A basic rule. of sustainable development is the coorditation among society, economy,resources and environment, which can be indicated by an index system. The coordinated degree is evaluated through modeling analysis; The related information are organized and managed by using spatial database management tecnique to satisfy the querying, editing and maintaining etc..At present, the database in the Pearl River Delta is composed of basic information database; thematic spatial database; image base and statistic database. The applications of the databases in sustainable development are mainly focused on coordinate analysis and multidisciplnary evaluation with the index system of the four subsystems (society, economy, resources and environment) using techniques of DB, GIS, RS.Two case studies respectively on urban sustainable development model and landuse managing and planning model for sustainable development are made.
