| 摘 要： | 选择5个不同林龄阶段的马尾松(Pinus massoniana)人工林,研究土壤有机碳的含量、碳储量以及有机碳与氮、磷、钾及pH值之间的关系.结果表明:土壤各层含碳率、碳储量均随林龄的增加而增大,8、12、18、22、30年生林分的碳储量分别为151.62、177.64、201.19、216.19、331.60 t/hm2;同一林龄,不同土壤层含碳率与碳贮量,均随土层深度的增加而减少,表现为:0～20 cm＞ 20～ 40 cm＞40～60cm；有机碳与氮、磷、钾之间均呈现极显著相关,与土壤的pH值相关性不显著.

| Abstract: | Five different aged P.massoniana plantations were selected for study on soil organic carbon content,carbon storage,relation between organic carbon with pH and nutrients such as NPK.The results showed that carbon content and carbon storage at each soil layer increased with the age of plantation.The carbon storage of 8,12,18,22 and 30-year stands were 151.62,177.64,201.19,216.19,331.60 t/ha respectively.The carbon content and carbon storage decreased with soil depth in same aged plantation,which were 0-20 cm > 20-40 cm > 40-60 cm.There was a significantly relation between organic carbon with NPK,but not evident with pH. |
