摘要： 以水量丰富但水体污染程度普遍较高的平原河网地区为研究区域，分析平原河网地区环境流量的概念和内涵；探讨不同功能目标下环境流量的计算要素和特征；基于动态权重法提出平原河网地区环境流量的等级设定和评价标准，并利用松浦大桥周围的水文水质数据，对上海环境流量状态进行了初步评价.本研究为实现以河流多元功能为目标的丰水地区环境流量计算和评价提供了一种思路.

Abstract: This paper analyzed the characteristics of environmental flow in plain river network areas. By using dynamic weight，a calculation method under different water quality and quantity combinations was designed. The environmental flow data of Songpu Bridge on Huangpu River were used to assess the environmental flow situation in Shanghai area. This research might provide a new way to understand, describe and calculate environmental flow guided by multifunction of river management.

Key words: environmental flow, dynamic weight, calculation and assessment, river network plain, environmental flow, dynamic weight, calculation and assessment
