| 摘 要： | 通过对雷州半岛桉树人工林大面积土壤调查研究和多点田间试验,揭示了桉树人工林地力退化的成因,提出了可行的防治措施。其退化成因是桉树人工林生态系统本身的脆弱性、水土流失严重、人为因素对生物积累过程的干扰、桉树全树利用方式、耕垦的不适当以及林地养分收支严重失衡。其防治措施是增加桉树人工林生物多样性、回归林地调落于土壤、应用适当的采伐利用方式和采伐剩余物的处理方式。

| Abstract: | By investigation and field trial, this paper reveals the causes of land capacity degeneration of eucalyptus plantations in Leizhou Peninsula, and put forward the control measures. The causes include the vulnerability of the eucalyptus plantation ecosystems, severe soil and water loss, anthropogenic disturbance to bioaccumulation process, whole-tree utilization way, unsuitable reclamation, and serious imbalance in forest nutrient budget. The control measures are to increase the biodiversity of the eucalyptus plantations, return litter to forest soil, adopt proper falling and utilization ways of trees, as well as proper treating ways of the falling residue. |
