摘要：Based on the analysis of river ecosystem
characteristics, the external problem of hydropower development is detailedly analyzed. Dam plays the
important role in regulating regional water resources, reducing the storage of
flood disaster, producing clean energy. However, the river system of
morphology, topography, water quality and
ecological environment are adversely affected. The controlling countermeasures
of ecological compensation mechanism, the artificial cultivation of ecological
system are proposed.
