Rural management has always undergone various changes. Today, this pillar is the responsibility of the rural municipality Foundation. The purpose of forming this institution is to have a strong executive force in order to develop rural areas. rural municipality, as the executor of village programs and projects, has an important role in reducing urban and rural inequalities and improving the development of the village. Determining the degree of success of rural municipality in performing tasks is possible when its performance is carefully measured. The purpose of this study is to assess the performance of rural municipality Foundation in terms of economic, social and environmental indicators in rural areas of Sarbisheh. The research method is descriptive-analytical and based on data collection in the field through a questionnaire. The statistical population of the study consisted of heads of households (1931 households) in 30 villages with rural areas. The sample size at the level of heads of households was calculated using the Cochran's formula of 320 people. The result of one-sample t-test showed that the best performance of rural areas is significantly less than 0.05 in terms of social indicators with an average of 3.78. Also, a significant difference was observed between the studied villages in the field of social indicators with a significant level (0.008), economic indicators with a significant level equal to (0.004) and environmental-physical indicators with a significant level (0.047). In terms of social performance, Dehneh Chah village with an average of 4.43, in terms of economic and environmental performance, Baghestan village with an average of 3.90 and 4.16 are in first place. The study of paired t-test with a significance level of less than 0.05 and an average difference of (-1.271) indicates that the situation of rural development indicators has become more appropriate after the establishment of the rural municipality Foundation.

By assessing the functions and ecosystem services of protected areas, planners and decision-makers of land use planning and sustainable development at the regional and national levels can be of great help. The present study specifically assesses the water and soil resources in the Gandu Protected Area and the economic valuation of these services. In order to model the ecosystem services of water balance, soil conservation and water quality, the hydrological model based on WWPSS remote sensing data was used. The simulation was carried out using a series of one-degree square mosaic images (one hectare) on a monthly scale. The Invest model and the replacement cost method were also used for economic valuation. The results showed that the total water produced in this area is 401,205,344 cubic meters per year. Also, the minimum, maximum and average water budgets are all negative and are equal to -1492.76, -38.04 and -639.24 mm per year respectively, which indicates a lack of rainfall and intense evaporation and transpiration in this region. The average potential pollution of surface water is 4.5% and this region prevents 2 tons per hectare of soil erosion annually. The real economic value of water production and soil conservation is estimated to be 20.18%, 67.54 and 2729.65 billion rials in 2019, respectively, with inflation correction. Three scenarios with discount rates (compound) of 8, 12 and 15% were used in the periods of 5, 10, 15 and 30 years to determine the economic value of the functions of these resources in the future. The results showed that, for example; With a discount rate of 15% and over a period of 30 years, the economic value of the water production and soil conservation functions reaches 4471.82 and 180730.13 billion rials, respectively. In total, the economic value of the water production and soil conservation functions is 0.35 and 14.17 percent of the total value of the region.
