Many studies have been conducted on the volume reduction and pollutants purification effect of low impact development (LID). However, the comparison between the concentrated infiltration and traditional infiltration of rainfall runoff has been rarely explored. In this study, the difference between concentrated and traditional infiltration mode in sponge cities is analyzed from water infiltration and pollutant purification. Then the infiltration mechanism and the pollutant adsorption, microbial degradation, plant absorption or accumulation processes are compared thoroughly. At last the future development direction of sponge city is also prospected. The conclusion of this study could provide scientific basis and theoretical support for the rational allocation and popularization of rainfall runoff infiltration measures, and promote the healthy development of sponge cities in China.
