Abstract
Change in precipitation features is one of climate change outcome. Change in precipitation amount, especially in warm season, may influences climato-environmental phenomenon as well as human activity. In current research the decadal changes of monthly precipitation over the Caspian coast of Iran territory was evaluated. Accordingly, a large number of rain gauge stations (385 stations), where rainfall is measured painstakingly, have been used. these stations are under the supervision of Meteorological Organization of the country and Ministry of Energy. Since the original dataset pertaining to the precipitation prior to 1966 had noticeable missing values, and the data after 2016 were not accessible, a continuous time period from January 1966 to December 2016 was selected. From the daily precipitation of aforementioned stations contour maps were created using an ordinary Kriging method. The spatial resolution of these precipitation maps was 3 km * 3 km. Our finding showed that during the under investigation period the maximum gradient of precipitation moved from coastal parts toward mountainous area. Decrease in the area with high precipitation and increase in the low precipitation area is an other prominent decadal characteristics. According to the previous study, these changes might attributed to changes in systems which effect precipitation in the Caspian coast of Iran (northward movement in polar vortex, sub-tropical high pressure and cyclone truck). In addition, increasing temperature trends in the summer tend to decrease temperature spatial differences. Therefore, the convectional precipitation during summer has been decreased.

Abstract
It is important to examine the effect of the tourist personality on the choice of tourist destination. In the meantime, using Hofstede's cultural model in analyzing the effect of tourist personality dimensions on the intention to visit through the perceived homogeneity variable greatly helps to understand this issue. In this research, the effects of femininity, masculinity, ambiguity, avoidance of individualism and collectivism on the intention to visit have been analyzed. This research is applied in terms of purpose and methodological in addition to descriptive and survey research. In this regard, 384 questionnaires were distributed among tourists from German, Japanese, French, Arab (Iraqi), Italian, Austrian, Chinese nationalities residing in five star hotels in Tehran. Structural equation index was used for data analysis. The results show that tourists prefer brands that match their perception of the destination brand. The findings of the study indicate that the personality dimensions of the tourist intent through the popularity of tourism destinations and the image of tourist destinations influence on the perceived homogeneity of the urban tourism brand and the masculinity of the tourism city brand; Perceived homogeneity of urban tourism brand is effective and femininity of tourism city brand does not affect perceived homogeneity of urban tourism brand. The results of this study indicate that Tehran has a masculine brand and people are selected to be masculine and to be collectivist and ambiguous. In fact, the results of the study showed that in selecting tourism markets for Tehran, one should look for tourism markets that are characteristic of the Hofstede model in terms of masculinity, ambiguity and collectivism, as well as the development of tourism spaces for women.

Abstract
In recent years, one of the main approaches to rural development and increasing the well-being of rural households is the development of rural tourism. Because tourism development can play an important role in the well-being of households as well as in rural livelihoods. The aim of this study was to investigate the effects of tourism on improving the welfare of coastal villages in Chabahar. The present research is a descriptive-analytical approach. The statistical population of rural households is Chabahar (N = 3720). Using Cochran formula and quota sampling method, 280 households in 6 coastal villages with tourist attractions are selected as samples. To analyze the data and to answer the research questions, unlimited exploratory co-univariate test, variance analysis and multivariate regression were used. The results showed that in terms of economic welfare indicators, tourism had the most effects on seasonal employment, income growth, housing development, and local economy mobility. In terms of social welfare indicators, tourism has the most impact on improving leisure time, changing lifestyle and lifestyle, developing health facilities, and increasing the sense of belonging to local people. Also, the results showed that tourism in the villages of the study area had significant effects on the economic and social well-being of rural households, but compared with social indicators, tourism had the most impact on economic well-being and its indicators. In line with the findings of the research, suggestions were made regarding the development of rural tourism and the welfare of rural households.

Abstract
Assessment of the land's capacity for urban development in the sense of objectifying the potential of the land is among the expected and executable applications. On the other hand, increasing urban population, followed by the growth of cities, due to the expansion of urban development makes moving toward the principles of sustainable development an indispensable act. Kerman as one of Iran's major cities encountering with limited natural and human development, is not an exception. Thus, it is essential to take into account its development structure. This study aims to identify the fertile lands for future development of the city of Kerman. This study is functional in nature and purpose and descriptive-analytic in methodology. In order to achieve the purpose of the study, the method of fuzzy Analytic Hierarchy Process (AHP) and Boolean was employed, and finally by combination of maps, appropriate lands for future development of Kerman were identified. The results of this study showed that the lands located in South, Southwest, and North and northwest of the city of Kerman are in a better position for future development compared to other parts of the city.

