湖泊水质信息系统研究与应用

本文在建立湖泊运动模型，不量平衡模型的基础上，对污染物浓度的扩散进行了计算机模拟并快速形成了符合ＧＩＳ数据结构的空间数据和属性数据；实现了专题自动分类及查询子系统并对武汉市东湖富营养化物质氮，磷和江西赤湖重金属物质铜污染进行了计算机计算实验，达到了实用的要求。

STUDY ON LAKE WATER ENVIRONMENT INFORMATION SYSTEM AND ITS APPLICATION

In this paer,the consistency diffusion of the pollute materials is calculated on basis of the movement model and water balance model. According to the requirement of Geographic Information System(GIS), the spatial data and attribute data are formed quickly. The thematic auto classification and query sub system are complished. This system has been used for the diffusion of N, P in East Lake, Hubei province, and Cu in Chihu, Jiangxi province. The results meet the requirements of application. This is a test of combining Remote Sensing, GIS, Computer graphical technique and environment monitoring technique. Therefore it is very useful for monitoring and processing of lake pollution.
