摘要
通过对遥感图像的校正、增强、变换和相关性分析等预处理,实现了TM图像的信息提取和精度分析。结果表明,基于TM图像的遥感分析与评价方法能够准确描述城市生态绿地格局在宏观和微观方面的基本特征。
With characteristics of 'synthesis, multi-band and rapid message updating', TM Image has been regarded as a most important technology in the study of resources and environments. Based on an analysis of characteristics of the ecological greenbelt, this paper deals with the ecological greenbelt pattern of such cities as Guangzhou. Studies show that the analytical method based on TM image can depict the basic characteristics of the ecological greenbelt pattern. It is revealed that the greenbelt coefficient of Guangzhou City is very high but the pattern is not balanced. Some suggestions are made with a view to improving the ecological greenbelt of Guangzhou City.
