不同含量和类别的水质参数的水体光谱特征不同,这使得遥感影像能用于水体水质的监测。本文简要介绍了遥感监测水质的原理,监测的几类水质参数,常用的方法和几种典型水质参数的光谱特征及其遥感研究方法和目前研究的进展情况。最后讨论了这一领域目前仍然存在的一些问题。
The water with different kinds of quality parameter or different contents of the same parameter has the different spectral signatures, what makes possible to use the remote sensing data to monitor the water quality. This paper introduced those topi~ in brief: the principles of monitoring water quality using remote sensing techniques; the water quality parameters, which carr'btfmonl- tored; generally used methods and the spectral signaturds of typical water quality parameters; the development process and status of monitoring water quality using remote sensing. Finally, some key problems existed in this field were discussed.
