In recent decades, the expansion of the population and the speed of the urbanization process have caused many inconsistencies at the level of cities, especially big cities. One of these cases is the excessive increase in the production of urban waste and failure to observe the principles of management and its proper burial. In such a way that how to deal with this issue in urban plans is one of the main concerns in different urban dimensions, especially the environmental aspect. the main goals in the urban area and in order to achieve sustainable development, as well as strengthening the public health of cities and reducing various environmental pollutions, is to find a suitable place for urban wastes in a completely principled and desirable way, for this purpose, different methods and there is a difference in terms of their treatment and executive operations. the purpose of this research is to find the effective factors on locating, as well as finding a suitable place for burying urban waste in the metropolis of Tabriz and investigating the current situation of the city with the daily production of 1200 tons of waste. The studied method in reaching the set goal is analytical-descriptive and using the hierarchical decision-making model AHP,
the parameters affecting the location of the waste landfill, which include geology, slope of the area, urban land use, distance from the surrounding villages, distance from the river, distance from the roads, geology of the area, in the analytical process and layer production Descriptive and raster are evaluated.
The results show that among the factors affecting the location of the waste landfill in Tabriz city, the geological factor is the most valuable and the important areas based on the spectrum of the final map are dark green and often have pastures and crops.

Environmental protection in rural areas is of the necessities in rural development. One of the important issues in rural areas is to find the appropriate landfill site. In this article, in order to assess the proper places for landfill in Lighvan village, corresponding geomorphological factors are provided and analyzed. In evaluating landfill site, GIS software and network analysis process modeling (ANP) are used. Five human-economic key factors of topographicalmorphology, climate-hydrology, soil-vegetation and geology are considered. These factors produce 12 layers of land use, distance from residential areas, and distance from the lines of communication, distance from fault, distance from the river, slope, elevation classes, and direction of slope, climate, soil, vegetation and the lithology. The appropriate landfill site is identified by using the layers and models in Arc Map. Results show that proper places allocate 23.87 and improper places allocate 21.13 percentage of the desired area. By zoning plan, appropriate places in the entire Lighvan village are introduced which can be used in future planning.

Ever growth of population and following of that, increasing of landfills have caused that environmental experts pay attention to it. Understanding of environmental processes require the knowing of ecological relations between life and non-life creatures and nutrient cycle and important cycles such as water cycle and nitrogen cycle. Latexes in produced landfills sometimes persist with heavy metals in many years. Usually heavy metals containing with organic compounds in molecular structure show no severance. Landfill excretion management in suburban areas of large cities such as Tabriz is inevitable. To observe multiplicity layers in landfill excretion we used geographic information system for site selection. Results showed that landfill excretion in Tabriz is none desirable due to the status of groundwater and geological formations and the sense that compost industry to be established in this city.
