水色及其与藻类的关系

Relationship between watercolor and phytoplankton

水色是水环境质量评价中一个重要的综合性指标,不同的水色反映水质的营养状况;藻类群落是水体营养状况的生物表征,对水色具有重要影响作用。本文通过分析不同水色中的藻类优势种群及其作用,认为藻类优势种群是决定水色的主要生物因子;阐明了藻类与水色之间的相互关系以及施肥改变水色的内在机理,水体营养状况决定了水体藻类群落结构进而决定不同的水色;并结合实践对如何判断不同藻类种群引起的不同水色提出了看法,同时对改变和调控水色的方法和途径进行了论述,为相关生产和水环境管理提供理论依据和技术指导。

Watercolor is an important index for aquatic environmental assessment. Watercolor was affected remarkably by phytoplankton community. The effects of predominant algal species on watercolor and relationship between algae and watercolor were reviewed. The mechanism of fertilization affecting watercolor was also analyzed and regulating methods on watercolor were advised. Method on how to distinguish the predominant algae from different watercolor was put forward in this paper to instruct the water management and relative aquatic industry.
