| 摘 要： | 为研究不同土壤类型下土壤水分的垂直分布特征及变异情况,在位于黄土高原水蚀风湿交错带的六道沟小流域选取坝淤土、黄绵土和风沙土3种土壤类型为研究对象,测定了0-600cm土壤水分含量,利用经典统计学方法进行分析。结果表明：坝淤土土壤水分剖面呈有规律的波动型变化,黄绵土剖面土壤水分基本呈微弱的波动型变化,风沙土土壤水分剖面变化类型属于降低型;植被覆盖为柠条或小叶杨时,不同土壤类型对0-100cm间土壤水分含量影响不明显,而对100-600cm土壤水分含量影响显著（P〈0.05）;柠条覆盖下0-600cm平均土壤水分均呈现：黄绵土〉坝淤土〉风沙土,小叶杨覆盖下0-600cm平均土壤水分均呈现：风沙土〉坝淤土〉黄绵土;对3种土壤类型而言,同一土壤类型下植被类型的不同主要对深层土壤水分的垂直分布产生影响,总体上,农地和草地下的土壤水分状况好于灌木和乔木。这对于指导干旱区农业生产以及植被恢复中水分的合理调控具有积极的意义。

| Abstract: | In order to identify the vertical distribution and variation of soil moisture in different soil types,the soil moisture along depth of 0-600 cm profile under three soil types in the wind-water erosion crisscross region on the Loess Plateau,i.e.,check dam soil,loessial soil,sandy soil,were measured and analyzed.The results showed that the soil moisture in different soil types exhibited different vertical distribution.The soil moisture in 100-600 cm was affected significantly by different soil types,and the s... |
