摘要
首先通过全球卫星遥感监测系统的介绍 ,阐述了遥感技术在全球环境数据获取中的重要性。然后概述了遥感技术在土地覆盖、痕量气体、湿地以及地表参数反演等全球变化研究热点问题中的应用及进展情况。遥感技术已渗入到全球变化研究诸多领域 ,成为全球变化研究计划的重要组成部分 ,从辅助手段到主要手段乃至某些问题研究的唯一手段 ,遥感技术发挥着越来越重要的作用。
Firstly, the importance of remote sensing technology in obtaining global envirenmental data is demonstrated by introducing a global satellite-based observing system. Then the application and advancement of remote sensing technology in focal global change problems such as land cover, trace gases, wetlands and land surface parameters are reviewed. Remote sensing technology has been used in many studies of global change and is one important compenent of global change reseach programme. From ancillary to main means and only means in some areas, remote sensing technology takes more and more important role in studies of global change.
