Hydropower, reservoir and mineral industries have been increasing concerned for the difficulty of soil and water conservation and now become a focus of conservation. Soil and water conservation status in the development process of hydropower, reservoir and mineral industries was investigated extensively, in some provinces of well-done conservation as Zhejiang, Shaanxi and Shanxi，special investigation was carried out on some enterprises in which some typical enterprises were profoundly looked into under the support of these projects. After clearly contrasting the existed problems and lessons, we think that it is practicable and necessary to extract some funds from the benefit of hydropower, reservoir and mineral development as a part of the conservation financial resource. We propose that extracting certain proportional funds from benefits of these industries should be legislated and put the fund listed before taxing.
