| Abstract: | From the viewpoint of the relationship between the ecosystem and forest, this article expounds that the closed forest can form multi layer mixed forest, which conform to the plant community positive succession in order to make full use of the light energy to increase biomass, make full use of water and nutritions substances in the soil to increase incrment, and obtains the ecological functions, environmental effects and economic benefits of the multi resource colony. |
