摘要
本文简述了遥感技术在水质监测中的意义,总结了可用于遥感监测的水质指标,同时对清澈水体、一类水体、二类水体及污染水体的光谱特征分别给予了介绍。着重讨论了水质遥感的基本方法,并在此基础上从营养盐、有机污染物和营养状态指数三项水质指标出发,对其研究现状进行了阐述,最后进一步提出了水质遥感领域中存在的主要问题,并展望了其未来的发展方向。
As a new method of water quality, more importance has been attach to remote sensing technique, which has been applied in measuring and retrieving of water quality parameters. This article generalized the significance of remote sensing technique in water quality, summarized water quality index which is available for remote sensing monitoring, introduced the spectrum feature of clear water, Case- I water, Case-II water and polluted water, emphatically discussed the base method in remote sensing of water quality as well as the research and development on nutrients, organic pollutants, trophic state index. Finally, the article pointed out the princi- pal problems and looked into the feature trend of remote sensing of water quality.
