摘　　要：介绍了徐州市田间持水量测定方法,通过对测定成果进行分析,得出该地区田间持水量与土壤质地、土层深度、渗透及退水能力密切相关,其实验数据可应用于徐州市计算土壤灌溉量,确定墒情和旱情评价指标等。The approach for determination of moisture field in Xuzhou Cityis introduced. Based on the measured results, the area of field capacity is closely related to soil texture, soil depth, permeability and water withdrawal capacity. The experimental data can be applied to calculate Xuzhou city soil irrigation amount, determine soil moisture and drought evaluation index etc.
