摘要
通过对元阳县箐口流域的土壤调查,对其土壤进行分类。同时,对土壤理化性质进行分析。结果表明,参照WRB,箐口流域土壤类型主要是暗色土、疏松岩性土、水耕滞水人为土和水耕潜育人为土、低活性强酸土;箐口流域土壤为强酸和酸性土,有机碳含量较高,土壤有较高的阳离子交换量>10 cmol/kg,但缺乏交换性盐基离子,从而导致较低的盐基饱和度,土壤处于不饱和状态。
According to the soil survey in Qinkou basin, the soil in this area was classified and the physiochemical properties of the soil were analyzed. As concluded, with the reference to WRB, the main types of soil in Qinkou basin are andosol, loose lithology soil, hydroponic stag- hie anthrosol, hydroponic gleyie anthrosol and acrisol. Generally, the soil in Qinkou basin is acidic with high organic carbon content and high CEC 〉 10 cmol/kg, but the soil has the lower base saturation. The soft is unsaturated.
