清河干流生态基流计算分析
Calculation and analysis about ecological baseflow in main stream of Qinghe river
摘要
Abstract
Based on the runoff data in Bakeshu station and Kaiyuan station from 1988 to 2009 ,the paper chose five hydrological methods including Tennant method , average flow method in the driest month with 90%frequency , NGPRP method to calculate the ecological baseflow of Qinghe river .According to the comparasiom and analysis of calculation result ,it discovered that Tennant method is the most sutible for baseflow calculation in main stream of Qinghe river .Based on the result of Tennant mthod ,the paper com-pared which with actual runoff .As the descrease of annual rainfall , it is more difficult to maintain the ec-ological baseflow in Qinghe river .关键词
