In this study, four types of mixed and plantations were selected according to the rows-mixing proportions (type Ⅰ: 5:3, type Ⅱ: 6:4, type Ⅲ: 5:5, type Ⅳ: 1:1). The see-mingly unrelated biomass models of and were developed for obtaining biomass values, and the difference and composition of carbon storage in each forest layer and ecosystem were analyzed. The results showed that carbon storage of arbor layer in different stand types was 39.86-50.12 t·hm, the carbon storage of arbor layer inⅠ, Ⅱ and Ⅳ was significantly higher than that in type Ⅲ. The carbon storage of understory was 0.10-0.30 t·hm, with that in type Ⅱ being significantly higher than other types. Carbon storage of litter layer was 4.43-6.96 t·hm, with type Ⅱ and Ⅲ being significantly higher than those of the other types. In the soil layer, carbon storage was 34.97-54.66 t·hm. The carbon storage of soil layer in type Ⅱ was significantly greater than those in the other types. At the whole ecosystem level, carbon storage of type Ⅰ-Ⅳ was 90.43, 108.27, 85.83 and 89.92 t·hm, respectively. Type Ⅱ had significantly greater carbon storage than the other types. The arbor layer and soil layer were the major carbon pools in the ecosystem, which accounted for 43.3%-55.7% and 38.7%-50.5% of the total, respectively. Our results suggested that mixing by six rows of and four rows of was better for future planting.
在本研究中，根据行混合比例选择了四种混交林和人工林类型（类型Ⅰ：5:3，类型Ⅱ：6:4，类型Ⅲ：5:5，类型Ⅳ：1:1）。为获取生物量值，建立了看似不相关的[具体树种1]和[具体树种2]生物量模型，并分析了各林层和生态系统中碳储量的差异与组成。结果表明，不同林分类型乔木层的碳储量为39.86 - 50.12 t·hm，类型Ⅰ、Ⅱ和Ⅳ乔木层的碳储量显著高于类型Ⅲ。林下植被层的碳储量为0.10 - 0.30 t·hm，其中类型Ⅱ显著高于其他类型。凋落物层的碳储量为4.43 - 6.96 t·hm，类型Ⅱ和Ⅲ显著高于其他类型。土壤层的碳储量为34.97 - 54.66 t·hm，类型Ⅱ土壤层的碳储量显著大于其他类型。在整个生态系统水平上，类型Ⅰ - Ⅳ的碳储量分别为90.43、108.27、85.83和89.92 t·hm，类型Ⅱ的碳储量显著大于其他类型。乔木层和土壤层是生态系统中的主要碳库，分别占总量的43.3% - 55.7%和38.7% - 50.5%。我们的结果表明，未来造林中采用六行[具体树种1]和四行[具体树种2]混交更好。
