摘　　要：景观格局空间变化及其廊道效应是景观生态学研究的基础和热点之一。以汶川县桃关地区为例,应用遥感与GIS技术,探讨了地震前后高山峡谷山区河流廊道的景观格局空间变化及其廊道效应研究的方法。利用高精度卫片/航片对汶川地区景观分布信息进行了提取和分类,准确地对山区廊道景观格局的过去和现状进行了对比分析,为山区居民经济发展和居住地址的合理规划提供有力的理论依据。The spatial changes of landscape pattern and its corridor effect have been a basic and hot issues of landscape ecology.This paper discussed the methods how to research landscape pattern space change and their effect by RS and GIS in Taoguan area of Wenchuan County before and after earthquack disaster,and also extracted the information about the distribution of landscape,then contrasted the landscape pattern of the past and the present situation,this provided a strong theoretical basis for rational planning ...
