遥感技术监测水体叶绿素a含量的研究进展
|
摘要
随着环境水体污染和富营养化问题日显突兀,有效开展水体的水质监测是水体污染综合治理的基础,因此必须加强对水体水质的监测,其中叶绿素a是水体污染和富营养化程度高低的重要标志。遥感监测方法高效、快速地探测水体的污染物迁移,实现了水体的大范围实时监测,因此遥感技术的应用及研究对完善和提高水体水质监测能力具有十分重要的研究意义。针对遥感技术监测水体叶绿素a(Chl-a)含量的相关课题,从选题背景、研究意义、水质遥感技术监测Chl-a含量的原理、监测方法、所面临的问题等方面,阐述了遥感技术在监测水体Chl-a含量的研究进展,提出了目前所面临的问题,并进一步对遥感技术监测水体Chl-a含量的研究进展进行了展望。
With the increasing environmental pollution, water pollution and eutrophication problems are become more and more obvious, so it is necessary to strengthen water monitoring and water pollution control. Effective water quality monitoring is the basis of eutrophied water treatment. Chlorophyll-a is an important indicator of the level of water pollution and eutrophication. Remote sensing monitor can inspect pollutants migration, and a wide range of real-time monitoring of water can be achieved by remote sening. The application and research of remote sensing technology are of a great significance to the water quality monitoring. In this paper, we investigate the background, the principle and progress of remote sening monitoring technology. Meanwhile, the research progress of remote sensing technology is expounded, and the problems are put forward,and the developments of monitoring the content of Chl-a in water by remote sensing technology are discussed.
