摘要:

森林生物量准确测定是科学管理和利用森林生态系统的前提。基于阿尔泰山5个优势树种生物量的实测数据,分别对不同林分的树干生物量、地上生物量、地下生物量及总生物量与实际测量值进行对比,构建了西伯利亚落叶松、西伯利亚红松、西伯利亚云杉、西伯利亚冷杉和疣枝桦的生物量模型。结果表明:W=aDbHc模型为估算阿尔泰山林区5种林分类型生物量的最优模型,并且这5个优势种各器官的生物量大小排序均为树干>树根>树枝>树叶,西伯利亚落叶松林的总生物量最大,对阿尔泰森林生态系统的稳定和发展起着关键的作用。

Abstract:

Accurate measurement of forest biomass is a basis of solving many forest or ecological problems,and also the premise of scientific management and utilization of forest ecosystems.In order to know characteristics of forest biomass in Altai Mountains,five dominant tree species as Larix sibirica,Pinus sibirica,Picea obovata,Abies sibirica and Betula pendula were selected,and the biomass of their trunks,branches,leaves,roots were measured,and biomass model established.The biomass of trunk,aboveground and underground biomass and total biomass of different stands were compared with the actual measured values.The results showed that W=aD bHc was a suitable model in calculating biomass of these 5 tree species.The sequence of biomass of different organs was trunks > roots > branches > leaves.L.sibirica forest has largest biomass,and plays an important role in the stability and development of forest ecosystem in Altai Mountains.

Key words: biomass, model, distribution pattern, Altai Mountains, forest ecosystem, forest ecosystem
