摘  要：
本研究采用野外调查和实验室分析相结合的方法,对不同间伐强度下的长白落叶松(Larix olgensis)人工林的土壤总有机碳及理化性质特征进行研究,并分析它们之间的相关关系,为更好的管理森林土壤碳库和制定合理的营林措施提供科学依据。结果表明:(1)随着土壤深度增加,各处理土壤总有机碳含量和碳密度均呈显著垂直递减特征,且表层土壤总有机碳含量和碳密度显著高于其他两层(p<0.05)。(2)随着间伐强度的降低,林分密度增加,土壤总有机碳含量和碳密度均呈先减小后增大的趋势,且强度间伐和轻度间伐土壤总有机碳含量及碳密度显著高于中度间伐(p<0.05)。(3)对三种间伐强度下的落叶松人工林进行分析,土壤总有机碳含量及碳密度与土壤全氮呈极显著(p<0.01)正相关。表明土壤碳素与氮素在土壤中转化存在着密切的关系。

摘  要：
In this study,field investigation and laboratory analysis were used to study the characteristics of soil total organic carbon and physicochemical properties of Larix olgensis plantations under different thinning intensities,and to analyze the correlation between them,which provide a scientific basis for better management of forest soil carbon pool and development of reasonable silviculture measures. The results show that:(1)With the increase of soil depth,the total organic carbon content and carbon density of each treatment soil showed a significant vertical decline feature,and the total organic carbon content and carbon density of surface soil were significantly higher than that of the other two layers(p < 0. 05).(2)With the decrease of thinning intensity,stand density increased,soil total organic carbon content and carbon density decreased first and then increased,and the total organic carbon content and carbon density in intermediate thinning and light thinning soil were significantly higher than those in moderate thinning(p < 0. 05).(3)According to the analysis of larch plantation under three thinning intensity,the total organic carbon content and carbon density of soil were positively correlated with soil total nitrogen(p < 0. 01). This indicated that soil carbon and nitrogen had a close relationship in soil.
