This research aims to identify the synoptic patterns of dust generation in Kohgiluyeh and Boyer Ahmad provinces. Therefore, two sets of data including the daily data of dust code 06 from Hamdid stations in the statistical years 2007 to 2017 and the variables of air temperature, geopotential height, sea level pressure, orbital wind, meridian wind, specific humidity, and omega were used as upper atmosphere data. To check the synergism of the dust-generating patterns in the given years, the uneven circulation patterns of the geopotential height of 500 hectopascals in the dusty days of the province were drawn. After determining the days of dust using cluster analysis and integration by the Ward method, 5 patterns were extracted and drawn on the roughness data of peninsular height of 500 hectopascals. The results of this research showed that there is the most significant relationship between the synoptic patterns of the Middle East region and dust events in the province by circulation patterns number 2 and 5 at the level of 500 hectopascals. For a better conclusion of the conditions and factors causing the dust phenomenon in Kohgiluyeh and Boyer Ahmad provinces, maps of average sea level pressure, specific humidity at levels of 1000, 850, and 700 hectopascals, omega (vertical air velocity in the atmosphere) at levels of 1000 and 400 hectopascals, Tavai ( Convergence and divergence of wind) at 500, 700 and 1000 hPa levels and drawing of a jet (river of wind) at 200 hPa level during the rule of each of the models were drawn and analyzed.

It has been a long time since the city became a tool for capital accumulation, and this accumulation with the built environment management has brought about an open competition for the conquest of space in a fundamental and totalitarian manner. For this reason, the interpretation of urban processes in the context of capital has become a leftist discourse which considers the transformation of the conventional accumulation regime as its goal. The main critique of the political economy of space or the current regime of accumulation is based on the problem of the complete transformation of the living of citizens through the artificial environment, which is considered to be the direct space representation. In this regard, this study tries to challenge the accumulation space in District three of Tehran, establish its nature by Grounded theory and conduct semi-structured interviews. The results of the research, which was extracted based on 17 interviews and a review of 37 articles, show that the consequences of capital space at both micro and macro levels have a special tendency towards generalization and universality, and the division of space is evident. In fact, the structure of capital space in the stage of spatial action began with unequal competition for the conquest of space, and its performance is completely dependent on the structure, according to experts.

The North Atlantic region is always exposed to severe storms, which are considered one of the most severe natural hazards in the climate field, and every year they cause serious damage to the economic infrastructure and human casualties in the areas affected by this event. These storms can help in the analysis and crisis management plans of this hazard and land preparation. The development of data collection and data mining technologies enables a more detailed study of this phenomenon. This issue requires the use of simple and efficient methods to investigate the behavior and extract the pattern from the database of this phenomenon. In this research, using spatial statistics methods, the trend of changes in the movement of tropical storms in the North Atlantic Ocean and the identification of their governing patterns in the period of 1995-2015 have been analyzed. The obtained results confirm the cluster pattern governing this phenomenon and that the occurrence of storms are not random events and follow spatial and temporal patterns in the studied area. The pattern of storms has a cluster pattern with the maximum value of the average value of the nearest neighborhood of 0.74 and the minimum value of 0.47. Also, the value of the general Moran index, the highest and the lowest correlation and clustering were calculated in 2006 with an index number of 0.66 and 2009 with an index number of 0.12 respectively, and a map of clusters and non-clusters and hot spots was prepared. With a better understanding of the patterns governing the movement of storms, it is possible to reduce possible damages caused by storms. Based on this, as a suggestion for future research, it is possible to include the effect of other parameters such as temperature, water salinity, and atmospheric general circulation systems, which play a significant role in the distribution of the distribution of the occurrence of storms, in the modeling and data mining of storms and get results closer to reality. Finally, as a useful research, the results of clusters and hot spots can be used in predicting the movement of storms in the future.

The policies and rules based on which cities are governed are influenced by legal and political discourses and can cause political and party conflicts. In the field of legal frameworks, ambiguities governing citizenship rights and planning tend to create inequality, and governance is necessary to ensure stable governance in the process of good urban management. In terms of purpose, this research is of an applied type, which was carried out by descriptive-analytical method and based on library studies and field investigations in the framework of the analytical-case model. Survey techniques, questionnaire tools, and interviews with the Delphi community have been used. The statistical sample size using the available sampling was 27 experts with the purposeful sampling method. In order to analyze the data, SPSS software was used, and Smart PLS software was used to model the structural equations with the partial least squares approach to evaluate the conceptual model of the research. Also, the future research method has been used to explain the key drivers and future scenarios using the structural and cross analysis method. The results of the analysis of the path coefficients related to the studied dimensions show that the justice index has the highest effect, followed by the indicators of responsibility, consensus-oriented, transparency, participation, efficiency and effectiveness, legality, and then accountability, which have the least effect on the urban management structure of Region 20. In the second part, by identifying and analyzing the effective drivers and compiling possible scenarios, from the total of 237 situations governing the scenario page, 132 situations and 55.70% are favorable situations, 64 situations and 27% are in static mode and 41 situations and 17.30% shows the percentage of the critical situation. According to the findings, among the 15 plausible scenarios for the good governance of Shahr-e-Rey, there are 9 scenarios with a favorable situation, which show relatively promising conditions at the local management level.

