| 摘 要： | 通过室内不同氯化钠含量土壤的毛管水上升试验,分析了土壤中氯化钠含量对毛管水上升特性的影响.结果表明:随着土壤中氯化钠含量增大,相同入渗时间的毛管水上升高度和地下水补给量越小;入渗结束后,相同距离的土壤含水量减小.经分析,毛管水上升高度和地下水补给量之间存在密切的直线相关关系,二者分别与时间存在密切的幂函数关系.钠离子对... |

| Abstract: | Through indoor experiment on soil capillary water rise,the effect of soil sodium chloride content on capillary water rise characteristics is analyzed.The result shows that with the increase of soil sodium chloride content,the height of capillary water rise and the amount of groundwater supply during the same time increase,respectively,and the soil water content in the same distance decreases after infiltration.Through the correlation analysis,the height of capillary water rise and the amount of groundwater ... |
| Keywords: | soil sodium chloride content capillary water rise characteristic |
