摘要: 以木兰林管局北沟林场内典型针阔混交林为对象,对标准地进行详细的调查研究,利用分层切割法和分层挖掘法对华北落叶松生物量进行测定,建立相应的生长模型,并推算林分中华北落叶松的生物量和碳储量。结果表明:针阔混交林中单株华北落叶松单株总生物量的变化范围是2.50~527.20kg;Logistic方程是华北落叶松生物量主要的最优模型;华北落叶松总生物量为39 478.90kg/hm2,碳储量为20 252.68kg/hm2,各器官碳储量分别占总碳储量的57.89%(树干)、16.88%(树枝)、7.66%(树叶)、17.56%(树根)。林分碳储量分配情况为干>根>枝>叶。
英文摘要: A detailed investigation was conducted on the biomass and carbon storage of typical theropencedrymion-plantation in Beigou Forest Farm administrated by Mulan Forest Bureau.The biomass of Larix pricipis-rupprechtii was measured by stratified cutting and layered digging methods.The growth model was established and the biomass and carbon storage of L.pricipis-rupprechtii in forest were calculated.The results showed that the changing range of the total biomass per larix plant in the mixed forest was2.50~527.20kg;Logistic equation was the optimal model to describe L.pricipis-rupprechtii biomass;The total biomass of L.pricipis-rupprechtii was 39 478.90kg/hm2,and the carbon storage was 20 252.68kg/hm2.The ratios of each organ were 57.89%(trunk),16.88%(branch),7.66%(leaf),and 17.56%(root).Carbon storage distribution was in the order of stem>root>branch>leaf in stand.
