摘　　要：为进一步促进阿拉尔生态城市建设和保证城市可持续发展,以阿拉尔市绿地土壤为研究对象,选取校园、市政、居民区、道路绿化带4个功能区绿地土壤,用环刀法测定土壤水分入渗过程并做了模型拟合和分析。结果表明:4个功能区绿地土壤水分入渗性能存在明显差异,稳定入渗率为道路绿化带绿地(0.31 cm/min)>校园绿地(0.05 cm/min)>市政绿地(0.02 cm/min)>居民区绿地(0.01 cm/min);应用常用的入渗模型进行了拟合,通用模型及Kostiakov模型能较好地描述4个功能区的绿地土壤入渗特征,Philip模型在本区的适用性最差。研究结果为阿拉尔市绿地土壤的管理提供一定依据。In order to further promote the construction of Alar eco-city and ensure the sustainable development of the city, this paper took the urban area of Alar city as the object of study, and selected four types of functional green land soil of the campus, municipal, residential and road greening areas to measure the soil water infiltration process by cutting ring method, and also the model fitting and analysis were made.It is found that there exist evidential differences in soil water infiltration between the four functional green land, and the stable infiltration rates are ranked as road green belt（0.31cm/min） 〉 campus（0.05cm/min） 〉 municipal（0.02cm/min） 〉 residential area（0.01cm/min）;Common infiltration models were adopted to simulate the infiltration progress, and the general model and Kostiakov model are the most suitable to describe the characteristics of soil infiltration in the green land of four functional areas, but the Philip model is not suitable to the study area.The research results provide a basis for soil green management in Alar city.
