Ecological Restoration Landscape Design Of Qinwangchuan Wetland Park

With the increasing emphasis on ecology and sustainable development in the field of landscape design,environmental protection and ecological restoration have become basic elements of landscape design.Qinwangchuan Wetland Park is a rare inland salt marsh wetland in China.The Lanzhou New Area where it is located has a high degree of soil salinization,damage to biological diversity,low wetland landscape benefits,scarce tourism resources,and poor tourism business It is necessary to carry out landscape design through artificial ecological restoration measures.Aiming at the current environmental problems of the eastern part of Qinwangchuan Wetland Park Phase I,this paper analyzes and designs landscape design from the perspective of wetland ecological restoration and sustainable development of wetland park landscape design.It follows the design concept of urban green heart,and the principle of giving priority to ecological restoration.The design ideas of the protection zone and the protection zone are proposed,and ecological restoration measures such as soil restoration,basement restoration,water system restoration,and plant restoration are proposed,and the wetland drainage system is improved by replacing the alkali soil with guest soil;the basement is dredged,and artificial floating islands and ecological revetments are designed to increase Wetland ecological level;rain and sewage diversion,setting up a sewage treatment plant,intercepting pollution from the source,purifying the wetland water body,and planting salt-tolerant and salt-reducing plants and other specific measures to achieve the ecological restoration of the Qinwangchuan Wetland Park landscape.The landscape design plan of Qinwangchuan Wetland Park Phase I is based on ecological restoration.The functional zone design is wetland experience area,landscape tourist area,wetland service area,science popularization area,and ecological conservation area.There is no car in the traffic planning and design park.The main park The road is a healthy walk around the lake,and the secondary park road is the main axis of the landscape.It connects the east and west areas of Qinwangchuan Wetland Park Phase I.At the same time,a scenic boardwalk is designed to bring tourists a hydrophilic experience while visiting the wetland landscape;Qinwangchuan The plant configuration and design of the eastern part of the first phase of the wetland park should reflect the functions of seasonal changes,wetland landscaping,wind and sand fixation,and ecological restoration of water system soil.Limited use of native tree species,plants suitable for saline-alkali land planting,and plants resistant to salt and water.Through the mix of arbor and grass and the layered mix of evergreen and deciduous plants,arbor and ground cover are combined to make the landscape,which extends the wetland landscape viewing time,improves the wetland plant level,and enhances the overall wetland landscape value.Planting large trees that are resistantto drought and alkali and wind and sand fixation as shelter forests and street trees to achieve wind and sand fixation and isolate urban noise and pollution;by planting aquatic plants that can absorb chemical elements in water on ecological banks,improve water eutrophication and purify water quality,Reduce salinity;arbor shrubs that are tolerant to salt and salt can be planted in the garden to reduce the salt content of the soil while creating ornamental landscapes.The ecological restoration landscape design of Qinwangchuan Wetland Park promotes the protection and development of Qinwangchuan salt marsh wetland,restores the wetland biodiversity,promotes the urban greening of Lanzhou New District,raises public awareness of environmental protection,and provides the public with a good place for leisure tourism.Let Qinwangchuan Wetland Park be a green space shared by the people.
