Study On Planning And Design Of Urban Ecological Wetland Park

With the rapid development of urbanization in China,the urban population is increasing and the per-capita resources are gradually decreasing.Therefore,the protection of urban wetland resources is facing great challenges.In the construction of urban wetland parks in various areas,there are also some problems,such as over-exploitation and utilization,copying blindly,reducing ecological benefits and homogenizing with waters-cape parks,and so on.Thus,in order to study more systematically the methods of comprehensive conservation,scientific planning and construction of urban wetland resources,this paper respectively adopts the methods of basic demonstration,multi-disciplinary research,case analysis and field research as well as project practice,to carry out the research.In this paper,first of all,the research trends,concepts,types and related theories of urban wetland parks at home and abroad are discussed through data collection.Secondly,it will compare and analyze five examples of natural urban wetland parks and five examples of artificial urban wetland parks in detail.Through case analysis,the article will integrate the relevant design theory,technical methods and existing problems.Combining it with landscape ecology theory,elastic landscape design theory,ecological recreation theory and low impact development theory,this paper sums up the planning and design strategies and methods of urban wetland park,such as the strategies of landscape ecological design,low impact design,elastic landscape design and ecological recreation design;as well as the methods such as surface-flow and underflow synthetic wetlands,geothermal systems,ground temperature cooling systems,permeable roads and grass grooves,etc.Finally,the research results are applied to the practice of Longzi Lake planning and design project in Zhengdong New District,with the overall design conception.On the basis of wetland resources conservation,Longzi Lake Wetland Park is divided into dynamic and static zones,with the designed ecological service facilities,mainly combined local native plants,with the collection and purification system of city rain water,so as to build the urban wetland landscape mainly base on ecological protection,with leisure,science and education,experience,sightseeing as a wholeIn conclusion,through the research and practice of urban wetland park,this paper tries to provide scientific theoretical basis and practical experience for the planning and design in future.
