摘要
[目的]研究湛江市雷林桉树人工林生态价值,讨论人工林生态效益分布趋势。[方法]选定中林集团雷州林业局有限公司桉树林作为研究对象,从涵养水源、固定土壤、碳汇功能、生物多样性、森林景观效益等指标研究人工林生态效益价值。[结果]2019年雷林桉树人工林涵养、保育土壤、固碳价值、制氧价值、生物多样性、森林康养、各林场林木综合生态经济价值分别为56524.66万、13800.11万、1509.601百万、503.200百万、2480.429百万、744.614万、498584.31万元。雷林桉树人工林的生态价值巨大,北坡、纪家与成熟林、近熟林生态价值分别与其的面积、蓄积占比相关,两者在单位上具有相关一致性。生物多样性、固定储碳与制备放氧机制分别与成熟林、幼龄林呈相关一致性。[结论]该研究可为桉树人工林可持续经营利用提供科学依据。
[Objective]To study the ecological value of Eucalyptus plantation in Leilin of Zhanjiang City,and discuss the ecological benefit distribution trend of planted forests.[Method]The Eucalyptus trees of the forest farm of Leizhou Forestry Bureau Co,Ltd.of Zhanjiang Zhonglin Group Leizhou Forestry Bureau Co,Ltd.were selected as the research area to study the ecological benefits of artificial forests from indicators such as water conservation,soil fixation,carbon sink function,biodiversity,and forest landscape benefits.[Result]In 2019,Leilin’s tree plantation conservation,soil conservation,carbon sequestration,oxygen release,biodiversity,forest health and maintenance,and comprehensive ecological and economic value of forest trees in each forest farm were 565.246 million yuan,138011.00 million yuan,150.9601 million yuan,503.200 million yuan,248.290 million yuan,744.614 million yuan,498.584 million yuan respectively.The ecological value of Leylin Eucalyptus plantation was huge.The high ecological value of the northern slope,Jijia and mature forests,and near-mature forests were related to their area and accumulation,and the two were related in unity.Biodiversity,fixed carbon storage,and oxygen release mechanisms were correlated with mature forests and young forests,respectively.[Conclusion]This study can provide scientific basis for sustainable management and utilization of Eucalyptus plantation.
