摘要
对椴树红松林和蒙古栎红松林下土壤活性有机碳含量的研究结果表明：两种森林类型下土壤易氧化碳含量均高于土壤微生物生物量碳,且两种活性有机碳含量均表现出随土层加深而降低的趋势;土壤易氧化碳含量,在3个土层中,蒙古栎红松林均高于椴树红松林,且在10~20 cm土层,二者之间差异显著（p〈0.05）。土壤微生物生物量碳含量,在3个土层中,椴树红松林均高于蒙古栎红松林,但差异不显著。土壤易氧化碳、微生物生物量碳、土壤总有机碳之间均达极显著相关。
The amount of soil labile organic carbon in Lime-Korean pine forest and Mongolian oakKorean pine forest was measured in Yichun Fenglin Nature Reserve. The results showed： the amount of soil readily oxidation carbon is higher than the content of soil microbial biomass carbon in both forests,and the amount of soil labile organic carbon will decrease as the soil goes deeper. The amount of soil readily oxidation carbon in Mongolian oak-Korean pine forest is higher than that in Lime-Korean pine forest,and the amount is significantly higher in the 10 ~ 20 cm soil horizons than that in Lime-Korean pine forest（ p 0. 05）. The amount of soil microbial biomass carbon in Lime-Korean pine forest is higher than in Mongolian oak-Korean pine forest in all the three soil horizons,but there is no significant difference. The amount of soil readily oxidation carbon,soil microbial biomass carbon and the total organic carbon show significant correlation.
