Accounting on Minimum Ecological Water Demand in Lower River of Hydraulic Engineering in Mountain Area -A Case Study on Changfang No. 2 Reservoir Hydropower Station, Shennongjia Forest Region, Hubei Province, Central China

摘要

On the premise of protecting the river hydrobiology's habitat, we investigated the problem of river's ecological water demand in mountain area. This paper is the establishing of preliminary research on the counting of minimum ecological water demand. And the paper also takes Changfang No. 2 reservoir hydropower station project in Shennongjia Forest Region, Hubei Province, central China for instance, put forward the result of minimum ecological water demand in the lower river of the dam, which offers reasons for the environmental impact assessment and scientific operation of the reservoir hydropower station project.
