The Comparison of the Community Features between the Constructed Wetland and the Natural Wetland in Nansi Lake

Abstract:

Thirteen typical plant communities were investigated in Xinxuehe constructed wetland restored for five years and in Gaolou natural wetland restored naturally for eight years. Both wetlands are located in Nansi Lake area. The species composition, coverage, aboveground biomass and biodiversity indices were compared between the communities from the constructed wetland and the natural wetland. The results showed that the constructed wetland and the natural wetland had similar emergent species and typical species of their own, however neither coverage nor aboveground biomass showed significant differences. In the meanwhile, we found that the biodiversity of natural wetland is relatively higher than the constructed wetland. For the wetland restoration and the water quality quick improving, it is suitable to use artificial ways to promote the restoration of wetlands which converted from the farmland in Nansi Lake area; in the other hand, the natural wetland restoration is more valuable for the biodiversity conservation in the long run.
