| 摘 要： | 有色可溶性有机物(CDOM)是水体中一类重要的光吸收物质,在短波的吸收大大降低了紫外辐射在水体的衰减,因而其光学行为和生物地球化学循环将对水体生态系统产生重要影响。CDOM在水体生态系统、水色遥感和全球碳循环研究中具有广阔的应用前景。文章综述了国内外CDOM研究现状与动态,其中包括CDOM的光吸收特性、荧光特性、光化学降解以及CDOM和DOC浓度的水色遥感,最后提出在内陆水体湖泊中开展CDOM研究的设想。

| Abstract: | Chromophoric dissolved organic matter(CDOM) is one of the major light absorbing constituents in natural waters,whose optical behavior and biogeochemical cycle play an important role in aquatic ecosystems CDOM light absorption is highest in the ultraviolet(UV) region of the spectrum.CDOM has a broad application prospect in aquatic ecosystems,optical remote sensing and carbon circulation in the sea.This paper demonstrates the advances of CDOM in aquatic ecosystems,including optical absorption properties,fluorescence,CDOM photochemical degradation and color remote sensing of CDOM and dissolved organic carbon.The paper also present some study assumptions in inland waters especially in lake Taihu. |

| Keywords: | chromophoric dissolved organic matter exponential spectral slope fluorescence photochemical process color remote sensing |
