摘要
对福建南靖南亚热带侵蚀赤红壤采取不同治理措施后土壤抗蚀性进行研究 ,结果表明 :采取不同治理措施后 ,土壤抗蚀性各项指标均得到一定程度提高 ,不同治理模式的抗蚀性大小顺序为模式 I(南岭黄檀林 ) >模式 II(蜜柚 ) >模式 III(柑桔 )。在进行开发性治理中 ,应该辅以工程措施 ,并改善土壤水肥状况 ,注意保留林下植被 ,增加地表覆盖或敷盖 ,以增加土壤抗蚀性 ,防止土壤进一步退化 ,才能兼顾经济效益与生态效益。
The effects of different harness measures on latertic red soil antierodibility in Nanjing, Fujian in south sub tropic zone were studied. Each indices of soil antierodibility increased to some extent under different measures, with an antierodibility order of model I (Dalbergia balansae Prain)>model II (sweet pomelo)>model III (orange). It suggests that to take proper exploitation harness, the essential supplementary mechanical measures is needed, soil water and fertility status should be improved, and the undergrowth should be reserved to increase the cover of the floor. Thus, the increased soil antierodibility can prevent soil deterioration effective, and both of the economic and ecological profits can be attained.
