摘　　要：利用Landsat TM遥感影像,在Erdas Imagine 9.2软件的支持下,分析了吉林省长春市Landsat-7影像的光谱特征值以及NDVI、NDBI和NDWI的特征值。参照高程及坡度数据,确定了各类地物的综合阈值。用监督分类和专家分类技术对Landsat TM分类,评价了专家分类方法在大尺度遥感数据分类中的作用。The spectral characteristic value and the variables of NDVI, NDBI and NDWI of Landsat-7 image in Changchun were studied using the Landsat TM remote sensing image with Erdas Imagine9.2 software. The comprehensive threshold of all types of ground objects were determined based on the data of elevation and slope. The Landsat TM was classified by supervised classification and expert classification. The role of expert classification in the classification of large scale remote sensing data was evaluated.
