%X After multi-factor and multi-tiered analysis of the site selection of domestic garbage landfills in small town with a systematic angle of view, a hierarchical structured model of comprehensive evaluation system, which outputs the suitability grade of site selection of domestic garbage landfills, was established. Taking small towns in Chongqing as object of study, collected data were analyzed utilizing ArcCatalog and ArcMap software on the premise of regional combined and centralized treatment mode with a region radius of 22.2 km. Data analyses include figure digitization, key area extraction, cache analysis, topographical suitability assessment and geological disaster analysis. Influencing factor layers and key areas were also computed by repeated addition. As a result, a distribution map of small-town domestic landfills in Chongqing was drawn so as to provide reference and scientific basis for policy making.
