Application Research With GIS On Site Selecting Of Landfill Of City Life Waste--A Case Study On Wuhu City

With the development of economy, the improvement of people's life and the rapid increasing amount of the population of cities, the problem of waste become more and more important to the sustainable development of cities of every country. There're many ways to deal with the city's life waste at present. Such as set on fire, landfill, and compost etc. As an effective means to deal with the city's waste, landfill is the primary method to deal with the city's waste.Around the sites of landfill the soil, groundwater and atmosphere will be set in potential dangerous environment. The imperilment of an incorrect site of landfill to the environments will be catastrophic in the future. So the sites selecting is very important to the whole construction of landfill.The factors of sites selecting of landfill should be considered more carefully than common sites selecting. Landfill sites selecting is more difficult. The factors should be considered include every aspect of nature, economy and society. So it is very complexity to deal with. A careless omission is easy to lead to a severity result. General sites selecting is to study data and sites exploration. It is difficult to consider the factors entirely due to the complex factors. Even lead to waste a great deal of manpower and material resources.This paper will introduce GIS technique to sites selecting research. The technique of GIS can not only fulfill people's visual expression and space query to geographic information. The more important is the ability to spatial analyzes and simulate. The technique of RS can get timing and veracious data of the earth's surface. RS can provide convenient and veracious data to GIS on the Combination of RS and GIS. Upon the indexes of spatial analyze to be study out the indexes' weightiness of environments affection can be worked out through AHP arithmetic. The objective and quick analysis result can be got from the integration of spatial data and attribute data which GIS can deal with particularly. The research can be divided to data preparation and disposition, spatial analysis and result analysis.There're three alternate sites in the result. One site is the landfill which is using now. This can prove two viewpoints: firstly, the location of the landfill which is using now is reasonable. Secondly, the analysis result on GIS is authentic.This research can provide a new method on the sites selecting of the city's waste disposition at present.
