摘要：

With application of the principle of economics, we study the theory of consumer surplus by eco- environment improvement. According to the types and trait of ecological effect in Heishan Gorge Ecological Improvement Area, integrating with research results in China and overseas, we bring forward the calculation method for ecological effect evaluation. On the basis of field survey, we set up the correlation parameters of effect evaluation, study the direct and indirect effect of all eco- environment improvement items, and calculate the total value of ecological effect.
