利用Landsat—5 TM4、3、5假彩色合成图像,对地形、土壤复杂的杭州市西湖区进行了1:5万土壤解译制图。结果表明,TM图像的土壤可解译率达到96％;解译图斑的准确率为88.5％;与土壤普查成果图比较,总图斑数增加25.5％、图斑吻合率达到84.9%。图斑纠正率为26.3％。因此作者认为,可以用TM资料进行1:5万土壤解译与制图,更新县级中比例尺土壤普查图。 Using Landsat-5 TM4,3,5 false color composite image, 1: 50000 soil interpretations were made on the topographic and soil complex in the West Lake of Hangzhou. The results showed that the soil image interpretation rate of TM image reached 96%, the accuracy of interpretation map patch was 88.5%. Compared with the results of soil survey, the total number of spots increased by 25.5% and the coincidence rate reached 84.9%. Chart correction rate was 26.3%. Therefore, the author believes that 1: 50000 soil interpretation and mapping can be done with TM data, and the scale survey map of soil at the county level can be updated.
