The elements of value chain were identified and prioritized according to experts in the second part of the paper to measure the relationship between the development of women's entrepreneurship and sustaninable social development through correlation research and strucrural equation modeling. We then discussed the results and the model entrepreneurial development model was developed based on the entrprenrurial value chain with a sustainable social development approach. This model contributes to the formulation of women's entrepreneurial activity and tacilitates the srengths and weaknesses and facilitates. Finally the presentation of the model and the link between the development of women's entrepreneurship of entrepreneurship value chain and sustainable social development were obtained.

This study was designed to investigate the impact of perceived security and perceived value on tourists' spatial attachment. The present study is of applied purpose and of descriptive-analytical method. Libraries and field methods were used to collect the required data and data. The statistical population of the study consisted of tourists coming to Zanjan province. The sample size of the study was estimated to be 384 people using Cochran formula. The reliability of the questionnaire was measured by Cronbach's alpha and the combined reliability coefficient (Cr). The validity of the questionnaire was confirmed by face and expert validity and divergent validity by calculating the mean variance index. SPSS and LISREL were used for data analysis. The results showed that the sense of security and perceived value had a significant and positive effect on tourists' spatial attachment.

Women play an important role in promoting employment and improving the economic situation of society. Therefore, giving them identity and independence and providing the ground for their active participation in various economic and social affairs, especially entrepreneurial activities in urban areas is a very important factor of this great force.
The experts’ demographic features are analyzed. Then the components of entrepreneurship value chain and social sustainable development are sifted out using experts’ opinions (twenty of the best women entrepreneur of Golestan province), Fuzzy Delphi method, and De-fuzzy to find the components of intended variables. Validity and reliability of questionnaires are investigated by Cronbach’s Alpha and normal distribution of components and statistical samples are also analyzed by Kolmogorov-Smirnov and Student’s t-Test. In section one, the prioritization and ranking of dimensions and components of entrepreneurship value chain are addressed (by 198 of women entrepreneur of Golestan province) by using hierarchical analysis process method and Expertchoice software. In section two, to measure the relationships between the developing women’s entrepreneurship according to value chain and the social sustainable development, the Correlational research, the Structural equation for factor analysis test, and Smart pls2 software are used that show a statistical significant. In correlational research not only the relationship between variables are detected but also the type and rate of variables relationship are reachable. The results then are discussed. And the model of developing women’s entrepreneurship according to value chain with the approach of social sustainable development is presented. The model helps adjust the developing women’s entrepreneurship and show the strength and weakness.

By evaluating the functions and ecosystem services of protected areas, it is possible to help planners and decision makers of land management and sustainable development in the region and the country. The present study specifically assesses water and soil resources in the Gando Protected Area and the economic valuation of these services. In order to model the ecosystem services of water balance, soil protection and water quality, a hydrological model -WWPSS- based on RS data was used. The simulation was performed using a series of one-degree square meters (one hectare) on a monthly scale. In order to evaluate the economy, the Invest model and the alternative cost method were used. The results showed that the total water produced in this region is 401,205,344 m³ per year. Also, the minimum, maximum and average water budget of all three are negative and are equal to -1492.76, -38.04 and -639.24 mm per year, respectively, which indicates the lack of rainfall and the intensity of evapotranspiration in this region. The average potential of surface water pollution is 4.5% and this area prevents erosion of 2 tons per hectare per year. The real economic value of water production and soil protection in 2019 with inflation reform of 20.18%, 67.54 and 2729.65 billion rials, respectively, is estimated. Three scenarios with discount rates (combined) of 8, 12 and 15% in 5, 10, 15- and 30-year periods were used to determine the economic value of the functions of these resources. The results showed that for example; With a discount rate of 15% and over a period of 30 years, the economic value of water production and soil protection will reach 4471.82 and 180.730 billion rials, respectively. totally, the economic value of water production and soil protection is 0.35 and 14.17% of the total value of the region.
