Hydro Development-Induced Environmental Impact on River Ecosystem

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.
