| 摘 要： | 通过对北京市州区徐辛庄镇土壤剖面水分的研究，得到了京郊平原区粮田的土壤水分垂直变异特征为各层间的变异表现出明显的层次性；土壤水分随着深度的变化呈曲线形式，但随着表层土壤水分的减少，其随着深度的变化近于直线，土壤水分因土壤质地的不同及土体构型的不同而存在着差异，在研究土壤水分垂直变异规律的基础上对不同土层的土壤水分进行了模拟预测。

| Abstract: | In this article,the vertical variable patterns of soil water of field in Beijing suburbs are studied.Soil water is significantly different in different layers.It changes with the depth nonlinearly,but does nearly linearly as the content of soil water decreases.It also changes with the texture of soil and with the structure of soil.On the basis of the study,the soil water of different layers for the decisions of effective soil water management can be accurately predicted. |
