土地利用与土地覆盖变化的遥感监测及环境影响研究综述

Review of Researches on Remote Sensing Monitoring and Impact on Environment of Land Use/Cover Change

摘要:

土地利用与土地覆盖变化（LUCC）对全球生态、环境产生了巨大影响，是全球变化的原因之一，也是全球变化研究的重要组成部分。从遥感数据源、遥感分类方法、遥感动态变化监测方法3方面出发，介绍了遥感监测技术在LUCC研究中的应用现状；回顾了LUCC对气候、水文影响的研究进展，并对数值模拟方法在LUCC影响研究中的应用进行了重点评述；探讨了目前LUCC研究工作中在动力机制、对环境的影响、遥感技术及资料应用、多源数据的综合应用及利用区域气候模式进行数值模拟试验等方面存在的问题及未来发展趋势。

Abstract:

Land Use/Cover Change (LUCC) is one of important focuses in global change research and has great influence on the global ecological environment. Some LUCC remote sensing application techniques, such as remote sensing data sources, remote sensing classification and dynamic change monitoring methods, are introduced. The current progress of LUCC's impact on climate and hydrology is reviewed; especially, the application of numerical simulation methods to LUCC research is described. The existing problems and the development trends of LUCC research are discussed in the aspects of dynamic mechanisms, impacts on the environment, remote sensing technology, the composite application of multi-source data, and numerical experiment, etc.
