| 摘 要： | 基于TM卫星影像的基础上，应用ERDAS和ArcGIS软件，对影像原始数据进行了去除噪声、TM4，3，2三个波段假色彩合成及与spot卫星影像在坐标配准的基础上的融合等一系列预处理。并进行图像的监督分类、绿地的提取，由此得出重庆市都市区的绿地状况特征：城市总体绿地率低，绿地分布不均，长江两岸的覆盖率低。并对改善城市绿地状况提出了建议。

| Abstract: | A series of pre-processing including clearing up noises for image original data,composing false color of 3 wave bands in TM4,3,2,integrating spot satellite image on the basis of coordinate correction by using software of ERDAS & ArcGIS in the view of TM satellite images are operated.The greenland characteristics of Chongqing city are concluded as low greenland rate of city on the whole,unbalanced greenland distribution,low forest coverage on both sides of Changjiang river.Based on these,suggestions on improving urban greenland situation are put forward. |
