成像光谱遥感在森林病虫害监测中的应用研究

摘要

森林病虫害是"林业三害"之一,对森林健康造成了极大的威胁.成像光谱遥感是森林病虫害监测的有效技术,为森林病虫害的防治提供了依据.介绍了成像光谱遥感监测森林病虫害的主要原理,根据不同空间尺度下的成像光谱仪搭载平台,阐述了成像光谱遥感监测森林病虫害的研究现状,从提取植被生化参数、提取光谱特征参数、建模反演三个方面论述了成像光谱应用于森林病虫害监测中的主要方法,并展望了成像光谱遥感在森林病虫害监测中的发展趋势.%Forest pest and d isease causes overwhelming threat to forest health. Imaging spectral remote sensing can monitor the condition of forest pest and disease effectively, and provide important gist for prevention and control of them. The main theories about monitoring forest pest and disease using imaging spectral remote sensing were introduced in the review. The research status was elaborated based on different imaging spectrometer. The main methods were discussed from extracting bio-chemical parameters and spectral feature parameters and modeling inversion. At last, the following tendency of imaging spectral remote sensing was forecasted in the identification and monitoring of forest pest and disease.
