摘要
应用遥感技术进行土地覆盖变化监测研究,是全球环境变化研究的重要组成部分。本文归纳了当前土地覆盖遥感监测的主要方法。从遥感图像处理和变化信息提取两方面,对国内外土地覆盖变化遥感研究的现状和最新趋势进行了总结。并对土地覆盖分类的新进展做了总结和介绍。
The study on land cover change detection by using remote sensing technology is one of the most important components in global environment change research. In this article, some research methods on it are summarized and some research advances and current situations are discussed from the image process to the change detection.In the meantime, some research advances on classification methods of land cover based on remote sensing are also introduced.
