Abstract: Soil infiltration is the process of water penetrating into soils through surface to form soil water, and it is one of the most important indexes to evaluate the capacity of adjusting soil water. This paper introduces the basic concepts, experimental methods and the major influencing factors on soil infiltration. The important functions of soil infiltration in rainflood reduction, groundwater supply, pollutant purification and plant growth are discussed in detail. The situation and influencing factors of soil infiltration in Chinese urban green space are also analyzed. Based on the importance of soil infiltration and insufficient consciousness of most people in China, we put forward four lines of suggestion on the research and application of soil infiltration as follows: (1) Soil infiltration should be taken as an index to evaluate the soil quality of urban green space in China as early as possible, and to improve the soil quality evaluation system. (2) Basic research on soil infiltration of green space should be strengthened. (3) Application of the techniques to improve soil infiltration should be enhanced and the infiltrationimproved integration technology that is suitable for application in China should be developed. (4) Soil construction and maintenance of the greening projects should be changed.
