| 摘要: |
| [目的]探讨更好地度量河流流量生态效益的单位、核算参照值和计算方法.[方法]针对河流径流量生态效益参照值选取困难,将河流流量生态效益理解为生态效用,借鉴Tennant描述的河流生态流量与柄息地质量关系的思想,给出河流径流生态积分概念、内涵和计算公式,用来衡量河流流量生态效用大小,用生态积分表示河流径流流量的生态效益.最后,以黄河龙羊峡和刘家峡水库2003年调度为例进行了方法检验.[结果] 2003年黄河龙羊峡和刘家峡梯级水库对花园口站非汛期的生态基流补偿效益为289.4亿生态积分,其中龙羊峡对花园口站生态基流补偿效益为197.5亿生态积分,刘家峡对花园口站生态基流补偿效益为91.9亿生态积分.[结论]河流径流生态积分度量对径流生态效益进行定量衡量,用生态分弥补了衡量河流生态基流效益的参照值缺失,可以对水库生态调度等进行合理评价. |

| Abstract: |
| 【Objective】 The research was to study the unit,reference value and caculation formder of ecological river flux.【Method】 The calculation formula of river flow total ecological mark was put forward for discussing on measuring the ecological benefit of river flow by using reference tennant method idea of describing the relation between the ecological flow and the habitat quality.Finally,taking Longyangxia and Liujiaxia Reservoirs on Yellow River as demonstration to test the method.【Result】 The result of the calculating case shows that the basic ecological flow compensation benefits were 28.94 billion ecological marks in 2003,which Huayuankou Station had obtained from Longyangxia and Liujiaxia reservoirs regulation.Namely,Longyangxia and Liujiaxia reservoirs respectively provided 19.75 billion ecological marks and 9.19 billion ecological marks of basic ecological flow compensation benefits for Huayuankou Station. 【Conclusion】 The article was for the purpose of the quota carrying on the weight to the runoff ecological benefit,laying the scientific foundation for the reservoir ecology dispatch. |
