摘　　要：桉树是南方国家储备林的重要树种,广西是全国的木材生产大省,占全国木材生产总量的1/3,其中桉树面积约200万hm2,占全区人工林面积的25%左右,提供全区约80%的木材,有力支撑了全国的木材供给。然而由于人为的不科学合理的经营模式,引起的桉树林地生物多样性减少、林地土壤肥力下降等生态问题比较突出,制约桉树人工林可持续经营。针对这些问题,结合广西桉树生产实际和桉树科研成果,本文提出了实施桉树人工林沃土保育工程,实现桉树林地可持续经营的决策建议。Eucalyptus was an important tree species of timber strategic reserve bases in southern China.Guangxi was one of the largest timber production provinces in China,which occupied one third of total timber yield in China.Among those,the area ofEucalyptus was about2million hm2,which occupied about25%of the total plantation areas and provided about80%timber in Guangxi.It was powerful to support the timber supply in China.However,due to the artificial and unreasonable management pattern,the ecological problems,such as the decrease of Eucalyptus forest biodiversity and the reduction of forest soil fertility,became prominent and restricted the sustainable management ofEucalyptus plantation.In response to these issues,combined with the production and research results of Eucalyptus,Eucalyptus plantation soil conservation project should be implemented in order to achieveEucalyptus forest sustainable management.
