Trends of Remote Sensing and Geographic Information System(GIS) Applications on Vegetation Ecology

近年来国外应用遥感和ＧＩＳ技术进行植被研究的最新动态，上述技术与各种生物组织水平模型的集成以及植被和环境的动态监测是当前该领域的热点．同时，简要阐述了我国在这个方面的研究现状．

Vegetation ecology is one of the important fields in ecological studies, and it is always focused by ecologists both from home and abroad. Despite of their rapid developments, remote sensing and Geographic Information System (GIS) technologies are widely used in many areas of vegetation ecology since 1960s, such as vegetation survey, mapping, production estimation, vegetation dynamic monitoring, analysis of vegetationenvironment relationship, and so on. Many remarkable progresses have been achieved up to now. In this paper, some up-to-date studies on application of remote sensing and GIS finished by foreigners are reviewed. The result showed that people paid more attention to the integration of remote sensing, GIS, and models from different levels as well as to the dynamic monitoring of vegetation changes with its environments. In addition, a brief introduction of present-days studies on this field in China is also described.
