Knowing natural and human potentials of each area makes it possible for the development planning to be done based on the current situation and its potential. Typical tourism areas of the country are one of the key issues in policy making and tourism development, where attracting private sector investment, will provide sustainable regional development. The aim of this study is choosing a touristic area between the three regions Khranq, Saryazd and Narin Castle in Yazd province. The data was collected using documentaries and field research and data collection tool is a questionnaire with simple random sampling. In this study, to select and prioritize the tourism area, ANP (Analytic Network Process) of multi-criteria decision making techniques were used. Results obtained from AHP analysis showed that, taking into account the environmental criteria, tourism potential, economic potential and the role and impact of weight management, Mehriz Saryazd area is more adequate than the other two regions for investments in Yazd province. Narin Castle is second by a small margin. Also according to the technique used in the prioritization and the results, the pattern can be used for planning for the areas of other provinces. 

The impact of tourism on urban structures and spaces has led tourism to be of particular importance to urban management, and suggests to city managers that improving the quality of these spaces and creating suitable facilities for tourists such as residential centers, recreation areas, and the provision of equipment and modern furniture may urban attract visitors to urban public spaces and ultimately attracts tourists. Urban public spaces and the quality of these spaces are one of the most important indicators of sustainable development of urban tourism, the development of which requires more attention, especially that it has a particular impact on the urban economy and targets the improvement of the economic situation of citizens. The 4th district of Tehran, which is the subject of this study, consists of the view of the Alborz mountain range and green areas such as the valleys of the Lar and Latian dam and the green valleys of Fasham, Oshan and Meigoon, and the recreational sports areas of Darband, Shemshak and Abalei in the east of the Tehran metropolitan area. This area is one of the most populous, most migratory and most resource-intensive areas that because of the largest protected area (Lavizan Forest Park) is distinguished from other parts of Tehran. Sustainable economic development of urban tourism is one of the tools for improving the quality of life of citizens and improving the environmental space of this applied area, which requires appropriate tourism facilities for leisure time and developing tourism. This research is a descriptive-analytic study used to collect data using field and documentary methods. Data were analyzed by T-test, ANOVA and Tukey tests using SPSS software. The results of the research show that the studied area has a relatively stable economic sustainability. Also, the results of one-way ANOVA and Tukey's test show that the price is the most important factor affecting the sustainable economic development of tourism.

 One of the factors influencing human life, health and well-being, especially the factors that should be considered in tourism, is climate. Climate and tourism have a great deal to do with each other, so that having favorable climate conditions is considered as a potential advantage for tourism, and most travelers are mindful of the location and time of travel to the climatic conditions. The expression of the climate of comfort is usually expressed by indicators in which a set of meteorological, human and environmental elements are involved. These indicators present climate data in a way that reflects the response of individuals to climatic conditions, and in numerical categorization, range from very appropriate to very inappropriate. These indicators facilitate the interpretation of the complex effects of atmospheric elements on human comfort and make it possible to compare different places from an ecological point of view. In this paper, using the statistics of synoptic stations in Kurdistan province, human health conditions have been analyzed based on bioclimatic indexes (stress, effective temperature, CPI index and THI index), and the results are as follows: Months May, June, August and September have a very favorable climate, and the months of July and October have relatively favorable conditions for tourist planning and utilization in the province. In general, the best time to travel to West Azerbaijan is spring and summer, as well as the most unfavorable the tourism programs in this province.
