Spatial Information Quantitative Analysis Method on Integrated Assessment and Monitoring of Ecological Environment
生态环境综合评价与动态监测的空间信息定量分析方法及应用

This paper summarized remote sensing and geographic information system based spatial information quantitative analysis method of integrated assessment and monitoring of ecological environment.The study aims at to monitor the environmental changes that caused by the regional development activities using remote sensing and GIS.Considering those effects of many ecological environment factors,spatial overlay analysis is necessary and integrated assessment result is hoped.After these,the digital environmental model to calculate the integrated environmental index by means of making the factors system,special subjects'data overlay analysis was established by the author.This index shows the environmental situation and finds its changes in a period.The conclusions show the environment index in 1991 and 1995 respectively,and the dynamic changes of environment situation from 1990 to 1995.
