摘要： 植物体内部生理生态过程对物质和能量的交换与传递起着重要作用,而植物体本身的生化物质含量影响和控制着这些过程的进行。随着成像光谱技术的发展,利用高光谱遥感数据估测植被生化信息成为遥感发展的前沿。论文以云南勐遮地区高光谱星地同步试验为例,详细介绍了试验中研究区与最佳观测时期选择、研究样点选择、试验内容、方法以及试验流程设计等,并着重比较星地同步试验与传统野外试验的区别,旨在为今后该类试验的设计与实施提供经验借鉴。结果表明,星地同步试验在设计和实施时必须充分考虑传感器本身的性能特点、观测数据获取时的潜在风险、遥感影像处理的需要以及卫星观测数据、地面光谱数据和生化数据等的同步性问题。

Abstract: Physiological and ecological processes within plants play an important role of the exchange of materials and energy.The contents of biochemical substances influence or even control the progress of those processes directly or indirectly.To estimate biochemical information of vegetation becomes a new branch of remote sensing research and application with the development of imaging spectrometry.This paper presents detailed introductions and analyses on Mengzhe(Yunnan) hyperspectral satellite-ground synchronous experiment carried out in the end of March,2005,to give instructions on the selection of research area,observation date,experiment methods,and the design of experiment processes.The difference of satellite-ground synchronous experiment and ordinary field experiment is emphatically analyzed so as to provide helpful experience for the design and implement of similar synchronous experiments in the future.Results show that(1)sensor performance,(2)potential risk on earth observation data,(3)requirements for remotely sensed image processing,and(4)the synchronous issue of satellite observation data,ground measured spectral data and biochemical data,need more attention in the design and implement of satellite-ground synchronous experiment rather than ordinary field experiment.

Key words: remote sensing, satellite-ground synchronous experiment, hyperspectra, biochemical information
