摘要:
在生态调查基础上从微生物学、理化及叶绿素a指标等对南水北调中线水源区进行了生态监测.结果表明,水源区为寡污型水体,水体基本处于贫-中营养状态,水源区指标除TN为Ⅲ类水质外,其它监测指标均符合Ⅰ类水质标准.是理想的水源地.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:
Based on the ecological survey, the ecological indexes of microorganisms, physico-chemicals and chlorophyll-a was measured on the water source area of the middle-line project of Transferring Water from South to North, 2005. The result showed that the nutrition type of the water source could be regarded as mesotrophyic;Danjiangkou Reservior is suitable for water source because the indexes except TN belong to the standards of Grade I water. This study would provide scientific information for data bank of long-term ecological research on middle-line project and policy of ecological environmental protection
Key words:  The water source area of the middle-line project of Transferring Water from South to North  microorgan-isms  ecological monitoring  trophic state index  water quality
