摘要:

海绵城市建设的本质是城市水系统的重构,明晰海绵城市系统所涉及的水循环过程是海绵城市研究中最根本、最重要的问题。以海绵城市建设区为研究对象,本文定义了海绵城市系统的内涵,明确海绵城市系统的输入项与输出项,探讨了基于海绵城市系统的城市水循环过程,即海绵城市建设区“大气水—地表水—土壤水—管网水—地下水”转化过程。分别从明确海绵城市建设区的降水与污染物输入、掌握典型海绵设施的径流及污染物转化过程、重视排水管网径流监测与汇流特征参数确定、准确分析海绵城市建设区的径流及污染物外排过程、综合评估海绵城市建设的生态与地下水回补效益共5个方面,系统梳理了海绵城市系统的研究现状及未来的研究要点,以期为海绵城市建设的基础理论研究与工程实践提供启发和帮助,促进中国城镇化转型发展。

Abstract:

The essence of the sponge city construction is the reconstruction of the urban water system. The most fundamental and important issue in sponge city research is to clarify the hydrological processes involved in the sponge city system. This study defines the connotation of the sponge city system, analyzes the input and output items of the sponge city system, and discusses the hydrological processes involved in the sponge city system, that is, the transformation processes of the "Five-water" (atmospheric water, surface water, soil water, drainage water, and ground water) in the sponge city construction area. And then the research status and future research points of the sponge city system are systematically summarized from the following five aspects: precipitation and pollutant input, water quantity and quality conversion of sponge facilities, runoff monitoring and flow concentration parameters of drainage pipe network, runoff and pollutant discharge processes, and ecological benefit and groundwater recharge in the sponge city construction area. This study is helpful to the basic theoretical research and the engineering practice of the sponge city construction, as well as to the transformation of urbanization development in China.

Key words: sponge city, urban hydrology, sponge city facilities, urban hydrological cycle, hydrological system
