| 摘 要： | 本文基于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,在城市中心城区,由于人口密度大,建筑物密集,绿地面积较少.

| Abstract: | This paper picks up the thematic information of the greenbelt in Kaifeng by using TM image.By calculating the correlated coefficient of the principal components and NDVI,this paper combines bands so as to improve the precision of the judging image by eyes and classification,and thus acquiring fine result.This paper indicates that the proportion of greenbelt in Kaifeng is 22.56%, and distributing mostly in suburbs. In the center of the city, the proportion of greenbelt is less because of the density of population and buildings. |
