摘要
在全球气候变化和我国城市化进程加快背景下,城市水文环境受到极大的影响,如何对水文过程进行分析,并提出有效的治理措施成为当前的研究热点。结合某典型地区的基础资料,建立了基于暴雨洪水管理模型(storm water management model,SWMM)的城市水文过程模拟模型,通过分析不同频率的降雨情况,对城市排水能力、峰现时间等典型指标变化进行了研究,尤其针对城市排水问题提出了相对应的低影响开发(LID)策略,并给出了模型模拟研究结果。本文的研究结果能够为城市水文分析和城市化建设提供理论依据和技术支撑。
With the global climate changing and urbanization in China,the hydrological environment has been greatly affected. As a result, properly analyze the hydrological process and put forward the effective control measures has become the current research hot topic. According to basic data in a typical area,a model of urban hydrological process simulation is established using SWMM. Through the analysis of various rainfall frequencies,the change of urban drainage capacity,and peak time are studied,especially the low impact development(LID)strategies are proposed. The results of this research can provide theoretical basis and technical support for the analysis of urban hydrology and urbanization.