Evaluation of land ecological capability to achieve the planned objectives according to the IUCN, protected areas must be zoned in the process of evaluation of environmental capabilities. This study was done to determine the ecological capability of Haftad-Gholleh protected area in order to upgrade higher level of conservation to National Park and Biosphere Reserve by compilation of systemic analysis and MCDA methods. In this regard, we used Analytical Network Process (ANP) method by using Super Decisions software, with 11 alternatives, 3 criteria, and 10 sub-criteria. In order to achieve it, 508 environment units in the area were achieved with preparing the map of stable and unstable ecological resources, and socioeconomic resources of the area and its analysis and concluding by GIS (scale 1: 25,000). The maps of ecological potential were prepared by comparing the homogeneous units with the special ecological model of the area, and then, with the integration of units with the same usage, a first base map of zoning and eventually the final zoning map with prioritizing and organizing the primary zones as the units of planning was prepared. The results showed that the percentages of the restricted nature zones, the protected zone, the extensive recreation zone, the concentrated recreation zone, the recovery zone, the other uses zone and the special use zone, also the percentages of the core zone, buffer zone and transition zone are 53.63% (62884.5hectares), 27.10% (31764.42 hectares), 4% (4697.28 hectares), 0.27% (326.04 hectares), 0.10% (114.6 hectares), 14.98% (17565.17 hectares), 15.67%, 39.84 %, and 44.57%, respectively. Accordingly, the Haftad-Gholleh area has the minimum zone required to upgrade to a national park and biosphere reserve

The purpose of this research is to evaluate the state of the city body in order to optimize energy consumption in Rashidiyeh neighborhood of Tabriz. According to its nature, the research method is descriptive-analytical and practical in terms of purpose. The statistical population consists of citizens living in Rashidiyeh neighborhood of Tabriz. The statistical sample size was calculated according to Cochran's formula of 384 people. Examining the results of the sample T-Tech test shows that all three physical indicators of the neighborhood, including mass, passage, and open space indicators, were significant at a level of less than 0.05. In this context, the index of open space with an average of 3.32 is in an average condition, and two indicators of mass and roads are evaluated in poor condition with an average of 2.59 and 2.52, respectively. The reasons for this condition are the lack of installation of building blocks in the direction of wind and light, lack of access to services, improper exterior covering of buildings in order to reduce energy, use of poor quality materials, lack of design of roads for air conditioning in the city, obstruction the view pointed to the sky and residential density. Finally, Pearson's correlation showed that there is a relationship between the physical indicators of the neighborhood in optimizing energy consumption. The highest correlation is related to mass index with open space with a value of (0.785), which is considered a strong relationship.

Clean fresh water is essential to support the human population. Urban planners must create good places for people physically, socially, economically, and environmentally. Traditionally, urban planners have not played a role in city water management. However, planners influence how water is used in cities by shaping the built environment through land use regulations. This study aims to show a significant relationship between urban environment indicators and water consumption to improve urban water protection. Based on this, the influencing factors in water consumption were identified and after forming the equations and optimization in MATLAB software, they were coded and implemented using the method of the crow search algorithm. And for each subcategory, the optimal consumption coefficients were recorded as output. By obtaining the optimal consumption coefficients for each of the indicators, including age, literacy, area, occupation, type of residential use, materials, and block form, it was determined that each of the factors with higher optimal coefficients is closer to the optimal consumption. The results show that urban planners, using planning and design strategies at the neighborhood level and by shaping the built environment and regulating land use, promote the protection of the city's water and affect the way water is consumed in cities. A comprehensive approach to all these categories and the logical connection between them, as well as their comprehensive development is the only reasonable way to deal with water management in cities.

Happiness is a collective concept that encompasses all elements of the city system. This study aims to explain the appropriate model of a happy city for Babol city in the form of appropriate factors and components. The present study is applied in terms of purpose and descriptive-analytical in nature and mixed in terms of method. The statistical population of the study to explain the pattern of creating a happy city is urban science specialists in Babol city, which was selected as a sample using a judgmental method and available to 28 people. The factors and components of the happy city in Babol were determined using the fuzzy Delphi method. The reliability and validity of the fuzzy Delphi questionnaire structure were evaluated with Cronbach's alpha coefficient, combined reliability coefficient and mean extraction variance in Smart PLS 3 software. Then, by path analysis method, has been done structural equation modelling for the model of a happy city in Babol city in Smart PLS 3 software.

One of the propositions for measuring the household's social welfare level is the economic level and the amount of income. Residence is one of the essential aspects of citizen welfare. Since benefiting from a favorable urban view is one of the fundamental rights of citizenship. Therefore, our goal in this research is to prove the hypothesis that the neighborhoods where the citizens have a lower income level do not have a desirable urban view. This research was carried out with a descriptive-analytical method and collected information from reliable sources, using the library method as well as field visits and referring to relevant organizations and finally using a questionnaire. Software such as SPSS and Super decision were used for data analysis, and the model used in this research is the Analytical Network Process (ANP) model. In this research, the relationship between the effective urban spatial structure components in the urban landscape, including visual-qualitative, functional-spatial, semantic-sensory, physical-structural and environmental components, is evaluated with the income level of the local residents. The research results prove the correctness of our hypothesis, and thus, prosperous residential areas have a better urban landscape quality and vice versa. Therefore, according to civil rights laws, urban planners and managers are obliged to improve the quality of the urban landscape in all neighborhoods of the city with the participation of the people, regardless of class levels, so that we do not witness the ecological and social separations that cause the decline of individual well-being and social dignity.
