Analysis of Ecological Base Flow of Baoerdesu River Based on Tennant Method
With the development of social economy and the increasing shortage of water resources,the contradiction between the protection of river life and health and river water use has become increasingly prominent.In order to ensure the continuous flow of the Baoerdesu River and realize the optimal allocation of water resources in the basin,based on the general situation of the Baoerdesu River and the current situation of water resources development and utilization in the basin and the existing problems of ecological base flow,the basic ecological flow and safeguard measures of the assessment section and management section of the Baoerdesu River were discussed by using the Tennant method on the basis of analyzing the assessment scope,control section and protection target of ecological base flow.It is proposed that the ecological base flow of the Baoerde channel head is 0.09 m3/s in the dry season and 0.4 m3/s in the wet season,which can provide reference for the determination of ecological base flow of similar rivers.
