摘　　要：本文以闽江流域为研究对象,以RS为技术手段,借助ERDAS、ArcGIS、EXCEL等处理软件,采用植被指数法,根据像元二分原理,建立用VBIS复合植被指数估算植被覆盖度的模型,生成闽江流域植被覆盖度分级图,并对其格局变化进行分析与评价,揭示出闽江流域植被覆盖的时空变化规律。The paper took Minjiang watershed as research object based on RS with the aid of ERDAS, ArcGIS, EXCEL and so on. It choosed the vegetation index method , according to the the dimidiate pixel principle, builded the model of vegetation coverage estimated by the vegetation index of VBIS, produced the vegetation coverage graduation map of Minjiang watershed , and made the analysis and appraisal to the change of its structure, showed the law of spatial change in the vegetation coverage of Minjiang watershed.
