The Study On Construction Pattern And Comprehensive Benefit Of The City Protective Forest Project In Xilinhot

The ecological environment is foundation of humanity's survival and development, that is foundation of the social progress and the economic development. The ecological environment protection,the ecological environment construction and sustainable development are one of world attention major issues. This project's goal is promoting Xilinhot's economy and the sustainable development, that improved the Xilinhot's ecological environment and established an ecology green screen.The research indicated: In The Xilinhot city , the different tree species preservation rate and growth condition of urben protective forest are difference; The different forest belt has different level for reducing wind speed , the bush mainly reduces the surface wind speed, the tree reduces the high-level wind speed; Compares with the CK, the type of plant and biomass are increasing in urban protective forest ; The urban protective forest improves soil fertility very obviousiy. Compares with the CK, Nitrogen,Phosphorus and Potassium have large enhances; The urban protective forest project also has obvious economic efficiency, the environmental condition's improvement causes the grass's output enhance year by year. In addition, tree of the urban protective forest produces branches and leaves, which cause the direct economic efficiency, the benefit is very considerable.At the same time, the urban protective forest also has the obvious social efficiency, through project implementation, not only led the Xilinhot development, but also solves employment. The project improved people's working condition and the living conditions, which promotes local economic boom and the social stability.