Abstract
The growth and expansion of the dispersed development pattern is one of the ways of settlement development that is shaped by a variety of factors, including urban management policies and approaches. Examine how the development of Tehran's metropolitan area has evolved over the last fifty years and what effective urban management policies and approaches have been and how it has influenced city development. This article deals with it. This research has been used because of the importance of the topic in a descriptive-analytical and practical purpose, based on library and documentary studies and in some cases field observations. In order to achieve the objectives of the study, three types of measurement models were used depending on the subject and variables of the study. In this regard, physical continuity in Tehran urban complex through Shannon entropy model, functional continuity through network analysis model (investigation of habitat and flow points and distribution and land use composition) and poor urban slope growth using Helder model The measurement is located. The findings show that: 1) dispersal phenomena have occurred in Tehran metropolitan area (Helderen and Shannon entropy model), 2) Tehran metropolitan area has been experiencing functional divergence (network analysis) and user distribution The services and services at the Tehran metropolitan level have not been uniform and balanced; and 3) the policies and approaches of urban management in successive years have had wide-ranging effects on spatial dispersal and unbalanced spatial development. Tehran's urban complex had.

Abstract
"Governance" is one of the basic concepts that has attracted the attention of geo-political scientists, and there are contradictory views on this concept, which is one of the main and fundamentally important foundations of the science of geopolitics. The rule of law over higher power and superiority imply that no other legal authority is superior to it. Since the study of sovereignty in political geography is very important, therefore, it is necessary to examine its dimensions and spatial levels. Political geography focuses on the study of phenomena, processes and political currents, and emphasizes their geographic and spatial effects. One of the most important studies in political geography is the study of the country. Each country is made up of three elements of "nation, rule and land".. The linking factor of these three elements is "sovereignty". In political theories, they regard the sovereignty of that government and do not attribute it to any government or government agency alone. At the same time, in no political theory, the notion of sovereignty is not absolute, and it is believed that sovereignty must be exercised within the constitutional framework and in accordance with the law. Land is the space of the state, which, with the spatial scope of the territory, determines the sovereignty of the state, and as the physical container, it includes the body of the political organization. The present article seeks to elaborate on the fact that "sovereignty has different dimensions and levels". The present research is of fundamental type and has been done by descriptive-analytical method. Data collection method is library and computer. Also, data analysis is also qualitative.

Abstract
The national strength of algebraic aggregation is a large number of positive and negative factors that are composed of numerous sources and resources. One of the important sources of national power in the world today and in the post-Cold War period is economic power, which is itself the bedrock of other superstructures, such as political, military, and so on. This research uses descriptive-analytical method and using library resources and field research to answer this question. What are the most important variables and indicators that shape economic power of countries? The findings of the research by examining library documents show that the four main components of economic power including infrastructure, production exchange, production level and financial resources can affect economic power. Meanwhile, 61 variables related to quadruple components were identified. Then, by using the Likert spectrum questionnaire, internal knowledge was measured to measure the importance of each of these variables. Accordingly, economic infrastructure, high-tech exports, food imports and international currency reserves were of high importance. On the other hand, variables such as the share of the poor in the consumption of national income, economic competition, foreign ownership, and commercial costs of violent crimes were of minor importance. Finally, it can be argued that countries have an obligation to take into account the factors and variables in the economic dimension to achieve their national interests and interests.

