摘要
通过对南水北调中线水源区水体浮游植物的调查,以及对理化指标的测定,结果表明:该水域共有浮游植物7门40属66种3变种2变型,其中以硅藻门的种类占优势,浮游植物的种类和数量随季节和水域不同而呈现差异,浮游植物对水体污染具有较好的指示作用,水体为寡污型水体.本研究为建立中线水源区长期生态研究数据信息库及库区生态环境保护政策制定提供科学依据.
According to the investigations in water source area of the middle line project of transferring water from south to north 71 species and variant of phytoplankton were identified, which belong to 7 divisions and 40 genera. The dominant species were Bacillariophyta. The species and the numbers of phytoplankton in different seasons and water areas showed marked variation. The water pollution can be indicated by phytoplankton. The nutrition type of water source area could be regarded as mesotrophy. This study will provide scientific base for the data pool of long-term ecological research and the policy of ecological environmental protection on the middle line project.
