南丰县红壤资源的遥感调查与分类

THE SURVEY AND CLASSIFICATION OF RED SOIL RESOURCE BY REMOTE SENSING IN NANFENG COUNTY

应用１９９３年１１月５日Ｌａｎｄｓａｔ－ＴＭ的ＣＣＴ磁带，参考ＴＭ的假彩色合成图像，结合地面资料如地貌、土地利用、地质图和土壤普查资料等，通过几何纠正、线性变换、平滑处理、比值分析和假彩色合成等图像自动处理后，采用聚类分析和最小距离法相结合的计算机自动综合分类方法，对南丰县的红壤资源及其类型进行了分类。以实地调查和用土壤普查结果进行验证，此次自动分类的精度分别为９２．６０％和９３．８４％．

Using the CCT tape of TM in 5th September, 1993, and with other data, for example, the topographic map, the geologic map, the land use data and the soil survey data, and so on, the red soil resource in Nanfeng county was surveyed and classified automatically by computer through the comprehensive method of non-monitor and monitor after the TM data was delt with by computer image processing. Compared with the results of example survey and the data of soil survey, the automatical classification accuracy was 92.60% and 93.84%, respectively.
