"Cities" are among the phenomena of space that have a special place in geographic studies. Therefore, the interrelationship between politics and space in the city is one of the most important issues studied by political geographers of the present era. To understand these relationships, understanding the natural geography is very effective. In this paper, we try to analyze the geography of the city with emphasis on the typology of cities in terms of climate and location. The question raised here is whether the natural geographic conditions, especially the weather, are effective in the manner and policy of urban executives? In this descriptive-analytical method, this fundamental research studies the climatic conditions of desert, mountainous, coastal cities and their impacts on political, economic, cultural and environmental areas and on the decisions of power holders in general. We seek to answer the question, "How does climate influence the type and manner of policies and policy making of urban managers?" The hypothesis raised in answer to this question is that "natural geographical conditions, especially climate, in the type and method of policies." And policymaking is effective for urban managers. " The results show that the importance of recognizing the existing status of cities and their (natural) geographical location in order to plan well for the future on the one hand, and the importance of scale in achieving development with respect to the importance and necessity of policy making, on the other. That geographic space and policy development are closely linked. "

The people living in rural areas have created special residential fabrics during the time, based on the socio-economic relationships that determine their lives and activities, which in terms of both physical-structural, and various socio-economic functions, are considered as valuable historical-civilization heritage of the country. Recognizing the set of effective forces in the formation of such textures and the factors influencing their structural-functional transformation, opens the way for recognizing the processes of production and formation of social spaces. Therfore, the scientific understanding of such processes, as well as the formation of different types of land use in the process of general socio-economic development, is one of the basic tasks of researchers in space systems, especially of geographers.This article, as a case study, relying on the "strategy of structural-functional dynamics", tries beside the reviewing the main forces and factors affecting the formation of various rural textures in Ardabil region, to evaluate the relationships between differnet land uses and transformation of rural fabrics. The research method in this study was descriptive-analytical and based on the collection of library and field data and information (observation and interview). The results show that the development of texture by changing aspects and dimensions of land use in these villages according to the conditions of the whole country is in line with the transformation of spaces and a kind of orientation towards urban spaces. It is clear that such changes have been accompanied by positive and negative aspects.

Developing entrepreneurship while generating employment and creating incomes can lead to lower unemployment among the villagers. However, in almost the entire world, the factors and drivers that affect entrepreneurship activities vary between men and women, especially in rural areas. The aim of the present study, functional and the method is descriptive-analytic. The instrument for collecting data was a questionnaire and interviews. The statistical population of rural women and men is the Papi section of Khorramabad city (N = 8775). 330 samples (172 males and 158 females) were selected using the Cochran formula. To achieve the research questions, variance analysis, post hoc tests, and binary logistic regression (LM-Newton-Mar card-Raphson method) were used.The results of the research show that there is a significant difference between the factors and factors affecting entrepreneurship development of rural women and men. The entrepreneurship development drivers for rural men (in addition to the economic factor that has been the most important driver of entrepreneurship among women and men) is influenced by infrastructure and institutional factors, while important family and socio-cultural factors The most important drivers of rural women entrepreneurship development. Regarding the results, it is necessary to pay attention to the entrepreneur's gender factor and in order to eliminate the entrepreneurial barriers, taking into account the gender of the entrepreneurs of the strategy and the proportional model, in order to develop entrepreneurship, and especially in rural areas.

In this study we have tried to analyze synoptic - Satellite occurrence of heavy snow in Gilan Province to be paid. To identify patterns of snowfall, rainfall statistics, snow depth and temperature of station daily, during the statistical period (2017-1986) from the National Weather Service provided by Weber index was above the 99th percentile my days with snow depth. The snowfall pattern of January 13, 2008, was determined for snow days in Guilan province using factor analysis (varimax). Then the composite maps of this model were synoptically analyzed and the surface temperature map and NDSI index and its snow cover were satellite analyzed. The results of this study indicate that the main cause of atmospheric disturbances and intensification of high flows of Soudar province of Guilan in this rainfall pattern is the overwhelming sea breeze and vertical upwelling and formation of pilonidal conditions in the lower layer of troposphere. The eastern part of the system is supplied by the Caspian Sea. The reason for the system's persistence in this pattern is a deep ridge with a southwest-northeast direction from Africa to the north of the Caspian Sea and the formation of an Omega type blockage over the Black Sea and Eastern Europe. So in this model the main factor of heavy snowfall in Guilan province is a phenomenon it is not large scale but the main cause of this heavy rainfall is exacerbated by sea breeze and local disturbances due to exacerbated solonidal conditions severe vertical upwelling

Because of the change in demographic structure of cities, it is no longer possible to meet the needs of individuals in the simple ways of the past. During the last decade the growing population of the elderly people in Tehran has led us to meet new needs for services in different areas of the urban environment, especially the adaptation of the urban space with indicators such as security, safety, accessibility, vitality, communication, social participation and ultimately transportation for the elderly. Therefore, measures should be taken by city planners and managers. In this research, survey method was used to collect information on variables and then SPSSwin20 and LISREL8.5 softwares were used for data analysis. The statistical population is the elderly citizens of District three of Tehran that is 71199 people, which makes up about 22% of the residents of this district. In this article, we seek to answer the question of whether elderly people will be provided with urban space justice. In this regard, the results show that the correlations are greater than 0.6 and equal to 1.00. As a result, we end up that the relation of the two variables is direct. In other words, the more urban spatial justice is promoted through the discovery and analysis of appropriate urban strategies for the elderly, the welfare of the elderly will increase rapidly and strongly, and vice versa.

