Abstract:

The unbalanced mechanisms of ecological water environment of the wetland in Daxinganling forest region are influenced by the enhancement of greenhouse effects and the result of Globle warming,the deforestation of virgin forest and the afforestation on the drainage wetland.The interactional factors will accelerate the surface runoff,enlarge the melting depth of the frozen stagnant water and the melting amount,and increase the surface evaporation.It is the human activities that increase the output of the surface water and the ground runoff from the wetland and its basin to the mountainous valleys and result in the unbalance of ecological water environment in the wetlands.Therefore,the distribution of the virgin forest,the layer of the frozen stagnant water and the wetland in Daxinganling are shrinking to the northern part and the higher elevation.The ecological water environments of forest in Daxinganling are degraded further.
