采用土壤剖面方式研究了九龙山不同林型林下土壤有机质的分布动态及差异，以及植被类型、海拔、郁闭度等影响因子对土壤有机质的影响。结果表明：九龙山不同立地类型土壤有机质含量为8.49~77.29 g/kg，最高的为灌木林，最低的为日本落叶松林；阔叶林下土壤有机质高于针叶林，混交林高于纯林；土壤中有机质含量动态受环境条件影响大，土壤有机质含量与土层深度呈显著负相关，与海拔、郁闭度、土壤结合水含量等呈显著正相关。

Survey by soil profile was made on organic matter distribution and difference in different site types in Jiulong Mountain, Beijing. The results showed that soil organic matter content under different site types varied from 8.49 to 77.29 g/kg, the highest content was under shrub, the lowest under Larix kaempferi forest. Broad-leaved forest had more soil organic matter than coniferous forest, and mixed forest had more than pure forest. Dynamic soil organic matter content was influenced by environmental conditions, and had significant negative relation with the depth of soil layer, but positive relation with elevation, crown density and soil water content.
