针阔混交林华北落叶松生物量模型及碳储量研究

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2.50~527.20 kg；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39 478.90 kg/hm²，碳储量为20 252.68 kg/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。

Biomass Model and Carbon Storage of Larix principis-rupprechti in Typical Theropencedrymion

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 was 2.50~527.20 kg;Logistic equation was the optimal model to describe L.pricipis-rupprechtii biomass;The total biomass of L.pricipis-rupprechtii was 39 478.90 kg/hm²,and the carbon storage was 20 252.68 kg/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.
