摘　　要：中国桉树人工林的种植规模和特点决定了桉树生态环境影响的研究意义。该文先筛选出环境影响评价指标,再基于生命周期评价(LCA)理论从桉树幼苗的培育,桉树栽种管理,桉树砍伐及枯枝败叶最终处理3阶段来评估桉树整个生命周期内对生态环境的影响,并最终运用货币量化方法估算出1个轮伐期内1 hm^2的桉树人工林对生态环境的影响,得出净效益约为600 000元。为大规模种植桉树人工林的生态影响评估、经济可行性分析及可持续发展战略提供参考。The scale and characteristics of eucalyptus plantation planting determine the significance of studying the impact of eucalyptus＇ life cycle on ecological environment. In this paper, the environmental impact factors of eucalyptus cultivation were screened and the environmental impacts during a tree＇s whole life cycle（from cradle to gate） were monetized quantitatively based on the theory of life cycle assessment（LCA）. The results indicate that a hectare of eucalyptus cultivation during a rotation period could result in the ecological benefit amounting to $600 000 RMB. The study would provide scientific basis for assessing the ecological impact of eucalyptus cultivation.
