None Of The Surrounding Mountain Forest Ecological Value Assessment And Construction Of Countermeasures

Forest ecology construct is more and more concerned by academia and decision-maker, has been a keystone and a marginal study field across forestry, ecology and economy etc. Forest ecology value quantification is leading trend of forest ecology construct.This thesis, combining theory study and demonstration analysis, illustrate the studying theory and means of Forest ecology environment value first, laying foundation of demonstration analysis. Second, make up the index system and size-up measure and size up the Forest ecology environment value of periphery mountainous land of Guanzhong further by the way of combined quantity and quality. The result show that the ratio of economy\ ecology and social benefit of periphery mountainous land of Guanzhong is 1.20 : 22.56: l,the general economy benefit ratio of guanzhong north and qinling north slope is 3.32 : 1. Third, put up with the trend of Forest ecology environment construct, size up the potential value of forestation in the near future. The ratio of the potential value and investment of forestation is 5.83 . 1, showing clearly that forestry construct has great benefit.At last, the policy and measure of planning, fund source, technology sustain and manage is put forward to improve and upgrade the forest ecology environment of periphery mountainous land of Guanzhong .
