摘　　要：针对城市内涝频发、水资源分布不均等问题,中国已在部分城市开展海绵城市建设试点工作。由于目前试点范围相对局部、量化分析不足等原因,试点城市应对暴雨内涝的能力仍十分有限。故本文选取济南中心城区为案例进行研究,结合当地背景条件,通过数值模拟的方式量化分析城市内易积水点及低影响开发设施应用前后地表径流量的差异性变化,从而细化海绵城市控制指标,为研究区域及其他城市的海绵城市规划提供合理、科学的依据。In response to the recent frequent urban waterlogging events and uneven distribution of water resources in China, some cities have initiated a pilot project of sponge city planning and urban development. However, currently the pilot cities have very limited capabilities to cope with rainstorm waterlogging due to the limited scope of pilot areas and relative lack of quantitative analysis to support the relevant decision making in the process of sponge city development. This paper focuses on the case study of downtown areas of Jinan city. Based on the local geographical conditions, numerical simulations and relevant quantitative analysis are conducted to investigate those urban spots susceptible to waterlogging and the variance in surface runoff before and after the application of tow-impact development facilities so as to refine the control indicators of sponge city development, with the aim of providing reasonable and scientific basis for the sponge city planning of the regions and other cities.
