In this study, adopting the double loop infiltration method to determination of the soil water infiltration rate in Alar city Tarim University greenlands, and Researching soil bulk density, soil moisture content, soil porosity effect on the rate of soil water infiltration in greenland.The results shows that, the soil infiltration rate decrease rapidly in 0-10min and fluctuate in 10-70min and tends to a stable value in 80-90min.Due to the effect on soil bulk density and soil moisture content, the soil infiltration rate is low, the lowest is 0.03cm/min, negative correlation, And the porosity is positively correlated, the maximum infiltration rate is 1.55cm/min, which makes the different of the soil initial infiltration rate and steady infiltration rate.The results from this study would provide a basis for supervising urban greenlands in Tarim University.%本文采用双环入渗法测定阿拉尔市塔里木大学校园绿地土壤的水分入渗率,并研究土壤容重、土壤含水率、土壤孔隙度对绿地土壤水分入渗的影响.结果表明,土壤入渗率在0~10 min时下降较快;10~70 min时上下波动;到80~90 min时,趋于一个稳定值.由于土壤容重和含水率的影响,使得土壤入渗率较低,最低为0.03 cm/min,呈负相关,与孔隙度呈正相关,最大的入渗率为1.55 cm/min,从而使得土壤的初始入渗率与稳定入渗率差异较大.研究结果为塔里木大学校园绿地的管理提供一定依据.
