摘要:
[目的]对比中国南北方海绵城市建设差异,以沈阳市为例找出适合北方海绵城市建设的途径。[方法]通过遥感解译、空间分析以及实地访谈等方法,从降水与城市下垫面性质、海绵工程效用、海绵城市成本收益以及公众认知与参与度4个角度来分析沈阳市海绵城市的建设阻碍。[结果]沈阳市海绵城市建设中存在着不透水面激增,海绵工程匹配度低,海绵工程成本高收益缓以及公众参与度低4个方面的主要问题。[结论]海绵城市建设应该与民生工程协同推进,要在助推国家中心城市建设,吸引人口人才流入以及财富增值,拉动投资方面发挥作用,为此,要提高公众海绵城市建设的参与度,对新老城区进行差别化治理,并从政策上保障海绵工程的政府和社会资本合作(public private partnership,PPP)模式的可持续性。

Abstract:
[Objective] The differences of sponge city construction between the north and the south part of China were compared in order to find out the suitable way for the construction of sponge city in the north part of China via a case study in Shenyang City, Liaoning Province.[Methods] Remote sensing interpretation, spatial analysis and field interview were used to analyze of the issues in sponge city construction in Shenyang City from 4 aspects:the precipitation and the characters of urban underlying surface, the utility of sponge projects, the cost-benefit of sponge projects and the public awareness and participation.[Results] There were four main issues in the construction of sponge city in Shenyang City:increasing impervious surface, mismatching between sponge projects and urban waterlogging areas, high costs and low benefits of sponge projects and low public participation.[Conclusion] Sponge city should be constructed in coordination with the civil engineering, and it should play a role in promoting the construction of national central city, attracting the inflow of human resources, increasing wealth and stimulating investment. Therefore, it is necessary to improve the participation of public in sponge city construction, use different methods to governance the suburban and center areas, and ensure the sustainability of public private partnerhip(PPP) madel in sponge city construction.
