摘　　要：通过对MSS数字图像的分类解译图与全野外调绘的土地利用现状图的系统抽样对比及野外验证结果的分析,对于在地形、地块破碎的南方丘陵,山地使用该图像进行土地分类的精度、存在问题和实用价值作出评价,提出了改进方法。采用光谱学分析与地学分析相结合的方法,建立地理控制系统,编制透明地理要素底图,制定解译规则,以对图像自动分类图进行解译制图。利用成数点抽样数学模型,对两图抽样对比结果进行面积修正和精度评定的模拟计算。由此,提出了将遥感与地理信息系统、抽样技术相结合的资源与环境监测体系的构想。By contrasting the classificatory interpreted map forming from landsat MSS digital image with systematically sampling of land utilization map that made from aerophotography and field surveyed,and by analysing the results demonstrated in the field, the accuracy,the practicability and the existing problems in land classification using the landsat MSS digital image on hills and mountains with fragmentary land in the south of China were discussed.The spectrographic analysis combined with geographical analysis was applied to establish the geographic control system,to draw the transparent basic map containing geographic elements,and to formulate the interpretation rules,and so that can be interprelation and charting on the auto-sorting image.A simulated calculation for correcting the land area and for evaluating the accuracy of land area from interpreted MSS map has been made by the mathematical models of points sampling in proportion and by sampled results.From these a design of resource and environment monitoring system combining three techniques,remote sensing,geographic information system and sampling,was suggested.
