高光谱遥感技术在国家环保领域中的应用

高光谱遥感技术在环境保护领域中应用广泛，本文概述了高光谱遥感技术在我国大气环境中污染气体、温室气体监测，水环境中重点水污染源水华、水质、饮用水源地安全监测，生态环境的生物多样性、植被类型监测、土壤污染等方面的应用情况，并指出目前存在国内高光谱卫星缺乏、数据处理和信息提取能力不足等问题，以及目前迫切需要发展搭载大气痕量气体差分吸收光谱仪、温室气体监测仪、高光谱成像仪等高光谱传感器的环境卫星后续星、加强高光谱数据处理和信息提取攻关研究、加快高光谱环境地面应用系统的建设等建议。

Application of Hyper-Spectral Remote Sensing Technology in Environmental Protection

Hyper-spectral remote sensing (RS) technology has been widely used in environmental protection. The present work introduces its recent application in the RS monitoring of pollution gas, green-house gas, algal bloom, water quality of catch water environment, safety of drinking water sources, biodiversity, vegetation classification, soil pollution, and so on. Finally, issues such as scarce hyper-spectral satellites, the limits of data processing and information extract are related. Some proposals are also presented, including developing subsequent satellites of HJ-1 satellite with differential optical absorption spectroscopy, greenhouse gas spectroscopy and hyper-spectral imager, strengthening the study of hyper-spectral data processing and information extraction, and promoting the construction of environmental application system.
