摘　　要：森林是陆地上最大的生态系统,是地球表面一种重要的植被类型,它对维持全球生态平衡具有不可替代的作用。森林覆盖变化既包含森林与其它地物类型间的转化,又包括不同森林种类间转化的含义。及时准确获取森林覆盖变化信息,对于碳源估测、实现森林资源可持续经营管理等具有重要意义。本文通过对国内外利用遥感技术开展土地覆盖/利用、森林类型识别和制图方法的研究现状及发展趋势的综述,对森林覆盖变化遥感监测方法研究进展进行了概述,并分析了其研究发展趋势。Forest is the largest land-based ecosystems.It＇s an important vegetation type on the Earth＇s surface.Forest plays an irreplaceable role in the maintenance of the global ecological balance.The change of forest cover not only includes the meaning that forest changes to other class,but also includes the change from one forest species to other forest species.It＇s very useful to duly and accurately gain forest cover change information for carbon source estimation and sustainable management of forest resources.In this paper,the study progress of forest cover change detection methods have been summarized by reviewing on the use of remote sensing technique in the field of land cover/use and forest type identification and forest mapping.At the same time,the study trend of forest cover change monitoring by using remote sensing technique have been presented.
