| 摘 要： | 城市绿地作为城市结构中的主要元素,在城市中起着一个重要的作用。本文基于TM遥感影像,对大连市城市绿地专题信息进行提取,并对绿地格局进行研究和探讨。通过计算各组成分分量和归一化植被指数ND-VI之间的相关系数来进行波段组合,提高了遥感影像的分类精度。结果显示该方法可以准确地得到绿地信息。

| Abstract: | As a main element of urban structure,urban greenbelt plays an important role in the city.Based on TM image,a method of extraction of greenbelt information is developed and a pattern of the greenbelt in Dalian is discussed in this paper.By computing the correlation coefficient between NDⅥ and other combined bands,the bands combination is finished and the accuracy of classification is improved.The result indicates that this approach could derive greenbelt information from this method exactly. |