Country divisions are referred to as the process of dividing the country into smaller units, in order to facilitate its administration, distribution of facilities and public services, control over land space and facilitate the exercise of state sovereignty. In other words, every government has the inevitability of managing its territorial territory and exploiting it, boosting the talents and capabilities of the regions, creating favorable conditions for improving the economic, social, political and ... state and security of the country. Divide into smaller units. Based on this, the present study is applied in terms of its purpose and is a survey in terms of its implementation. The information gathering method in this research is a web-based and field-based library method, and a descriptive-analytical survey method has been used in terms of how the results are processed and interpreted and in accordance with the qualitative strategy. Accordingly, the present study seeks to answer the following questions: What are the factors affecting the promotion of levels of country divisions in the cities of Chaharmahal and Bakhtiari? The results indicate that in Chaharmahal and Bakhtiari province, factors such as deprivation and underdevelopment of the region, geographical location and natural status of the province, remoteness and poor access of villagers to service centers and ... have played a role in national divisions.

This study was conducted to investigate the microclimate role of extruded builders in the last decade on surface temperature rise and heat island resonance and air pollution in the Tehran area. Shemiranat station data and Aqdasia air pollution measurement data over a 12 year statistical period were used. Landsat 8 satellite images were used to reveal the role of vegetation reduction on surface temperature. The results showed that in area 1 due to non-regular and unconditional construction in recent decades, the vegetation and trees of the area were not cut or standard green space development was not followed. Two hot areas, or islands of high surface temperature heat, are forming and developing over other adjacent parts. The eastern half of Region 1, especially its southeastern part, boasts a very hot part in all seasons. In hot seasons, surface temperatures in the area can reach as high as 50 degrees Celsius. The middle section is still better off if it still manages to maintain its green space. However, due to the steady growth of builders in the last decade, the minimum (morning) temperatures, especially in cold seasons, are rising rapidly and steeply. The amounts of fine-grained particles, especially PM10 and PM2, are increasing in region 1.The intensification of the heat island has caused south-west to south-southeast winds to intensify all months of the year. And it has made the area particularly polluted in the colder months of the year. The purpose of this study was to investigate the role of changes in land use and deforestation and loss of vegetation in changes in surface temperature and heat island of Tehran metropolitan area.

Shi'ism is one of the main religions of Islam, less events can be studied in Southwest Asia, which is not related to Shiites. Shiites are the agents and agents of events, and sometimes the subject of political-social events . In spite of religious and cultural similarities and common interests, the sects in the present age suffer from components that, as a problem, intensify the process of non-convergence in Shi'a societies and prevent cohesion. Considering the importance of the subject, the author in this paper uses the analytical method, the use of library studies and field studies Assuming: "The political, security, and cultural-social components of the region can affect the Shi'a's lack of convergence," the paper seeks to analyze the factors affecting the Shi'a's lack of convergence in the South West Asia region. Field research findings indicate that the adoption of Shi'a-based policy by regional powers, Salafism and sectarianism, regional power actions and policies, economic and social inequalities, geographical dispersion, territorial disputes, religious and ideological conflicts, And the support of the extreme Shiite movement from divisive actions is one of the most important factors in Shi'a disintegration in the Southwest Asia region.

Natural disasters annually cause an average More than a thousand billion damages to the country. According to experts, Iran is one of the most prone areas of the earthquake and according to official statistics in the last 15 years, 6% of the earthquake casualties were earthquake. In this regard, assessing the seismic vulnerability of different regions of the country in order to reduce the vulnerability of urban communities should be a priority in planning. The purpose of this study was to investigate the role of topography in magnifying seismic effects in the Kalat-Naderi area of Khorasan Razavi province using Pessina et al. In this regard, first, the digital elevation model of sites prone to magnification of geomorphological effects was investigated. These effects included: ridge, peaks, hills, valleys with features such as slope shape, as well as slope and elevation difference. GIS functions were also used to classify critical areas. The resulting maps can be used to assess large-scale topographic areas of risk and earthquake risk. According to the results of the study, out of the total study area, 74.71% were in the range of low magnification, 21.12% in high class and 4.15% in high class.

