The present study was aimed to spatially analyze the status of physical resilience in the coastal cities of western Mazandaran province with emphasis on urban regeneration. This research was applied-research in terms of purpose and had a descriptive-analytical nature,. The method of collecting research data was based on the library method and field survey (questionnaire). The statistical population was 382 households in Noor, Nowshahr, Tonekabon, Chalous and Ramsar. For this purpose, one-way t-test, Idas multi-criteria decision making method and multivariate regression test were used.The results of the study according to the general finding of one-way t-test for physical resilience indicate poor resilience of coastal cities in the west of Mazandaran province in peak travel conditions and the favorable situation of the preconditions for urban regeneration in these cities. According to the results of the Idas technique, out of the five cities studied, three cities are in weak groups, i.e. "low resilience status and non-resilience". The results of applying this technique also indicate the unfavorable situation of urban regeneration in three sample cities. The results of multi-nominal regression also show that there are a significant effect of urban regeneration in promoting physical resilience of coastal cities in the west of Mazandaran province.

The present study aims to assess physical resilience, environmental and hazards indicators in the cities of Abadan and Khorramshahr. The research tool was a researcher-made questionnaire that was based on the results of Cronbach's alpha method with minimum reliability coefficient (0.7), approved for each dimension of urban resilience. The statistical population included academicians, experts and institutional - organizational managers. It was based on the Purposive and chain - referral sampling method, through which a total of (106) people who had sufficient knowledge and experience in the field of urban resilience and knowledge of the study area were selected and they were questioned. To analyze the data, SPSS software was used. The innovation of the present study is in presenting and measuring the harmonious indicators of urban resilience based on physical, environmental and hazard dimensions in the cities of Abadan and Khorramshahr. Based on the calculated values for each of the dimensions of urban resilience (environmental, physical - infrastructure and hazards resilience), the results of the study indicate the unstable and unsuitable resilience situation of Abadan and Khorramshahr cities and there is a significant difference between existing and optimal resilience.

The aim of the current research is to evaluate the effects of urbanization on the temporal and spatial changes of climatic parameters and their relationship. Therefore, the impacts of urbanization on minimum and maximum temperature variations were investigated in Iran's Northwestern urban areas. For this purpose, the meteorological (1987-2017) and urbanization data from the general census as well as the housing population (1365-1395) in conjunction with Pearson Correlation-coefficient and Mann-Kendall Test were used. Based on this test, a positive and significant trend was observed at minimum and maximum temperatures among urban stations. The innovation of this article is in the effect of population increase and physical development of cities on the climatic parameters of cities. Decadal changes show the impact of urbanization on climate. The results of the correlation test between minimum and maximum temperature with the number of population in urban areas are positive. The correlation between the minimum temperature in Khalkhal and Khoramdareh (small towns) was 0.8, in Maragheh and Khoy (average cities) 0.7 and Maximum temperature was 0.61 in Mahabad city and there was a significant relationship between the big cities of Ardebil and Zanjan at 0.7, 0.75, but in Urmia and Tabriz (a large and metropolitan city), the population with a minimal temperature was relatively small, but maximum temperatures in both cities with a coefficient of 0.68, 0.61, indicates the significant role played by the urbanization on urban climate. In small and medium-sized towns, significant changes were observed at minimal temperatures. At all stations, the demographic changes and the minimum and maximum temperature increases were observed.There are many changes in the decades of 1375-1385 and 1385-1395.

The purpose of the current research is to investigate and analyze the socio-cultural obstacles to the development of sustainable public transportation in Ahvaz metropolis. The current research is applied and developmental in terms of its purpose, and descriptive and analytical regarding its nature with a survey approach. In order to collect information, two methods of library and field studies (questionnaire and interview).have been used. Cronbach's alpha test was used for the reliability test of the measurement tool, and obtaining a coefficient of 0.95 approves it. The method of analysis was quantitative, which used the TOPSIS multi-criteria decision-making model. Also, the statistical population of the research is made up of the 8 districts of Ahvaz metropolis. In order to determine the sample size of the expert community, the Snowball sampling method was used, based on which 15 experts related to the field of this research were selected. Identifying obstacles to the socio-cultural development of transportation, categorizing obstacles and recognizing spatial differences are among the innovative aspects of this research. The results of the research showed that the socio-cultural barriers to the development of public transportation in the eight regions of Ahvaz are different. In regions 1 to 8, respectively, there exist weak organizational culture, car-oriented lifestyle, weak participation of task units, lack of support for children's travel, irregular boarding and disembarking, resistance to paying expenses. n general, the weak observance of citizens’ rights is the most important obstacle to the development of public transportation in each of the 8 regions.

The purpose of this study is spatial analysis of green space and the best way to reach it in region 1 of Kerman. In this regard, using 4 qualitative evaluation matrices of desirability, compatibility, capacity and dependence )multi-criteria decision making methods) were applied to investigate the spatial distribution of green space uses in District 1 of Kerman. Research data were collected by documentary method with reference to relevant sources and organizations. Each of the four matrix criteria was ranked based on the Inversion hierarchical weight process method and then modeled in the GIS environment and by using analytical functions, a map of suitable locations was prepared to create green spaces in the area. The use of quadratic quality matrix criteria and their weight by inverse hierarchical analysis method along with the design of a geometric network is a way to access urban green spaces and also is one of the innovations of the present study. The results of the present study show total area of existing green spaces in district 1 of the Kerman city is about 54 ha that is insignificant compared with the district 1 the whole area. Based on quadratic quality matrices method, we proposed suitable locations to create new green spaces at about 106 ha. Broadly speaking, the spatial analysis of green space using the method of quadratic quality matrices and hierarchical reversal analysis shows 28. 7% very suitable location, 53. 4% suitable location, and 17. 9% unsuitable location.

The aim of this research is a cooperative evaluation of the urban neighborhoods in district 6 of Tehran based on urban prosperity indicators. Applying urban prosperity in neighborhood planning is a new policy in sustainable urban development. This research based on the method, is descriptive-analytical and in terms of aim is applied. The data collection method was documentary library-based. The WASPAS model was used to rank the neighborhoods and the entropy model was used to weight the indicators. The results of applying the WASPAS decision making model show that there is a difference between the 14 neighborhoods of region 6 than the urban prosperity indexes. The innovation of the research is the use of a comparative and new model in determining and evaluating the indicators of urban prosperity in the urban neighborhoods of Tehran's sixth district.The ranking of neighborhoods in terms of urban prosperity indicated that the three neighborhoods of Yousefabad, Keshavarz and Valiasr had the favorable status with final scores of 0.337, 0.334 and 0.259, respectively, six neighborhoods with average status and five neighborhoods (Nizami Ganjavi, Jihad, Behjat Abad, Fatemi and Jamalzadeh) are in undesirable condition and are at the superiority of urban development planning. The results also showed that the urban prosperity environmental dimension had the most neighborhoods (11 neighborhoods) with undesirable conditions
