摘要: 利用航片、假彩色合成卫片对四川三州及西藏东南部地区的土地类型建立解译标志,用此标志和地理比较的综合分析法对一级地类的判出率和判准率达100%;二级地类判准率达100%,判出率达88.5%。勾绘的地类界线位移量均小于0.3毫米,比直接利用地形图的精度高2-3倍,转绘后的面积量算精度亦高。比单独使用地形图或航片进行全野外调绘节省资金20-80%。

Abstract: This paper reports on land resource survey in the west of Sichuan and the southeast of Tibet. The interpretative marks founded by airphoto and false colour satellite photograph with geographical analysis are more rapid and more accurate to the interpretation of the first class land-use types by accuracy of 100% and the second class land-use types by accuracy of 100% than those by the common remote sensing or relief map means. This new method is more suitable and much more economical in the Plateau Regions.
