摘要：基于样地实测法和森林固碳计量理论,分析杉阔混交林生态系统各组分的碳储量及分配特征,揭示经营杉阔混交林在固碳增汇方面的潜力优势。结果表明:杉阔混交林从幼龄林到近熟林乔木层碳储量增加了64.97t/hm^2;土壤碳储量增加了18.23t/hm^2。在林龄、密度、立地等相近的情况下,杉阔混交林较杉木纯林的固碳潜力大。杉阔混交林和杉木纯林的林下植被层、凋落物层碳储量差异显著(P<0.05),杉阔混交林在水土保持功能、生物多样性和土壤养分积累等方面更具优势。通过选择合适的混交树种、混交比例和造林密度可以明显增加植被碳储量和土壤有机碳储量,杉阔混交林经营是实现杉木人工林可持续经营的重要途径。
Based on field measurement method and forest carbon sequestration measurement theory,the carbon storage and allocation characteristics of various components in Chinese fir and broad-leaved mixed forests were analyzed,and the management potential advantages of Chinese fir and broad-leaved mixed forests in carbon sequestration were discussed.The results showed that the carbon storage in tree layer of Chinese fir and broad-leaved mixed forests increased by 64.97 t/hm^2 from young forest to near mature forest,and the soil carbon storage increase of 18.23 t/hm^2.In the similar case of forest age,density,site and other circumstances,Chinese fir and broad-leaved mixed forests has greater carbon sequestration potential than pure Chinese fir forest.The carbon storage have an significant difference of understory vegetation layer and litter layer in the Chinese fir and its mixed forests.Chinese fir and broad-leaved mixed forests has more advantages in soil and water conservation function,biodiversity and soil nutrient accumulation.The vegetation carbon storage and soil organic carbon storage can be obviously increased by selecting suitable mixed tree species,mixed proportion and afforestation density.Chinese fir and broad-leaved mixed forests management is an important way to realize sustainable management of Chinese fir plantations.
