Reports of the World Tourism Organization indicate that tourism has become one of the largest industries in the world. What is important in tourism is its role not only in economic issues such as employment and profitability, but also in urban sustainable development. Moreover, tourism plays an important role in answering on one of the most important needs of human, which is the need to security, mental peace, recreation and entertainment that can be meet by going to the natural environment and spending some times there. In this context, the present research is aimed to identify zones with high potential for tourism in Abardeh rural district of Mashhad city, a region which has high tourism potential. The research method was descriptive– analytical with the practical aim which was performed by using documentary and survey data.Also, Analytical Hierarchy Process (AHP) was used to analyze data. Therefore, factors affecting zoning were gathered by using the Delphi method, and the variables were weighted based on the AHP method using Expert Choice software. At the end of this research, layers were integrated based on the weight of each criterion in GIS software by using overlay functions, and the value of each zone was obtained based on the all effective factors ,and also their weight, and all zones were then divided into three groups namely areas with high, medium and low potentials. The results showed that just 15% of the existing lands in Abardeh rural district have high tourism potential. So, for promotion tourism in this region, it is necessary to suggest tourist attraction land uses based on the potential of each zone.

Tehran as the largest city in Iran, is one of the most polluted cities in the world, so necessity of accurate detection of contaminants and identifying contaminated areas for reducing their severity is obvious. The aim of this research was prepared Tehran air pollution map and determining the areas with the highest polluted. For studying air pollution situation in Tehran, after gathering concentration of 5 main Atmospheric pollutants (CO, NOx، SOx، O3، PM25) from 20 air pollutant recorder station, three Interpolation methods in ArcGIS software include: Kriging, radial basis function RBF and inverse distance weighted IWD have been used. In Additon, for comparing methods and selecting the best of them, root- mean- square error RMSE and the correlation coefficient R2 had been used. It determined that in most of parameters IDW had better accuracy for zoning pollution of the area by checking the RMSE values. For achieving results with using mentioned methods, map of air quality limits in the area was ready and by combining five maps and weighing them into each parameter, general pollution map of the area was prepared. Results showed that in Monoxide carbon pollution zoning map, most of the pollution was related to the unhealthy class, in Nitrogen Oxide and Ozone was related to very unhealthy class and in particle matter and sulfur oxide was related to unhealthy class. In final map also most portion was related to unhealthy class. Overlay Masudieh station with 1091 pollution weight had the most pollutants and dangerous weather conditions and Darrus station with 628 pollution weight had better position.
