摘要
[目的]评价广西桉树人工林生态效益,筛选出能够促进桉树发展的主要技术指标.[方法]通过调查分析广西8个代表性地区的桉树人工林经营发展现状,采用文献查找借阅、实证研究、定量化研究与定性化研究相结合的方法,对广西桉树人工林发展进行生态效益评价.[结果]桉树人工林单项生态服务价值量从小到大依次为净化空气价值、水源涵养价值、固碳释氧价.生态健康价值=固碳释氧价值+水源涵养价值+净化空气价值.广西各地区桉树人工林生态健康价值平均为16.51万元/(hm2·a).[结论]该研究可为更好地发展广西地区桉树人工林生态效益提供理论依据.
Abstract
[Objective] To evaluate the ecological benefits of Eucalyptus robusta plantations in Guangxi and to screen out the main technical in-dexes for promoting the development of Eucalyptus robusta.[ Method] By investigating and analyzing the present situation of Eucalyptus robusta plantation management in 8 representative areas of Guangxi, using the methods of literature search, borrowing, empirical research, quantita-tive research and qualitative research, the ecological benefits of Eucalyptus robusta plantations in Guangxi were evaluated.[ Result] The value of individual ecological services of Eucalyptus robusta plantations from small to large followed by the value of clean air, water conservation val-ue, carbon fixation and oxygen release.Ecological health value =carbon fixation and oxygen release value +water conservation value +clean air value.The average ecological health value of Eucalyptus robusta plantations in different areas of Guangxi was 165.1 thousand yuan/(hm2· a). [Conclusion]The study can provide a theoretical basis for better ecological benefits ofE uc alyptus robusta plantations in Guangxi.
