Study On The Planning Model Of Ecological Network System In Sponge City

Driven by urbanization and industrialization,material conditions and the level of China's economy has undergone a qualitative leap.However,in the process of rapid urbanization but unhealthy long-term environmental problems facing urban waterlogging,runoff pollution,environmental degradation and so on.Therefore,we need an environmental protection measures to ensure the safety of urban drainage and waterlogging under the premise of the maximum to achieve the accumulation of rain in the urban areas,penetration and purification,and promote the use of rainwater resources and ecological environment protection,the design concept of "sponge city" came into being.Built sponges city there should be "sponge" city "sponge" includes both rivers,lakes,waterfront wetland wetlands,including landscape permeable paving,landscaping area roads,urban facilities such as permeable pavement.Which rivers,wetlands and waterfront road landscape green areas are an important part of the ecological landscape corridor city,urban ecological corridor network system and the City "sponge" of construction coincides with the aim to achieve a high degree of unity.This article will specifically ecological landscape corridor construction "sponge" of the study,the first comparative analysis of the domestic and foreign classic case of "sponge City" to interpret the connotation sponges city,constructive and cited the construction of "sponge city".Then discusses the types of urban ecological landscape corridors,function,planning principles and the current problems existing in China's urban ecological corridor;followed by a detailed description of the "rain garden","regulating pond","sunken green space"," the initial rain water abstraction facilities " and other sponge city construction infrastructure measures in the construction of urban ecological corridor in the form.And finally to the author's home Zibo City,"a mountain two rivers" ecological restoration EPC project as an example to carry out a comprehensive and comprehensive research materials,proposed should be used "urban greenway" and "ecological grass ditch" and other green infrastructure in road landscape green belt and the construction of the "river detention pond","river bank buffer","ecological floating island" in one of the Riverside ecological wetland system and other rationalization proposals.And strive to Zibo City ecological landscape corridor construction and Zibo City,"sponge city" construction of a high degree of organic integration for the future of China's urban ecological landscape corridor "sponge" construction to provide a reference value of the application model.
