Measurement assessment of forest benefit in reducing flood disaster

Abstract

Based on the analysis of forest inner mechanism, forest benefit in reducing flood disaster is defined. Through the characteristic analysis of forest benefit in reducing flood disaster, it is suggested that it is impossible to adopt the microanalysis method for studying the forest benefit in reducing flood, the macro analysis is the only method to be adopted. With the special case of disaster flooding of Changjiang River happened in 1998, the forest benefit in reducing flood disaster was scientifically assessed. The estimated results of forest benefit in reducting flood shows that forest vegetation establishment is the radical, way to control flood, but it only equals to 5 percent of the total benefits of water conservancy facilities.
