Research On Surrounding Environmental Impact Analysis Of Qunli Wetland Park And Relevant Optimizing Strategies

Recently, affected by planning concept and design method of the low impact development(LID)in America, the sustainable drainage system(SUDS)in Britain, the water sensitive urban design(WSUD)in Australia and the Sponge City in China, the development and construction of urban wetland parks has become increasingly popular in both Chinese and western countries. The urban wetland park can protect and restore wetlands, prevent waterlogging, supplement groundwater, Purify sewage and purify air. It is an important landscape infrastructure park on the urban sustainable storm-water management and has a negligible impact on improving the environment and dealing with the urban climate change. In order to deal with the complexity of the urban environmental problems, many scholars advocate to pay attention to the construction and design of urban wetland park and advocate to construct more urban wetland parks. However, many researchers ignores the influences of surrounding urban environment in the construction of urban wetland parks, which causes many developed wetland parks became less sustainable and were aggravated in the accelerating urbanization in China. The Qunli wetland park(Harbin, Heilongjiang province) is the first rain-flood park in China and is widely seen as a success in urban wetland park development, which plays a significant role in improving flood control in this area. The paper researchs the built environment of Qunli Wetland Park and its influence,Analysis the actual impact on urban rain flood and the surrounding environment after the completion of the park, find the problem of the park under the fast urbanization and then puts forward the corresponding strategies. and provide a reference for sustainable remediation and optimization of Urban Wetland Park.This paper takes the relevant researches implemented in western countries as references. It begins with analysis of the background, meaning, methodology of the research to understand the gaps in researches about wetland park construction in China and discusses the importance of the influence examination of urban wetland parks on surrounding areas. Then relevant basic theories are reviewed in this research to provide theoretical references for this research. Moreover, a series of methods including observing, questionnaire, environmental monitoring and field investigation are applied in this research to understand the impact of Qunli Wetland Park to surrounding areas in terms of spatial environment, ecological environment and social economy and discuss the problems emerged in the construction and operation of Qunli Wetland Park. Finally, this research provides a series of strategies in terms of macroscopical urban spatial aspect, mid-view surrounding environment and microcosmic inner environment to optimize the sustainability of Qunli Wetland Park.Different from focusing on the planning and design of Urban Wetland Park, the paper plays attention to researching the built environment impact on the surrounding environment. Based on the actual effect data of Qunli wetland park, we discuss the practical benefits of Wetland Park, and then put forward the optimization strategy. The environment optimization strategies of Urban wetland park should not only include the optimization of wetland ecological system itself,but also include the protection of Wetland Park from the macroscopic view of city and the guidance and control from the surrounding environment. Considered the park located, the interaction of regional economy, cultural customs and environmental resources, Urban Wetland Parks not only achieve the optimization park itself, but also optimize the surrounding environment, to realize the sustainable development of Urban Wetland Park.
