the most important caravanserais in Hamedan, which are important due to their location next to the historic bazaar of Hamedan, the commercial center of cities such as Zanjan, Kurdistan and Kermanshah.Considering the Importance of the Whole of architecture and the creation of living and living spaces, Christopher Alexander's living centers theory explores the pattern of living structures in accordance with the concepts of integrated universality and strong centers in the form of 15 features.This paper responds to the following question with descriptive analytical methodology, qualitative approach and library documents: What is the physical structure of the traditional Hamdan bazaar consistent with Alexander's theory?Many studies have been carried out in various sectors of the traditional bazaar and the concepts of the theory of living centers of Christopher Alexander with 15 features in various topics, including the castle of Gourtan, Iranian garden and Tabriz Rab’e Rashidi have been examined and the physical study of traditional bazaar in the form of concepts of the theory of living centers is a subject that has a history does not have. The results of the research confirm that the traditional Hamedan bazaar is consistent with the characteristics of this theory, and Golshan's camp has the highest symmetry, contradiction, echo, and integrity of the physical life of Mirza Kazem. The comparison of the geometric structure of the buildings and the fifteen characteristics of Alexander's live structures model shows that the role of the centers of strong, intermittent repetition, contradiction, separation of gravity, free space and boundaries in the structure of the buildings is greater.

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.

This study was conducted with the aim of analyzing the distribution pattern of land uses in the district 3 of Ahvaz. Land uses were evaluated at the regional, district and neighborhood levels by calculating indices of Compactness, Herfindahl-Hirschman, Fragmentation, Simpson’s Diversity, Entropy, Built-up Land Density, and analytical tools available in ArcGIS software, including ANN, DD and GWR analyzes. Therefore, this research was done with a practical purpose and a descriptive method, and the data was collected by a library method. It should be mentioned that so far a few articles have been written on the evaluation of the pattern of land use distribution by these methods and also on the case of the district 3 of Ahvaz. The study showed that in the district 3 of Ahvaz city, the existing per capita land uses wer 12 m2 higher than the standard per capita. Zone 2 had the highest density and compactness and zone 3 had the highest dispersion. Despite this, the pattern of distribution of land uses in the zone 3 showed more mixture, diversity, concentration and continuity. Spatial distribution of 46% of land uses was highly clustered and the land use direction towards the center of the district was favorable. This orientation attracted the population in the center of the district. As a result, Land uses in three Ahvaz regions do not have proper distribution and it is necessary to prepare a plan to organize land use.

Women, as half of the urban population, have more specific sensitivities than men about perceptions of crime areas. Therefore, by examining their perspectives on identifying crime potentials at the level of urban spaces, it is possible to achieve the characteristics of a safe urban space from the perspective of the totality of an urban society. Accordingly, addressing the issue of what characteristics of urban open spaces from the perspective of women make them safe or prone to crime, is the main purpose of this study. Also, among the various urban spaces, parks are of special importance as a public place for the daily presence of women, and this factor led to the selection of Shiraz Freedom Park as a case study. The research strategy in this study includes a combination of quantitative and qualitative methods and information was collected through questionnaires, interviews, observation and mental imaging. The results showed that the set of factors affecting the feeling of insecurity in women in urban parks can be classified under four physical, functional, social and perceptual-visual indicators. In these cases, following factors are very important in creating a safe space in urban parks from the perspective of women: vegetation density, the presence of sub-spaces and outcrops, territorial segregation, the presence of signs and symbols, the circadian nature of land uses, proper location of entrances and exits, the possibility of proper navigation in space, artificial care, reputation or a notoriety) a space, gender dominance in parts of the park, visual communication with different parts of the park, proper lighting at night and the brightness and clarity of the space.

The purpose of this study is the feasibility of developing eco-oriented strategies and operational plans for the development of smart transportation systems in Khorramabad city. Descriptive-analytical research method was implemented using survey. The research data collection tool was a researcher-made questionnaire in two stages. The statistical population included managers, responsible specialists and experts in the cargo and passenger transportation management organization of Khorramabad municipality and consultants related to the transportation system, of which 30 people were selected as the sample size. The prioritization of the strategies obtained from the questionnaires was done using the combined method (AHP and ACCEPT) and the QSPM method. The results of these two methods were compared using SPSS software and by calculating Spearman's correlation coefficient, and the coefficient was 0.98. Analyzes related to the combined method (AHP and ACCEPT) were performed using EXPERT CHOICE software and the inconsistency rate for prioritizing goals, development axes and strategies was obtained in all numerical stages smaller than 0.1. SWOT matrix was used to formulate strategies. The innovation of the current research is the use of different software from previous studies and the provision of appropriate strategies and operational plans for the smartening of urban transportation systems. The results of the present study showed that Khorramabad city is in a poor condition in terms of developing smart transportation systems. Regarding the goals of intelligent transportation, priority was obtained with safety, public satisfaction, environmental improvement, and reduction of energy consumption and delay time, respectively. Also, in relation to the six axes of development of intelligent transportation, priority was given to management and organizational policies, financing, human resources, technical infrastructure, cultural environment, and legal matters, respectively.

The purpose of this research is to study the economic role of Mirjaveh border corridors on sustainable urban development dimensions. This research is descriptive-analytic in terms of method and nature, and in terms of purpose it is an applied investigation. SPSS software was used to analyze the data. The statistical population of the present study is the households living in Mirjaveh city, and the sample size was determined using Cochran's formula (324 people). Investigating the four dimensions of sustainable urban development (economic, social, physical and environmental aspects) separately in relation to the economic role of Mirjaveh border corridor is one of the innovations of this research. The results of Chi-square test showed that there is a significant and positive relationship between the economic and social development of Mirjaveh city and the economic role of the border corridor. The results of the multiple regression test showed that the economy of the border corridor significantly predicts physical development. The results of the one-sample T-test indicate the low economic role of the border corridor in the environmental development of Mirjaveh city. Finally, in order to investigate the significant difference between the economic role of the border corridor in terms of development, the statistical process of analysis of variance (ANOVA) was used with the help of the general linear model The results showed that the economic role of border corridors in the social and environmental dimension has a significant difference. The general conclusion of the research shows the impact of the economic role of Mirjaveh border corridor on the dimensions of development (economic, social and physical).

The purpose of this study is to zone flood risk in the city of Maragheh due to floods caused by the inundating of the Sufi Chai River. The criteria being used included the distance from the river, distance from drainage lines, population density, residential density, slope, DEM, aspect, and land use. Based on the experts' opinion and knowledge of the area, 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 0.75 score had the highest value and the land use factor with a coefficient of 0.09 had the lowest value for creating floods, and then all layers were fuzzy in GIS 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 were in the city center along the Sufi Chai River with an area of 3.126 ha. They are located in areas 1, 2 and 3 and districts with low flood risk in the outskirts of the city having an area of 13.595 ha 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.
