托什干河生态基流与基本生态环境需水量计算研究

Study on Calculation of Ecological Base Flow and Basic Ecological Environmental Water Requirement in Toshigan River

文章通过分析托什干河水资源开发利用情况和生态现状,充分考虑河流生态功能,调查研究并通过改进Tennant法、年型划分法、最枯月平均流量多年平均法、Qp法等四种方法计算出沙里桂兰克断面的生态基流和基本生态环境需水量,并确定了其他断面的生态基流和年基本生态环境需水量,为托什干河生态流量管理与调度提供参考依据。

In this paper,based on the analysis of the development and utilization of water resources and ecological status of The Toshigan River,the ecological function of the river is fully considered,and the ecological basic flow and ecological environmental water demand of the Shaliguilanke section are calculated by four methods,including improved Tennant method,annual classification method,annual average method of the driest monthly flow and Qp method.The ecological base flow and annual basic ecological environmental water demand of other sections are determined to provided reference for ecological flow management and regulation of The Toshgan River.
