Wetlands in Fenhe River watershed are composed of various kinds of wetland

including wetland in inland estuary

river wetland

lake wetland

reservoir wetland

swamp wetland

and meadow wetlands.The total area of the wetlands is 930.51 km2.The eco-environmental characteristics of the wetlands are of broad distribution

various types

and abundant biodiversity.They are severely degraded because of human activities and other natural causes.Polluted water from mining coal

chemical engineering

and metallurgical enterprises results in the faster deterioration of wetland eco-environment.Unsuitable exploration of flooding plain and lakes causes the gradually decreased wetland area and seriously damaged vegetation of wetland.Over-reclamation of the wetlands destroys the habitat for waterfowl and over-prey and illegal hunting lead to greatly decreased biodiversity.Over-exploration of underground water and coal mining accelerate the deterioration of wetland eco-environmental functions.
