三峡库区污染源空间数据库建设及应用

Construction and Application of Spatial Database for Pollution Sources in the Three-Gorges Reservoir Area

三峡库区自蓄水以来,富营养化问题突出,污染源监管工作愈发受到关注。本文基于空间建库技术,提出了三峡库区污染源空间数据库的总体设计思路,探讨了空间数据库设计、建库流程等内容。应用实践证明,这种设计提高了空间数据管理效率和展示效果,对其他各地环保信息化的建设都会起到积极的示范作用。

With the increasingly obvious eutrophicationin Three Gorges Reservoir area after impounding water, more importance was attached to Pollution sources monitoring. This paper is based on spatial database technology, put forward the general design idea of spatial database for pollution sources in the Three-Gorges Reservoir area, discusses the design of spatial database and database building process. The application proved that the design improves the spatial data man- agement efficiency and display effect , to other environmental information construction will play a positive role model.
