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.
