| 摘 要： | 为了获得黄河源区的土壤饱和水力传导度,采用渗透筒法对黄河源区的10个土柱进行了土壤饱和水力传导度的实验室测定.结果表明:黄河源区土壤饱和水力传导度空间变异强烈,各土柱之间饱和水力传导度差别较大;沙性土较之黏性土更适合在实验室测定土壤饱和水力传导度.黄河源区的土壤饱和水力传导度实验室测定值需要在累积出水量达到一定的量后才更为稳定和准确.

| Abstract: | In order to obtain the soil saturated hydraulic conductivity in the source region of the Yellow River,laboratory experiments were conducted on ten undisturbed soil columns in the source region of the Yellow River using the penetration tube method.The results show that the soil saturated hydraulic conductivity in the source region of the Yellow River has significant spatial variation,there are great differences in the saturated hydraulic conductivity between soil columns,and sandy soil is more suitable for laboratory measurement of the soil saturated hydraulic conductivity than clay.The laboratory-measured values of the soil saturated hydraulic conductivity in the source region of the Yellow River in the will be stable and accurate after the accumulated outflow reaches a certain amount. |
