| 摘 要： | 以北京通州区典型农田土壤为研究对象,通过野外采样结合室内试验，用离心机进行土壤水分特征曲线测定，并用van Genuchten模型进行拟合,分析了土壤质地、土地利用、土层深度对土壤水分特征曲线的影响。结果表明，土壤水分特征曲线受土地利用、土层深度影响,而以土壤质地影响最为显著。 |

| Abstract: | This thesis studies the typical physical properties of soil in Tongzhou,Beijing.Through field sampling and laboratory,obtaining the date by using centrifuges and simulating by v-G model,the soil water characteristic curve was compared under the different texture,land use and different depths.The result shows that land use and different depths,especially soil texture,affect the soil water characteristic curve. |
| Keywords: | Tongzhou District Beijing the soil water characteristic curve v-G model factors affecting |
