Tabriz city in East Azarbaijan province also has a high potential in terms of having natural attractions and suitable climatic conditions. In this research, in order to evaluate the suitability of a suitable ecotourism location using the Analytical Hierarchy Process (AHP) and using the method (OWa) and Geographical Information System (GIS) were first examined according to the situation of the study area and the opinions of nature tourism experts and the evaluation of effective options in evaluating the spatial suitability of ecotourism development and all the options were converted into information layers and finally Using the AHP FUZZY technique with the OWA method in the GIS environment with the combination of 16 layers of information, the spatial compatibility map of the ecotourism development of the study area was prepared. Based on the results obtained from the spatial suitability map of ecotourism development in the study area, 52493.8 hectares or in other words 23.48% of the area is at a very favorable level, 50017.8 hectares or 22.38% of the study area is favorable and 1 51709/ or in other words 23/13 is at the average level. Also, the results of this research showed that the most unsuitable areas for the development of ecotourism include 24659.3 or in other words 11.03% of the entire area. The central region of Tabriz has a high potential for ecotourism. This area is in a very favorable condition in terms of research criteria. Thus, in terms of the most important criteria, i.e. distance from natural landscapes, distance from historical, religious and ancient attractions, and distance from facilities and services, due to its proximity to neighboring cities, including Tabriz itself, as the capital of the province, it has a good status compared to other parts of Tabriz city.

Soil erosion is a serious problem, due to progressive arid condition and incorrect management on the eastern slopes of Sahand Mt. Many parameters are aggravating soil erosion in this study area and in catchment scale. Soil is under intensive water erosion as a semi arid area on the slopes of Sahand (NW of Iran).The traces of this erosion has become apparent with the shapes of surface disturbances and gullies and rills in agricultural and grazing lands. In order to investigate causes and factors of water erosion and defining risky lands, we used USLE model and GIS techniques. In this article water erosion and susceptible land erosion, were analyzed using topographic factors, landuse, and precipitation and soil type. The results of study suggested that length and gradient of slope is play important role in erosion processes. In study area, the pattern and type of erosion is defined by length. In some parts of the area where length of slope is increased, depth of gullies is also increased. In addition, when silt composition is increased, linear erosion is also aggravated. The zoning map shows that slopes toward flood plains have very high potential for water erosion.
