摘　　要：分析了太岳山7种典型森林群落土壤有机质和氮素的基本状况,结果表明:不同林型,土壤腐殖质层和淀积层有机质含量均是油松辽东栎混交林最高,分别为4.908g/kg和3.528g/kg;土壤腐殖质层有机质含量油松林最低,为3.959g/kg,淀积层有机质含量山杨林最低,为1.779g/kg;土壤腐殖质层全氮含量,白桦林最高,为0.368%,辽东栎林最低,为0.176%。;土壤腐殖质层速效氮含量华北落叶松林最高,为292.191mg/kg,油松林最低,为167.725mg/kg;土壤淀积层全氮含量油松林最高,为0.277%,油松辽东栎混交林最低,为0.094%;土壤淀积层速效氮含量山杨林最高为200.183mg/kg,油松辽东栎混交林最低,为49.151mg/kg;土壤有机质、全氮及速效氮含量均是上层土壤高于下层。腐殖质层和淀积层土壤有机质含量在各林型间差异均不显著(P>0.05),而全氮和速效氮含量在各林型间的差异均达到极显著水平(P<0.01)。This paper made an analysis on basic condition of soil organic matter（OM）, total nitrogen （TN） and alkaline nitrogen（AN） in 7 typical forest communites in Taiyue Mountains, The results showed that among different forest stands, the OM contents in soil humus horizon（SHH） and soil illuvial horizon（SIH） were both highest in the pine oak mixed forest stand,which were 4.908g/kg and 3. 528g/kg respectively. The minimum value of OM content in SHH occured in pine forest stand was 3. 959g/kg, while that in SIH occured in platyphylla forest stand was 1.779g/kg. The TiN content in SHH was highest in the white birch forest stand, and the value was 0. 368 %, while the minmum value was 0.176 %, which occurred in the oak stand. The AN content in SHH was highest in the North China larch forest stand, and the value was 292. 191mg/kg, while the minmum value was 167. 725 mg/kg that occurred in in the pine forest stand. The TN content in SIH was highest in the pine oak mixed forest stand, and the value was 0. 277%, while that in the pine forest stand was 0.094%, which showed the lowest level. The AN content in SIH was highest in the Davidiana forest stand, and the value was 200.183mg/kg,while that in the pine oak mixed forest stand was 49.151mg/kg, which showed the lowest level. Among all types of forest sands, the contents of OM, TN, AN were all higher in the upper soil than the lower one. The OM contents in both SHH and SIH showed no significant difference （P 〉 0.05）, while the TN, AN contents showed significant difference（P 〈 0.01 ） among different forest types.
