Research On Landscape Architecture Of Urban Wetland Park Based On Development Potential Evaluation

Urban wetlands, as part of urban ecosystem, have a unique function. With advances in construction of ecological civilization, urban wetland parks are in greater demand. However, during their construction, problems have arisen. The form of the park has won much more attention than its ontology characteristics; the overgeneralization of construction has influenced the function of a wetland park; the ecological system has been overdeveloped rather than being protected; and resources are wasted and not in full application effect. Those have gradually attracted people’s attention. There is aimlessness in the development and construction of an urban wetland park and its planning and design is too dependent on a certain designer’s experience and personal qualities. To deal with the above issues, the evaluation system of urban wetland park development potential is established in this paper with analytic hierarchy process, Delphi method and fuzzy grade method. Its feasibility in guiding the planning and design of an urban wetland park is also studied. Finally the conclusion is drawn in two aspects:Theoretical research:(1)The theoretical researches on the present development and construction situation of urban wetland parks, the wetland tourism and tourism evaluation index systems at home and abroad are reviewed in the paper. The evaluation system of urban wetland park development potential with total 24 indexes is established focusing on practicality and guidance in landscape planning and design. Its criterion layer contains social factor, ecological environment, behavior psychology and landscape image. (2) Through the practice of landscape planning and design of Boya Urban Wetland Park in Zunyi County, it is agreed that ecological environment is the foundation, landscape improvement the method, human-friendly factor the guarantee, and project planning the key.Practical research:(1)The system of Boya Urban Wetland Park in Zunyi County is evaluated by the evaluation system of Urban Wetland Park development potential. The result is 26.89 (the full score is 40). There are 13 matching factors, showing that the wetland is good in present situation and potential and valuable in development. Indexes with matching coefficient less than 0.8 are the emphasis in improvements. (2) Based on the evaluation results, Boya Urban Wetland Park’s landscape is planed and designed. The general orientation as the ecological leisure wetland is proposed; the layout of one ring, two belt, three zones and multiple points is adopted; and the overall design is conducted from three aspects-landscape image, ecological environment and behavior psychology. Meanwhile, the leisure wetland zone, the constructed wetland zone, and the farming wetland zone are separately designed.
