探讨利用3S技术对小区域生态环境变化的分析方法——以福州大学城周围环境为例

Discuss the Analysis Method of the Small Areas′ Ecological Environment Change Based on 3S Technology——Use the Surrounding Environment of Fuzhou College Town for Example

以福州大学城周边地区为例,探讨了利用“3S”技术对小区域生态环境变化进行综合分析的实用方法.利用从20世纪80年代至今的航空遥感(RS)数据,闽侯大学城周边区域乡界地图,植被覆盖的相关生态环境监测数据,基于全数字作业的遥感与地理信息系统(G IS)一体化技术提取研究区生态环境状况及其变化信息,综合运用“3S”技术,通过对遥感影像的分析,运用环境监测技术,进行大学城周边地区多年生态环境变化规律的研究.

Giving the college town for exampling,there discusses using the 3S technology to synthetically analyze the ecological environment change of small areas. Using the data of remote sensing from eighties to nowadays ,the county boundary map of the areas around the college town,ecological environment monitoring data relating with the plant cover,basing on complete digit tasks,the remote sensing and GIS integration technology abstracts the ecological environment status of study areas and the information of change,uses the 3S technology,and studies the ecological environment change for many years of the areas near the college town.
