摘　　要：利用森林经理调查资料、野外调查数据和CBM-CFS3模型,对辽东山区日本落叶松人工林生产力进行模拟。结果表明:Richards模型对辽东山区日本落叶松人工林的林龄-蓄积生长模拟效果较好,日本落叶松人工林净初级生产力(NPP)随着林龄增长呈现先增加后降低的趋势,最后趋于稳定状态;林龄为20年左右时,NPP达最大值;日本落叶松地上生物量碳储量随林龄增长呈增加趋势,林龄为50年左右时达最大值。Based on the forest resources survey data,field survey data and the CBM-CFS3 model,the productivity of Larix kaempferi plantation in the mountainous area in eastern Liaoning Province was simulated.The results showed that the Richards model had a good growth simulation effect on the stand age-stock of Larix kaempferi plantation in the mountainous areas in eastern Liaoning Province.The net primary productivity(NPP)of Larix kaempferi plantation increased first,then decreased,and finally stabilized with the increase of the stand age.The NPP reached the maximum value when the stand age was about 20 years.The carbon storage of the aboveground biomass of Larix kaempferi increased with the increase of the stand age.It reached the maximum when the stand age was about 50 years.
