摘　　要：对区域生物多样性进行快速、有规律的监测与评价,在生物多样性研究和生物保护中有重要意义。近年来,遥感技术被广泛用于生物多样性研究,能提供区域-大陆乃至全球尺度的生物多样性信息,且费用相对低廉,数据一致性好,并能得到有规律的更新。本文介绍了遥感用于生物多样性研究的原理和优势,总结了生物多样性遥感在实践中的主要应用途径,包括景观格局指数、NDVI、光谱变异假说(SVH)和高光谱遥感等方面。本文着重介绍了SVH以及波段选取问题的研究进展,分析了这些应用途径的优缺点,总结了生物多样性遥感在实际应用中的不足,并对该领域的模型、传感器和尺度效应等方面的未来发展方向进行了展望。Quickly and regularly monitoring and assessing regional biodiversity is of great signifi- cance for biodiversity research and conservation. In recent years, remote sensing technology is extensively applied in biodiversity research, and can provide regional, continental, and global biodiversity information. This approach is low cost and high data consistency, and updated regu- larly. This paper introduced the principles and advantages of remote sensing in biodiversity re- search, and summarized the main application aspects of biodiversity remote sensing in practice, including landscape indices, NDVI, spectral variation hypothesis （SVH）, and hyperspectral re- mote sensing, with the focus on the analysis of the advantages and disadvantages of these applica- tion aspects and the recent research advances in SVH research and optimal band selection. The deficiencies in the remote sensing biodiversity research were pointed out, and the development trend in this research field, such as models, remote sensors, and scale effect, were prospected.
