摘要
应用遥感技术进行水质监测较常规监测具有巨大优势,能快速、大尺度、低成本的监测水质参数在时空上的变化状况。本文首先简要阐述了内陆水体环境遥感监测的基本原理;其次,介绍了常用水质参数的遥感监测研究现状,包括叶绿素a(Chl-a)、悬浮物(SS)、有色可溶性有机物(CDOM)以及总磷(TN)、总氮(TP)等其他水质参数,并将其划分为经验模型和生物光学模型两种监测方法;再次,对常用的遥感数据源进行了介绍和优缺点的评述;最后,讨论了内陆水体环境遥感监测误差来源,并对今后内陆水体环境遥感监测研究重点进行了展望。
Using the technique of remote sensing to monitor the water quality is an advanced tool compared to traditional monitoring methods.This paper reviews the progress of application of re-mote sensing in inland water environment monitoring.Firstly,the principles of water environment parameters retrieval were addressed.Secondly,the applications of several inland water quality pa-rameters in monitoring by remote sensing were discussed,including Chlorophyll a（Chl-a）,Sus-pended Solids（SS）,Colored Dissolved Organic Matter（CDOM）,Total Phosphorus（TP）,Total Ni-trogen concentrations,transparency and turbidity of inland water and so on.And then we classi-fied the existing retrieval models into empirical model and bio-optical model.Thirdly,different remote sensing images and their advantages and disadvantages for inner water environment moni-toring were introduced.Finally,we discussed the problems of retrieval precision and proposed some suggestions for further research.
