对当前植被-气候关系遥感分析研究进行了总结.过去几十年内,全球不同尺度、区域和时间序列的植被变化对气候变化表现出了明显响应.植被的生长变化与气温和降水的变化密切相关.而大尺度上土地覆被类型的变化及植被覆盖的变化对局地及区域的气候产生重要的反馈作用.当前植被-气候关系研究的常用的遥感数据源较多,但也存在单一遥感数据源时间序列局限性问题.多源遥感数据的融合应用是长时间植被-气候关系研究的重要途径.随着遥感技术的不断深入,更高空间、时间分辨率的遥感数据和长时间序列的气象观测数据将是植被-气候关系研究的重要数据来源.
Research in relations between vegetation and climate is a complicated system.The research in relations between vegetation and climate has become one important field of study on global change.It includes two aspects:first,research in responses of vegetation change to climatic change,and second,feedback research of changes in vegetation to climate change.This paper summarized an overview of relation researches between vegetation and climate based on remote sensing.Vegetation changes have showed obvious responses to climatic change at different scales,regions and time series,over the past few decades.Changes in vegetation growth are closely related to temperature and precipitation.Vegetation change at large scale resulted to local and regional climatic changes.Currently,there are various remote sensing data sets came from different data sources for the research on relations between vegetation and climate.Because single data source is limited in time,the integration application of multi-source remote sensing data is an important way to study relations between vegetation and climate for long time series.As the development of remote sensing,remote sensing datasets with bigger spatial and time resolution and long-time sequence climatic dataset will be important data sources for research in relations between vegetation and climate.
