The present study aimed at assessing tourism potential of a place to meet requirements of sustainable development policies. We studied the Haraz watershed because of its particular environmental characteristics and a high potential for ecotourism. The required data for this descriptive-analytical research were collected by combining field and desktop studies. First, the ecotourism capability assessment of the area was done using Arc GIS 10.3 software based on the Hyrcanian Forest Tourism Development Model for concentrated tourism and extensive tourism. Next, the most important effective indices included (i.e., 19 indices) were determined by Delphi questionnaire and SPSS 17. Finally, AHP technique was applied to analyze the body mass of the indices in order to verify the validity of the model. The results show that 0.0044, 01.3, 3.52, and 37.71% of the study area is suitable for concentrated ecotourism (grade 1), concentrated ecotourism (grade 2), extensive ecotourism (grade 1), and extensive ecotourism (grade 2), respectively. Based on the model applied, slope, direction, and fundamentals (infrastructure) with the body masses of 0.232, 0.116, and 0.115 were identified as the first priorities. Comparing the results of this model and AHP confirms the validity of the model. To strengthen the tourism development potential of the watershed and protect its ecosystems and biodiversity, it is necessary to choose a proper development model. Failure to identify the existing capacities and the field's sensitivities can cause dissatisfaction of local residents and also damage to the ecosystem of the area.

Increasing the efficiency of the electric power industry is extremely important, leading to lower costs, higher profitability, possibility of proper output, efficient use of resources, reduction of pollutants and, ultimately, environmental protection. In this regard, identification of effective indicators for the sustainable operation of thermal power plants is essential, which has the largest share in the country's electricity production and one of the most important air pollutant industries. Using the Sustainable Balanced Score Card (SBSC) technique is a powerful way to design indicators for assessing the organization's sustainability performance (efficiency). The purpose of this research is to identify the effective components on performance evaluation in thermal power plants (with emphasis on air pollution) with respect to the Sustainable Balanced Score Card approach. In this research, the statistical population consisted of experts and managers of Tavanir Company and senior managers of power plants. A questionnaire was used to collect data. The reliability of the results of the questionnaires evaluation was estimated 0.84 using Cronbach's alpha. The results of this research showed that thermal power plants can be evaluated based on Sustainable Balanced Score Card model with five economic indicators (3 criteria), environmental (4 criteria), internal processes (4 criteria), growth and learning (5 criteria), sustainability (2 criteria), and while monitoring of their main processes; it can be identified as efficient units with maximum efficiency and the least pollutants.
