Exploration In The Construction Of Urban Wetland Research

Wetland is the earth surface interaction to form unique ecosystem, is one of nature’s rich biological diversity of ecological landscape. Urban wetland as "kidney of the earth", is a financial social, economic, natural integration in the complex ecosystems and complex resource system, the maintenance of biodiversity, regulating regional climate and material circulation, improve the urban water environment, rich urban ecological landscape, improve the taste of many functions of the city, it is an important way to build a harmonious society to create a "water city of ecological civilization" and "livable city".At present domestic and international research on urban wetland was restricted to a particular aspect of the function of a particular wetland or wetland planning and design, but urban wetland system constructed on a macroscopic scale lack of appropriate research. In addition, the academic circles at home and abroad on the related concepts of urban wetland classification and the consensus has not been formed the scientific conclusion. The lack of theory and the protection management does not reach the designated position, leading to urban wetland area, ecological function degradation or loss, serious of habitat fragmentation, and many other problems, these serious impact on urban ecological environment security.In this paper the effect of urban development problem of urban wetland, combined with the function of urban wetland, preferred on the basis of the research on the integration of urban wetland, clearly define the concept of urban wetland system; Secondly, draw lessons from the wetland classification system, the classification of the urban wetland for scientific foundation of urban wetland system’s success. At the same time, this paper studies the method of establishing urban wetland system and the related parameters, including urban wetland area, urban wetland spatial optimization calculation method.Will combine the theory and practice, in Jinan city wetland system of building as an example, by the history and current situation of urban wetlands research in Jinan, analysis the present situation of Jinan urban wetland on the impact of urban development and the main problems of the urban wetland itself, through constructing the Jinan city wetland system to solve the above problem, and the focus of urban wetland system in Xiaoqing River drainage.Finally, on the basis of literature review and field investigation, combined with the overall planning of Jinan city development, water ecological civilization construction planning, green space system planning requirements, details planning and design an important wetland node in Jinan city wetland system-Huashan wetlands. In the concrete analysis of the status quo of Huashan wetland land, traffic lines, vegetation planting and other details in order to promote Huashan wetland ecology, landscape, culture, recreation and ecological function of harmonious coexistence.
