摘　　要：利用不同时期遥感信息资源，结合实地调查测绘，编制不同时期果林类型图，经过叠合比较，建立动态分类系统，获得果林类型动态日，以此分析淳化县泥河沟流域１９８６～１９９５年果林面积的动态变化与综合效益。Group maps of fruit and nut trees in different stages of growth were success-fully derived from remote sensing-based data and field survey statistics.The dynamic sys-tem of classification was set up with the method of comparative superposition,bringing outanother series of group maps in a dynamic nature,according to which the acreage variationand the overall benefit of fruit and nut production in Nihegou River Valley of Chunha Coun-ty,Shaanxi Province,in the period from 1986 to 1995 were analysed.
