摘要:
通过对南水北调中线水源区水体浮游植物的调查,结合理化指标的逐月测定,结果表明:该水域共有浮游植物8门40属71种(包括变种),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.

Abstract:
According to the investigations in water source area of the middle line project of transferring water from south to north in March, May, September and November 2004, 71 species and its variant of phytoplankton were identified, which belong to 8 phylum and 40 genera. The dominant species were Baciilariophyta. The species and the numbers of phytoplankton iu different seasons and water areas showed marked variation. The water pollution could be indicated by phytoplankton. The nutrition type of water source area could be regarded as mesotrophy. This study would provide scientific base for the data bank of long-term ecological research and the policy of ecological environmental protection on the middle line project.
Key words:  Water source area of the middle line project of transferring water from south to north  biological monitoring  water quality assessment
