| 摘 要： | 本文利用人工草地土壤水分试验资料,分析研究了人工草地土壤水分的周年变化和垂直变化规律,得出草地土壤水分的垂直变化可划分为多变层、过渡层及稳变层;垂直削面的周年变化可分为正常变化期、相对稳定期及变异最大期。

| Abstract: | The paper analyzes the annual and vertical variation of soil moisture in the artificial sward by using the experimental data.The results show that the vertical and annual variation of sward soil moisture can be divided:espectively into three layers and three periods:variable layer, transient layer,and stable layer;normal variation period, relative stable period,and most variable period. |
