Discussion on Landscape Ecological Reconstruction Model of Urban Wetland Park Hydro-fluctuation Zone——Taking Nanchang Malanwei Wetland Park as An Example
Due to seasonal inundation and exposure,repeated erosion of water flow and frequent hu-man activities,hydro-fluctuation zone is an ecologically sensitive and vulnerable area of urban eco-system.Previous studies mostly focused on soil,vegetation,habitat and pollutants in the hydro-fluctuation zone of the Three Gorges Reservoir area or large rivers,but paid little attention to the hydro-fluctuation of urban wetland park,especially its ecological reconstruction and ecological resto-ration.Therefore,taking Maranwei wetland Park of Nanchang city as an example in the paper,the current situation and existing problems of the hydro-fluctuation zone is systematically analyzed,and based on this,the principles and models of ecological reconstruction of the hydro-fluctuation zone of wetland park are put forward,in order to restore the ecological,environmental and economic func-tions of this area to the maximum extent,so as to provide a reference for the ecological restoration and reconstruction of the hydro-fluctuation zone of other urban wetland parks.
