高光谱遥感在生态系统研究中的应用进展

Applications of Hyperspectral Remote Sensing in Ecosystem:A Review

遥感技术在生态系统调查与研究中具有广阔的应用潜力,但是传统的多光谱遥感主要侧重在面上的普查,很难对生态系统中各种复杂地物属性和生化参量进行精确反演。高光谱遥感突破了光谱分辨率的限制,大大提高了人们获取多种生态系统模型输入参数的类型和精度。在阐述高光谱遥感的原理和信息特点的基础上,系统评述了目前国内外高光谱遥感在生态系统过程与属性研究中的应用,并对未来高光谱遥感在生态学领域的研究方向做出展望。

Remote sensing has profound implication in ecosystem investigation and research. However,traditional multispectral remote sensing data usually focused on the mass screening. It was difficult to be used to inverse the complicated properties and biochemical parameters of ecosystem for the limitation of spectral resolution. Hyperspectral remote sensing, which measure large numbers of narrow spectral bands, could greatly improve the accuracy and types of input parameters of ecosystem models. In present study,we systemically reviewed the implication of hyperspectral remote sensing in ecosystem processes and properties based on expounding the principle and characteristics of hyperspectral remote sensing,and proposed the potential implication of hyperspectral remote sensing in ecology.
