This study examines two important geographic footprint in layer management and sustainable urban development and urban planning.Methods of collecting and gathering information from the library, field work and questionnaires were used. This descriptive study, explain and through the geography footprint (ecological) for determining the safety of the urban population ) District 13 ( . The results show that the ecological footprint area of 1.913 hectares per person per year, This means that this area 1.376 times more than their share of ecologically sustainable capacity allocated The results of this study corroborates the notion that their needs for sustainable security in the region 13 to meet the needs of other regions is Tehran And the other regional development patterns, according to calculations by Gini coefficients of inequality and relative entropy and Shannon somewhat scattered and uneven distribution of population in urban areas it is evident.

Today, the relationship between architectural climate and design for building structures and solar radiation is quite evident. Therefore, optimization of these structures during the warm and cold years will reduce energy consumption and increase productivity. In this regard, the present study tries to investigate the radiation conditions in Hamedan to optimize the building in hot weather with the lowest energy intake and in cold weather with the highest solar energy. In order to achieve this goal and calculating the solar radiation intensity on the vertical surfaces of buildings in Hamedan, using Excel software, the computational method was calculated by Cisco Stevenson, and the effective temperature calculations were used to distinguish between cold and hot periods. The results showed that the special geographical position of Hamedan, including its placement in the western half of the country, its coldness and its proximity to the Zagros-Alvand mountain range, has caused the need for energy in most months of the year (except in the summer and middle of the day) The sun is high. Also, the results indicate that the most suitable direction for the view of one-way buildings is to the south with a deviation of 15 degrees eastward and west. For the two-way buildings, the north-south direction is the ideal direction, because 18.6% of the sun's energy is related to the warm year and 81.4% of the cold year's energy. In four-sided buildings, especially class and apartment complexes, there are +75, 105, +165 and -15 best ones. In this regard, 29.5 percent of the solar energy is related to the warm year and 70.5 percent of the energy to the cold season

Integrated development, in the sense of comprehensive approach to the logical integrity of spatial-temporal connections between sectors in environmental, economic, social, and physical planning procedures, emphasizes in fect, on the active participation of the people and unified management of areas. In addition, it focuses on the effective interaction between rural and urban areas, as otherwise it would be neither in favor of rural centers nor supporting urban centers. So, despite its outstanding capabilities, the Sarwabad’s spatial system was unable to achieve the goals of a desirable and integrated rural-urban development, lacking unified structural-functional planning. This article deals with the Sarwabad Area (including two cities of Sarwabad and Oraman-Takht and villages of the area). With regard to the integrated approach to rural-urban development, based on a comprehensive empirical field research, the paper has pursued the analysis and definition of the constraints of rural-urban development. The results show that, although there is a direct and significant relation between socio-cultural and physical-spatial indices, the security, economic and physical-ecological variables have the lowest correlation and the spatial flows have a medium link with the characteristics of integrated development. Therefore, As a result, integrated rural-urban development, as expected, has not been materialized.

Abstract The purpose of this research is to explain the entrepreneurial capabilities in the rural area of Sabalan. In this regard, we study the dimensions and characteristics of sustainable development of rural areas, entrepreneurship and its principles and methods in the villages of the region. Finally, considering the capabilities Creating employment and entrepreneurship in the Sabalan region offers optimal solutions for entrepreneurship in the region, economic development and sustainable development. This research is in terms of its purpose and is descriptive-analytic in terms of its method. Data collection was done using library and field methods (questionnaire). Finally, raw data was analyzed by one-way ANOVA, Spearman correlation coefficient and univariate regression analysis using SPSS22 software. The results of the research indicate that Sabalan rural areas have several entrepreneurial capabilities that include tourism capabilities in the field of ecotourism, religious tourism and sports tourism; the medical geology capabilities of medicinal plants, therapeutic honey and hydrotherapy; mineral resources Such as metal minerals, non-metallic materials and construction materials.

The present study was conducted to investigate, analyze and explain the physical-spatial changes of rural settlements at urban collection Mashhad during the last ten years. The research method in this research is descriptive-analytical and fundamental in terms of purpose. Documentary and field methods have been used to collect information. The sample population is 28 villages of over 20 households in urban collection Mashhad which were selected from different classes of population and different distances with Mashhad city. From 20083 households in sample rural areas, using the Cochran formula, a sample size of 377 households were selected by random sampling method. To test the conceptual model of research and the effect of identified factors on physical-spatial evolution was used with partial least squares technique and using Smart PLS software. According to the results, the coefficients t between the main variables of research were above 2.58, that is, the relationship is significant and direct; In this way, internal indices, adjacent to the metropolis of Mashhad and external factors have a positive and significant effect on the physical and spatial changes of rural settlements. According to the coefficients of the total variable, external factors with a coefficient of 0.947 have the greatest impact and the internal factors of the village have had the least impact on the physical-spatial changes of settlements. The results of spatial analysis and ranking of sample villages with the WASPAS estimation model indicated that the villages of Gorgi-Sofla, Hosseinabad-Ghorghi and Dostabad had the highest level of physical-spatial changes.
