高光谱遥感在反演植被生理参数的应用综述

Summary on the Application of Hyperspectral Remote Sensing to Inversion of Vegetation Physiological Parameters

高光谱分辨率遥感技术是近20年来人类在对地观测方面取得的重大技术突破之一,也是当前及未来几十年内的遥感前沿技术。由于其具有光谱分辨率高、数据丰富等独特性能,因而在环境保护、地质找矿、植物生长监测等许多方面有着广泛应用。高光谱分辨率遥感在植被生理参数监测中主要有以下几方面应用:植物中氮素含量;叶绿素含量;水含量。

Hyperspectral remote sensing technology, being one of the most important breakthroughs acquired in the field of earth observation by human in the recent 20 years, is an advancing technology of remote sensing in the next decades. It has the special qualities of high spectral resolution ,plentiful data etc., so it can be extensively applied in environment protection, depo sit exploration, vegetation monitoring and so on. The application of hyperspectral remote sensing in monitoring physiological parameters of vegetation mainly has the following aspects：nitrogen content in plants, chlorophyll content, ;water content.
