  Background : Waste is a permanent part of human life. Urban development, increasing use of irresolvable materials and many other achievements of machine life have com to raise one of the main concerns of urban environmental management, that is waste disposal. Waste management in different qualities and quantities is the most important environmental problem.

  Method: The aim of the current study was to determine the Shiraz environmental landfill waste by using hierarchical analysis, fuzzy logic and Geographic Information Systems (GIS) techniques using Expert Choice software . At First, important factors in site selection for solid waste were identified. Then, nineteen layers were digitized and weighted on the basis of the existing standards. The Last ratio that has to be calculated is CR (Consistency Ratio). Generally, if CR is less than 0.1, the judgments are consistent, so the derived weights can be used.

  Result: In this study, using data such as the legal limits of the city, distance from roads, land airport, land use, land capability, artifact effects (rural, urban facilities and equipment, mining ,...), fault, the physical development of the city, surface water, wind direction, population density, soil type, Hypsometric (height floor), slope, vegetation coverage, land types, geology,by different models and maps based on fuzzy logic were used to combine these data.

  Conclusion: After georefrencing the data and models with satellite images a region with 272 hectares in the north of shiraz (19 km away ) with capacity of receiving waste more than 1000 ton per day for 15 yeare, was selected as waste disposal site.
