摘  要：
基于样地调查和室内分析,比较研究了长白山地区典型的8种森林类型土壤有机碳和全氮的质量分数、碳氮比、碳密度和氮密度的分布特征。结果表明,8种林型土壤有机碳和全氮的质量分数变化范围分别是36.99~70.33、3.14~6.04 g·kg-1,有机碳、全氮质量分数最大的林型均是阔叶混交天然林。红松天然林土壤C/N值最大为15.56,其它C/N值变化范围为10.55~12.19。在土壤垂直剖面上,随着土层深度的增加,土壤的有机碳、全氮质量分数随之递减,土壤密度随之递增。8种林型土壤碳密度是杨树天然林最大,为22.13 kg·m-2,氮密度是落叶松人工林最大,为1.97 kg·m-2;针阔混交人工林的碳密度和氮密度均为最小,分别是12.37、1.11 kg·m-2。

摘  要：
By the field data and laboratory analysis,we investigated and compared the contents and vertical distribution characteristics of soil organic carbon( C),total nitrogen( N),carbon nitrogen ratio( C / N),C density and N density of eight kinds of typical forest types in the Changbai Mountain area. Soil organic C and soil N for the eight forest types varied from36. 99 to 70. 33 g·kg- 1and 3. 14 to 6. 04 g·kg- 1,respectively. The soil organic C and soil N were highest in the broad leaved mixed forest. The ratios of C / N was highest in the natural Korean pine forest( 15. 56). The ratios of C / N in other forest types varied from 10. 55 to 12. 19. In the soil profile,the contents of soil organic C and N generally decreased with the increase of soil depth. On the contrary,soil density increased with the increase of soil depth. The soil organic C density was highest in the natural poplar forest,22. 13 kg·m- 2,soil N density was highest in Larix gmelini plantation,1. 97 kg·m- 2,and soil organic C density and soil N density were lowest in the mixed broadleaf-conifer plantation,12. 37 kg·m- 2and 1. 11 kg·m- 2,repectively.
