摘要
研究了基于海绵城市建设的低影响开发技术(LID)对场地开发前后自然水文状态的复原原理,分析了LID技术的主要功能,即在场地控制中采用源头处理或者分散处理的技术,从而达到增加雨水的蒸发量、渗透量,削减洪峰流量与径流量,延长峰现时间及同时净化雨水等目标。对LID的6项功能列清单,提出了功能列表并分析了功能多边形。对LID技术功能的分析,有助于了解LID的主要功能及LID的本质目标,为推进海绵城市的建设提供参考。
The paper summarized the function of low impact development（ LID） techniques based on the construction of the sponge city,through researching the principle of LID techniques mimicing the predevelopment site hydrology. The results indicated that the LID control site stormwater at the source and in dispersive way increased evapotranspiration and infiltration,decreased peak runoff and runoff volume,extended the time of peak concentration,and purified the stormwater. Moreover,a deep function analysis of LID techniques was conducted and a table of the six functions was listed. The function analysis of LID techniques would help to make a clear understanding to the goals and essence of the LID. The research also provided methods to boost the development of the sponge city.
