摘要
This paper describes the design, implementation and applications of theeco-environmental information system in Tianjin City, which is the kernel of the decision support sys-tem for urban eco-environmental regulation (DSSUER) The design of this information system isbased on the analysis of the requirements of users. The system features that it has expendability,maintainability and universality, makes data be shared between different components of DSSUERand provides help facilities and protection. The system is built by using database and graphic basetechnologies it consists of the main control module, data-management module and data-proassingniodule. The applications of this system is demonstrated by an example which is the case ofsuitability analysis of land use for residential areas in Tianjin.
