Abstract: In a long period, landfilling is the main way to dispose refuses in China, most of which are disposed by means of simple landfilling and dumping, resulting to a great deal of refuse dumping sites. These dumping sites are not only harmful to surrounding ecological environment, but also threaten the health of around residents.Serious aftermath can be resulted by these refuses polluted with heavy metals in dumping sites because of being disorderly pilled. Therefore, evaluation pollution degree of heavy metal in refuses will be beneficial to perform Environmental Impact Assessment of these dumping sites and put forward measures of pollution protection. In this paper, taking the Three Gorges Reservoir Area as an example, the content of heavy metals, including arsenic, lead, chrome, cadmium and Hg, were determined, and pollution degree for heavy metals in refuses were evaluated by ways of single index and integrated index methods, this providing environment protection strategies in the Three Gorges Region.

Key words: Three Gorges Region, refuse, heavy metal, pollution degree evaluation
