摘要
本文阐述了目前桉树人工林的发展现状及人工林存在的稳定性差、生物多样性小、养分水分消耗过度、地力衰退、病虫害以及化感等生态问题,以及人工林经营中存在的若干问题,提出通过改良桉树人工林栽培、育种、森林经理等措施,建立可持续的遗传育种策略和桉树人工林可持续经营的技术体系,为我国桉树速生丰产林的可持续经营提供科学依据。
This paper expounds research progress and ecological challenges facing eucalypt plantations in Chi- na. Key problems discussed include poor stability, reduced biodiversity, inappropriate water and nutrient con- sumption, soil degradation, increasing pest and disease issues ; and plant allelopathy. In addition, some prob- lems in plantation operations are also revealed. From our study of these issues, suggestions are provided on how to improve the ecological situation for such plantations and these include: improvement of euca/ypt planta- tion land preparation and inter- rotation practices, enhanced silviculture and advancing genetic improve- ment. We conclude that fast - growing eucalypt plantation management in China needs to adopt a more scientif- ic approach in order to ensure both business and environmental sustainability will be achievable in the future for the benefit of China.
