摘　　要：河流生态流量是维系江河生态系统的基本要素,是控制水资源开发利用强度的重要指标,开展生态流量研究是为河流健康代言的一项重要工作。根据云南高开发利用河流特点,以金沙江流域牛栏江水系为代表开展生态流量研究,按照河流“用水期”“防洪期”和“蓄水期”的划分提出Tennant改进法,并与3种常用的水文学方法进行对比分析。通过比较,本研究提出的Tennant改进法在满足开发利用河流用水特性、天然河流年内丰枯变化规律、河道内生态环境状况、枯水期生态流量满足率方面有明显优势。The ecological flow of rivers is the basic element for maintaining a river ecosystem and an important indicator for controlling the intensity of water resource development and utilization.Studying ecological flow is a significant part of endorsing river health.According to the characteristics of the intensively developed and utilized rivers in Yunnan Province,this paper takes the Niulan River system in the Jinsha River Basin as a representative to carry out ecological flow research.It proposes an improved Tennant method according to the division of the river s“water use period”,“flood control period”,and“water storage period”and compares it with three common hydrological methods.According to the comparison,the proposed improved Tennant method has obvious advantages in meeting the water use characteristics of rivers in development and utilization,the variation law of natural rivers abundance and dryness throughout the year,the ecological environment conditions in the river course,and the ecological flow satisfaction rate in dry seasons.
