| 摘 要： | 为了对江西省赣江源区内主要土类的抗蚀性能进行研究,测定各土类的有机质质量分数、密度、抗蚀指数、团聚度、团聚状况、分散率、分散系数、结构破坏率和水稳性团聚体含量等抗蚀性指标,进行主成分分析。结果表明,土壤的抗蚀性大小顺序为:山地矮林土(74.67)>黄壤(61.90)>山地黄红壤(47.26)>黄红壤(44.77)>紫色土(39.79)>红壤(28.34)。在红壤、紫色土区域不仅要预防以暴雨为主要侵蚀力的水土流失,而且需采取相应的措施增加地被物覆盖度、减少人为破坏,以及通过施肥等措施增加土壤的抗蚀性,从而减少水土流失;山地黄红壤、黄红壤区域必须对民众做好宣传工作,在开发利用的同时加强人们对生态环境的保护意识,避免边治理边破坏现象一再发生;黄壤和山地矮林土地区,在综合利用时注意保持现有的良好生态环境,尽可能地避免有利于水土流失活动行为的发生;土壤有机质质量分数、团聚度、团聚状况是评价赣江源自然保护区土壤抗蚀性强弱的最好指标。 |