The phenomenon of climate change has occurred in recent decades as a result of increased greenhouse gas emissions and a general warming of the earth. Which has led to significant changes in the meteorological elements and as a result of the status of water resources in the regions. Short term droughts, large floods, marine hurricanes ... are among the consequences of climate change. The purpose of this study is to investigate the effect of climate change on the runoff of the Caravandr River. In this study, the CORDEX data of the REMO model was used under two RCP4.5 and RCP8.5 scenarios during the baseline period (1365-1384) and the upcoming timeframe (1434-1400). In this research, SDSM and Linear Scaling were used for micromachining of climatic data. The results of the SDSM model showed that there is no acceptable correlation between the Caravander River runoff and the 26 major climate scale parameters (NCEP). Linear scaling method was followed by high correlation between precipitation and runoff and the REMO climatic model showed good performance in simulating climatic parameters. The climate parameters were simulated for the upcoming period (1434-1400) and compared with the observation period (1365-1384). According to the results of this study, it can be said that the runoff of the whole basin has increased in both RCP4.5 and RCP8.5 scenarios in the future time series. The water assessment and planning (WEAP) model was used to study the effect of climate change on water allocation. The results of the WEAP model for three scenarios: increase in agricultural land, industrial progress and population growth indicate an increase in water demand in the catchment area and an increase in unprovched needs for agriculture, drinking and industry in the region.

In recent years, following the main political, economical and social changes, cities and towns have expanded which resulted in lack of sufficient housing and proper lands for urban development. Therefore, governments have always been focusing on housing projects. One of these projects is the social housing designed by governments for the low-income classes. For this purpose, the present research study was carried out with the aim of studying the social housing situation in Eslamshahr and the effective factors, by means of a questionnaire, one-sample t-test and structural equation modeling. The findings demonstrate that the social housing policy couldn’t solve the housing problem of the low-income classes in Eslamshahr and the satisfaction level of the people with the social housing is low. Findings of the study show that social houses in Eslamshahr aren’t in favored conditions. These houses are not well-conditioned in terms of the four criteria of interior construction, safety, environmental situation, and access to municipal services. However, by accurate categorization of the low-income classes, allocation of sufficient and necessary funds, careful studies to choose a place to build the houses, proper design of interior space of the houses, improvement of service providing, and taking environmental factors into consideration, we can take a big step to improve and remove the housing problem of low-income classes in Eslamshahr.

Rural management can be considered planning for the village, organization, developmental action, and coordination and supervision of the work done. Also, the task of rural managers is to investigate the villagers’ needs, shortcomings, planning, and action to participate in the affairs of social, economic, development, etc. Saman County that in spite of the extensive (natural and human) capabilities faced with several problems in connection with the lack of rural, and it may be found in the management style. Therefore, this study aims to investigate and identify the factors, influencing the inefficiency of rural management from the viewpoint of local people. This study is of applied type and its method is descriptive - analytical and based on surveying. The statistics population consisted of all villagers in Saman, and they were firstly selected from among five villages to determine the sample size first by cluster sampling method and then through using the Cochran’s formula, 368 people were chosen to complete questionnaires by random sampling. The collected data were analyzed using spss20 software. The results of the linear regression test showed that the economic factor alone explains 47 % of the rural management inefficiency. The results of the t-test also showed that the socio-cultural dimension (mean 3.21), economic dimension (mean 3.18), and physical-environmental dimension (mean 3.16) had a significant impact on the inefficiency of rural managers performance. In addition, the results showed that in the economic dimension, the budgeting problems in macro level; in the socio-cultural dimension, ethnicity factor and structural failures of the elections; and in environmental dimension, lack of attention to the environment and ignorance of related issues were the most important factors. The results were also showing the place differences in the studied dimensions

In recent decades, important developments have taken place in order to strengthen and improve the relationship between the city and the village and its connection as the most important development tool in the region's sustainable development system. And this connection and connection has been one of the most practical policies of promotion in various environmental, social, economic and residential hierarchical indicators and quantitative and qualitative changes in the context of urban and rural areas. However, Rey city as one of the old, historical, religious, tourism and special geographical conditions of these cities and these characteristics, cause the surrounding growth and transformation of five villages into cities in the last three decades, the background of various developments in the area and the metropolitan area of Tehran. Has been In this article, while evaluating the changes and examining the relations in the regional structure of Rey city and analyzing and analyzing data and field perceptions and using the results of development plans and documents of Tehran province and Rey city, as well as the territory of Tehran, we can The research findings showed that the difference between administrative, political, natural, economic, demographic, lifestyle and behavioral patterns of residents in demanding the type of facilities in rural areas has become obvious and there is no connection. And the same connection between the city and the village, and that we cannot provide the ground for the realization of the above-mentioned plans without looking closely at the surrounding environment. It is necessary to establish laws with a new goal approach in creating integrated management in such areas, which with special conditions, especially being located next to the capital, seems necessary to achieve sustainable development.
