| 摘 要： | 基于Landsat TM影像,对开封市绿地专题信息进行提取,主要通过计算TM影像及各主成分分量和归一化植被指数 NDVI的相关系数的方法来进行波段组合,提高遥感影像的目视解译精度和分类精度,取得较好结果.研究得出开封市绿地面积占总面积的22.56%,主要集中分布在郊区乡镇.

| Abstract: | This paper picks up the thematic information of the greenbelt in Kaifeng by using TM image. This paper combines bands by calculating the correlation coefficient of the principal components and NDVI. This supplements visual judgement and classification to produce a fine result. This paper indicates that the proportion of greenbelt in Kaifeng is 22.56 %, distribution mostly takes place in suburbs. |
