摘要
文章采用多重比较、相关分析等方法,研究了广东省内桉树(Eucalyptus sp.)、马尾松(Pinus massoniana)、杉木(Cunninghamia lanceolata)、阔叶混、针阔混这五种主要林分下的土壤A层有机碳含量,并对土壤A层有机碳含量的主要影响因素进行了分析。结果表明:土壤A层的有机碳含量在0.41～90.25g·kg-1,不同林分土壤A层有机碳含量排列为阔叶混>针阔混>桉树>马尾松>杉木;土壤A层有机碳含量与全氮含量呈显著正相关关系。
The methods of multi-comparison and correlation analysis were used to analyzed the content of soil organic carbon in A soil of eucalyptus （Eucalyptus sp. ） , masson pine （Pinus massoniana）, Chinese fir （Cunninghamia lanceolata） , the mixture of broadleaf and conifer-broadleaf stands. And the main factors influencing the content of A layer soil organic carbon were analyzed. Studies show that： A layer of soil organic carbon content of 0.41 -90.25 g · kg^-1. A layer of forest soils of different organic carbon content of the sequence as follows： mixed broadleaved forest 〉 coniferous and broadleaved mixed forest 〉 E. sp. 〉 P. massoniana 〉 C. lanceolata. The significant positive correlations esisted between A layer soil organic carbon content and total nitrogen.
