3S技术与农林复合生态系统景观格局分析

3S Technique and Analysis of Agri-forestry Ecosystem Landscape Structure

基于3S技术的农林复合生态系统景观格局分析的途径为:以遥感数据为数据源,使用图象处理系统对其进行分类,获取生态系统景观类型图,再以地理信息系统为手段,计算斑块的数目、面积、周长等斑块特征,在此基础上计算各种景观指数,进行生态系统景观格局综合分析。

The routine of analysis of agri-forestry ecology system landscape structure based on 3S technique is: data comes from remote sensing, which is classified by photo disposal system, and the ecosystem landscape photo is produced. Then landscape indexes are calculated and ecosystem landscape structure is analyzed synthetically.
