| 摘 要： | 通过马尾松(Pinus massoniana)低效林的改造试验,研究了3种不同改造措施(皆林砍伐重造,补林种植间歇砍伐,纯林措施对照)对地层土壤易氧化有机碳含量的影响,结果表明,易采取相同的改造措施时,随着土层不断加深,不同土壤层的易氧化有机碳含量逐步降低,表现为0～20 cm土壤层>20～40 cm土壤层;同一土壤层...

| Abstract: | Through the transformation experiment of Pinus massoniana low-efficiency plantation,the effects of three different transformation measures(forest clear cutting and rebuilding measure,supplementary forest planting and intermittent cutting measure,pure forest:control)on the content of soil readily oxidizable organic carbon(ROOC)were compared.The results showed that under the same transformation measures,the ROOC content in different soil layers gradually decreased with the increasing of soil layers,and the ROOC content in 0?20 cm soil layer was higher than that in 20?40 cm soil layer.Under the same soil layer,the ROOC content was different under different transformation measures,and the order was shown as:forest clear cutting and rebuilding
