Based on physical and chemical characteristics of soils, the estimating models of soil AWC for the Black soils, Cinnamon soils and soils of the main sorts in China were researched by multiple regression and curve simulation in the study.

• 研究中分别以黑土、褐土、区域综合土壤为对象，以收集到的土壤理化性状为基础，采用多元回归方法和曲线拟合的方法，对土壤AWC的估算模型进行了探讨。
