摘　　要：以大兴安岭地区不同林龄综合抚育后的樟子松和落叶松人工林为研究对象,未抚育的人工林作为对照,对林地内枯落物与土壤碳含量进行研究。结果表明:抚育经营对樟子松和落叶松林地土壤碳含量的影响显著(p<0.05);抚育经营对枯落物层碳含量影响较小;抚育经营可以增加土壤碳含量;土壤碳含量与枯落物层碳含量呈显著负相关;抚育样地之间的碳含量相关性高,未抚育样地之间的碳含量相关性高。The litter and soil carbon content in the forest of Pinus sylvestris var.mongolica and Larix gmelinii plantations which were taken after comprehensive tending at different ages in Daxing'an Mountains were studied,and the uncultivated plantations as the control.The results showed that tending management had a significant effect on soil carbon content of Pinus sylvestris var.mongolica and Larix gmelinii plantations(p<0.05);The effect of tending management on the carbon content of litter layer was small;Tending management can increase soil carbon content;Soil carbon content was significantly negatively correlated with litter carbon content(p<0.05);The correlation of carbon content between nurtured sample plots was high,and that between uncured sample plots was high.
