Increasing population has disrupted the order of nature and led to restructuring of the original land. In recent years, in order to prevent the horizontal growth of cities, the idea of constructing high-rise buildings in cities around the world such as Tehran metropolis has been proposed. One of the negative impacts of high-rise building is the change in urban wind flow. Therefore, this study aims to assess the impact of high-rise buildings on the performance of urban wind flow using an inductive-comparative method. In this study, District 22 in Tehran was selected as the case study due to its increasing trend of high-rise construction. The findings of the study showed that the natural pattern of wind flow changed due to the incorrect and non-normative positioning of tall buildings; thereby, this led to the secondary effects resulted from stagnation or intensification of wind flow causing serious problems for air inlet corridor of Tehran. Therefore, appropriate principles and criteria for both the site location as well as the assessment of high-rise building observed by urban managers seem to provide bases for accurate management actions and reduce the side effects.

Leisure space today is one of the important areas of urban studies as the quality of how leisure time is spent has become more important. This comparative study was done to both measure satisfaction indicators of leisure time and to investigate the factors influencing leisure space satisfaction in two districts in Maragheh. In order to collect the data in this study, questionnaire surveys were conducted. The statistical population of the study were citizens living in District 1 and 4 in Maragheh and the population size in each area was determined based on Cochran formula. The questionnaires were then distributed in the leisure places by using simple-random sampling method. In order to analyze the research data, both descriptive and inferential statistics were applied by means of SPSS software. The results of the study showed that there was a significant difference in leisure space satisfaction between Districts 1 and 4. Additionally, it was determined by factor analysis that the leisure facilities, variety of leisure places, and access to them (with 38.9 percent variance) in District 1 and also the facilities and variety of leisure places as well as their cultural functions (with 38.7 percent variance) in District 4 have played the most important role in shaping the residents' satisfaction of their leisure space.

The purpose of the current research was to identify the components of urban sustainability in the city of Likk, of the provinces of Kohgiloyeh and Boyer Ahmad, using a descriptive-analytical method. First, 36 indicators in 4 environmental, economic, social and physical dimensions of urban sustainability were determined by using documents and opinions of 23 experts in the relevant field. In order to rank the factors, AHP and Expert Choice software were used. In the present study, the inconsistency rate of all pairwise comparisons was less than 0.1. Therefore, the consistency of the comparison matrix is acceptable. The innovation of the current research was to identify the indicators of sustainability in a small city with a geographical location and specific customs and culture, and to apply quantitative and qualitative criteria simultaneously and score and prioritize them. The findings showed that economic factors, environmental, physical, and social factors were important. Among the components or sub-criteria, income status and employment percentage were considered as the most important factors affecting urban sustainability. Therefore, the indicators of sustainability and their degree of importance in small cities are affected by the economic, social, environmental and physical conditions of those societies. Unbalanced growth of urbanization with inadequate urban infrastructure and lack of sufficient job opportunities cause urban instability. The process of sustainability is a multi-dimensional flow that should be avoided while paying attention to the improvement of the economic situation and the creation of public welfare, the destruction of resources, the destruction of the environment and social anomalies.

The purpose of this study was to assess the qualitative components affecting the security of urban thoroughfares in the central roads of Hamedan and the method for so doing was descriptive-analytical. A researcher-made questionnaire was used to collect research data. The reliability of the instrument was confirmed by Cronbach's alpha test with a coefficient of 0.74. The statistical population was shopkeepers and passers-by in the area. Due to the uncertainty of the number of the study population, 384 people were determined as the sample size using the Cochran uncertain statistical population formula. The study of security in the streets of Hamadan is a subject that has no background and its results are complementary to the previous studies that Izadi and Haghi have dealt with in Imam Square of Hamadan.The results showed that Bouali Street has the highest security compared to the other five passages. In this street, activity and land use with 0.87 operating load was the highest position. Other streets in terms of security conditions were Shariati Street (activity and land use with 0.72), Takhti Street (activity and land use with 0.66), Babataher Street (activity and land use with 0.63), Shohada Street (role of social supervision with 0.48) and Ekbatan Street (role of readability with 0.42). The results indicated that the factor of activity and land use had the greatest impact on the security of urban roads in Hamedan.

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

Based on the statistical evidence, The Earth's climate is warming and it happened particularly in the urban areas. For example, the annual average temperature in Iran's third largest pollution metropolitan-Karaj, during the period 1960 to 2008 increased about 2.256 degrees Celsius. The heating effect on the human environment has more features and derived urban heat island becomes more severe and lead to increasing air pollution in urban environments. Energy consumption increased to create favorable conditions of human living. Generally increasing temperature in urban environments poses serious problems and costs. The only way to prevent or at least mitigate these problems is Change the physical structure of the city in order to adapt the heating suitable place.Due to the high value and low land area of green space in the metropolitan cities,it seems that choosing green roof technology in large cities is a suitable altenative because of improved quality and it,s impact on sustainability of the urban environment. The main objective of this research is to introduce green roofs system and its impact on reducing the heat-island phenomenon. The temperature effect of green roofs in comperative study with other roofs were analyzed on micro climate scale and simulated by using Derob software. The finding is clearly shown that there is considerable reduction in temperature capacity. The results show that impact of heat island can be reduced by developing green roofs in the future constructed buildings in comparison with other roofs.

The main objective of this research is to analyze the security of tourism and to identify the unsafe places of tourism in increasing the attraction of tourists to Hamedan province in 2016. The research method used in this study is descriptive statistics and geo-statistics techniques. The data of this research is provided through a survey. The statistical population consisted of 80 experts from the tourism companies of Hamedan province. In this research, the sample size was calculated on the basis of Cochrane's statistic and Morgan table. In the most practical manner, 66 experts from tourism firms were calculated. To detect the existence or absence of a spatial structure among the insecure tourist areas, Poison diagram of the variogram or was applied by using the land survey tool in the ARCMAP software. The results indicate that the distribution of unsafe spots is not accidental and not patterned, but they follow the spherical statistical model. Also, the results of the analysis of the research data indicate that there is a significant correlation between security of tourism and security of insecure centers with increasing attraction of tourists, so that Spearman correlation coefficient test is less than 5%.

Ozone gas is one the pollutant that it survey in Isfahan gauge pollution stations. A part of production and diffusion of ozone related to atmosphere parameters directly and indirectly. The aim of this research to study atmosphere parameter affected on surface ozone variations in Isfahan town. The correlation and multiple regression have been used for analyze. The results show that increasing of temperature and sunny hours in three time period; monthly, seasonal and yearly have been directly correlated to increasing of ozone but relative humidity and highest wind flow have inverse correlate with increasing of ozone. For example, the correlation coefficient between average of ozone with daily maximum of humidity, mean daily of temperature and number of sunny hours is R=-0.569, R=+0.533 and R=+0.52 one by one. In the best conditions in Farvardin month, 80.6 percent of variations have been explained by atmosphere parameters. More than 50% of variations of ozone in Lale station in 30.6% of total year have been explicated by atmosphere parameters whereas this percent of explication only in 16.6 percent of total year in Bozorgmehr station have been explicated. Thus the values of ozone in Lale station to be more affected from the atmosphere parameters in compare with Bozorgmehr station.
