摘　　要：在昆明市具有代表性的4个公园不同植被类型(乔灌草、灌草、乔草)的不同土层深度(10、20、40、60 cm)下,测定土壤入渗速率及土壤物理性质,分析土壤入渗特征。结果表明:土壤稳渗平均值随土层深度的增加呈现减小的趋势,在不同绿地上表现为乔灌草>灌草>乔草,在不同公园间表现为郊野公园>大观公园>黑龙潭公园>昙华寺公园。稳定入渗速率在不同公园间的差异显著,而在不同深度、不同植被间差异均不显著;最适用于城市绿地土壤入渗过程模拟的是通用公式。随着土层深度的增加城市公园绿地土壤稳渗值逐渐减小,没有明显的中间障碍层,但是在人为活动频繁的公园和乔草植被下,土壤的入渗性能都是最差的。The soil infiltration rate and soil physical properties were measured under different soil depths(10,20,40,60 cm)of different vegetation types(arbor-shrub-grass,shrub-grass,arbor-grass)in 4 representative parks in Kunming.And analyzed the characteristics of soil infiltration.The results show that the average soil infiltration rate shows a decreasing trend with the increase of soil depth.On different green spaces,it shows as follows:arbor-shrub-grass is the largest,shrub-grass is the second,and arbor-grass is the smallest;among different parks,it shows as:the order from largest to smallest is Country Park,Daguan Park,Heilongtan Park,Tanhuasi Park.The difference of stable infiltration rate among different parks is significant,but not significant in different depths and vegetation;the most suitable formula for the simulation of soil infiltration process of urban green space is the general formula.With the increase of soil depth,the steady infiltration value of soil gradually decreases,and there is no obvious middle barrier layer.However,the soil infiltration performance is the worst in parks and arbor vegetation with frequent human activities.
