| 中文摘要 |
| 通过建立指标体系、专题数据采集和管理、数字环境模型,提出了一种基于遥感和地理信息系统技术的环境综合评价及其动态监测的定量化研究方法。同时提出利用环境综合指数反映区域环境状况的思路。将此方法应用于西藏中部地区的资源环境监测与综合评价,得到了1990年和1995年2期环境状况综合评价及动态对比结果。 |
| 英文摘要 |
| 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. |
