Solid Waste Management Information System Based on GIS in Chongqing

The large quantity of MSW (municipal solid waste) and ISW (industrial sold waste) piled up in Chongqing has been threatening ecological environment and water resource. Efficient management is the important guarantee of disposing solid waste. This paper describes the data system of Management Information System of the Solid Waste in Chongqing based on the GIS, construction of information database, overall structure, main functions, etc. Integrating related solid waste technology with computer and geographical system, it can provide the reliable, scientific and convenient management and decision-making support of solid waste in Chongqing. The information system, developed by means of Geographical Information System (GIS) on the basis of a great deal of data and graphs of solid waste of Chongqing, includes six sub-systems as follows:data input sub-system;data query sub-system;database management and maintenance sub-system;database of modal management sub-system;application and output sub-system;system management. This system provides friendly and easy operational interface, and plays a significant role in the disposal and management of solid waste in Chongqing.