Abstract
Nowadays, the lack of attachment is a significant point in the construction of towns, which is demonstrated with criteria such as lack of environmental attraction and visual qualities, lack of readability, security, and so on. These factors will affect people's relationship with the environment around them and thus their satisfaction. Golha Town faces numerous problems including lack of space for gatherings, lack of security and space confusion, inadequacy of appearance of the newly constructed buildings in relation to older monuments, and most importantly the existence of empty and unused land. The method used in this research is combinational including a set of descriptive-analytical methods. Data collection is performed using field and documentary methods. The statistical sample of the study was considered to be 384 people, based on the population of Rasht city. By distributing 420 questionnaires, 386 correct questionnaires were answered and returned. Analysis of questionnaires was performed by SPSS software. Measurement of selectivity, permeability and readability was also accomplished using the space syntax method and integration and connectivity analysis on the road adjacent to Golha town. The results showed that the impact of criteria such as readability, security and permeability was moderate. Visual proportions, elemental functions and access have a great effect on increasing the satisfaction of residents. As a result, the use of architectural patterns, considering pausing and moving spaces, creation of management applications, prevention of mass construction and indoor parks, are among the solutions to create the desired increase in satisfaction.

Abstract
International rivers, as borders or crossing national borders, have been considered as a significant part of international relations. Especially, approximately half of the world's population lives within the basin of these rivers, and more than 90% are living in countries with these basins. This condition, by creating an undeniable relationship of interdependence, has made water a critical issue for these countries. Thus, as populations and economies grow and develop and national water resources are exploited for additional growth and development, government action and reaction to a higher share of these transnational sources will increase. By the way, the type of government interaction in line with exploiting these common resources includes a wide range of cooperation to tension and war. In some parts of the world, common water resources in the form of rivers have used as a linking factor between nations and governments. So that, instead of conflict, the beneficiary countries take the path of cooperation and convergence and they have taken important steps with regard to the development of the region as optimal management of common water resources. Although the achievement of international cooperation is a long, lengthy and complex path, always, there are many ways to follow, many steps to take, and many options for appraisal and selection. The current research is a descriptive-analytical research and by means of library resources and examining the practical status of cooperation in a part of the Danube River as a model, concluded that cooperation was not just for water agreements and factors such as environmental concerns, regional security, regional benefits (such as joining organizations and ::union::s), mediation (governments, international organizations, and institutions), etc., are effective in this process.

Abstract
In this Research, the maximum temperature of selected stations in Khuzestan province and the numerical values of 8 extreme climatic indicators belonging to the Expert Team on Climate Change Detection, Monitoring and Indices (ETCCDMI) were used in the statistical period of 1987-2017. To analyze the trend of extreme climatic indices, the Man-Kendall test was used and to estimate the slope of the trend line, the Sen’s estimator was used. In this study, given the importance of global warming that severely affected all aspects of life, the authors explore the relationship between climatic factors and maximum temperature in Khuzestan province until to rely on it, and ones can predict and forecast air temperature at this region. For this purpose, the temperature of selected stations in Khuzestan province and numerical values of 8 climate indicators in the period 1987-2014 have been used. To understand the relationship between climate indicators and maximum temperature at 1 to 12 months of delays, Pearson’s correlation coefficient was used. The results showed that most of the extreme climatic indicators in the study period had a significant trend. The TX10 and TN10 indices have had negative trend in most stations and the TX90, TN90, TXx, TXn, TNx and TNn indices have had positive trend. According to the results of correlation coefficients can be concluded that all studied signals have a significant effect on the province's maximum temperature. The correlation between maximum temperature and indices PNA, TSA, WHWP, WP and NAO, was more than the other climate indicators. Results also showed that the entire indices except NAO have significant positive correlation with maximum temperature of the province. PNA index with a delay of 10 months has the highest positive correlation with maximum temperature of study area.

Abstract
As a novel idea for discussion on the role of industrial development on regional development, the term “cluster” became noteworthy since 90’s in order to increase competitiveness. Territorial development researchers believe that formation of regional industrial clusters improves competitiveness and plays a role in promoting competitive advantages and regional development. Hence, because of the possibility of realization of competitive advantage, Tourism clusters became a focal point for research and policy making. Against this background, the purpose of this research is to analyze and review the role of industrial clusters on development of regional competitiveness and assumes that the higher number of relations in an industrial cluster leads to higher level of regional competitiveness. The research applies descriptive-analytical research method and utilizes questionnaire to collect data. The data was studied by SPSS and Lisrel software packs after approval of validity and reliability of data. Findings corroborate the relation between higher number of relations in industrial clusters with higher level of regional competitiveness and also identifies the contributing factors to development and stimulation of regional development which are ranked by the order of their effect as follows: 1. Social relations, 2. Geographic and location relations, 3. Economic relations, and 4. Institutional relations.
