摘要

土壤侵蚀是三峡库区紫色土坡地土壤退化的主因

并由此造成土壤粗骨沙化和酸化。利用土地特性系列比较法

通过野外调查和室内分析相结合

研究了三峡库区紫色土坡地土壤退化特征

结果表明:(1)与未退化样地相比

不同利用方式和不同坡度段土壤粗化现象明显

表明它们存在不同程度的侵蚀退化。各土地利用类型pH值均有所减少

表征该研究区紫色土向酸性方向发展

特别是园地和菜地。(2)不同利用方式下土壤沙化程度由高到低的顺序是:荒地>建设用地>耕地>草地>林地>菜地>园地。(3)不同坡度段紫色土坡地土壤沙化程度基本随坡度的增加而增大

但>30°坡度段土壤沙化最轻。(4)不同利用方式和不同坡度段土壤粘粒、有机质、全N、碱解氮、全P、速效P、全K、速效K、阳离子交换量、pH值及微量元素之间存在着明显的相关性。
