摘　　要：本文以连续流动注射方法测定了2018年4—12月大连市5座大型供水水库的富营养化影响因子总磷、总氮以及高锰酸盐指数的浓度,根据《地表水资源质量评价技术规程》(SL 395-2007)的要求,对该5座大型水库的富营养化状态进行了评价,并对氮磷比以及季节变化与水库富营养化状态的关系进行了探究。该研究方法及结果以期为大连市水库富营养化的防控防治工作提供技术指导及理论支持。In this paper,the concentration of total phosphorus,total nitrogen and permanganate index of five large water supply reservoirs in Dalian from April to December,2018 was measured by continuous flow injection method. According to the requirements of Technical Specification for Quality Evaluation of Surface Water Resources( SL395-2007), the eutrophication status of the five large reservoirs was evaluated,and the relationship between nitrogen-phosphorus ratio and seasonal variation and the eutrophication status of the reservoirs was explored. The research methods and results are expected to provide technical guidance and theoretical support for the prevention and control of reservoir eutrophication in Dalian.
