遥感技术在森林树种多样性监测中的应用研究进展

Research Progress in the Application of Remote Sensing Technology to Forest Species Diversity Monitoring

树种多样性的快速、有效监测能够促进生物多样性保护与研究以及森林可持续管理。遥感技术正逐渐成为森林生物多样性大面积快速监测的新兴手段,为树种多样性空间格局信息的快速提取提供了有力保证。以数据源为线索,文中系统阐述了近年来多光谱遥感、高光谱遥感、激光雷达、微波遥感及多源遥感协同方法在树种多样性监测中的应用研究现状,并从数据源、数据平台、遥感异质性指数、数据时间特征和监测模型5个方面讨论了森林生物多样性遥感监测研究的发展趋势,旨在为生物多样性遥感监测研究提供有益启示。

Rapid and effective monitoring of tree species diversity can promote biodiversity conservation and research as well as sustainable forest management.Remote sensing technology has gradually become an emerging method for large-scale rapid monitoring of forest biodiversity,which provides a strong guarantee for the rapid extraction of information on the spatial pattern of tree species diversity.Taking the data source as a clue,this paper systematically reviews the research on the application of multi-spectral remote sensing,hyperspectral remote sensing,LiDAR,microwave remote sensing and multi-source remote sensing synergistic method to tree species diversity monitoring in recent years.The development trend of the research on remote sensing monitoring of forest biodiversity is discussed from the five aspects of data source,data platform,heterogeneity index,data temporal characteristics and monitoring model,aiming to provide enlightenment for remote sensing monitoring of biodiversity.
