摘　　要：基于ETM和SPOT图像,采用ERDAS和ARCGIS软件,对原始数据进行几何纠正、假彩色合成等一系列预处理。然后对图像进行监督分类、绿地信息提取,并运用景观软件对南京市区的生态绿地现状进行分析。研究表明:南京市区的绿地率较高,但是分布不均匀。Based on the images of ETM and SPOT, a series of preprocessing such as geometric correction of original data and synthesis of false color has been done by using softwares of ERDAS and ARCGIS. Classifying the images and withdrawing greenland information, the authors have analyzed the present greenland situation of Nan- jing City with Fragstats software. The result shows high greenland rate, but unbalanced greenland distribution.
