| Abstract: | It's important to protect the biodiversity in Labagoumen forest region since the ecological function of the biodiversity of the forestry system has aclose relation to Beijing citizen's life.The value of forest biodiversity was calculated which incuded direct use value and indirect one of 8.4567 million Yan and 249.18 million Yan respectively in Labagoumen forest region,the result indicated that the economic function value was by far larger than the material value which all produced by the biodiversity.The forest vegetation system may absorb 0.38 million Ton of CO 2 and release 0.284 million Ton of O 2 yearly.Also,it could decrease the erosion of soil by 0.484 million Ton and absorb 1634.5 Ton of SO 2 every year. |
