摘　　要：按照植被组成差异将泰山森林划分为油松林、赤松林、黑松林、华山松林、侧柏林、栎林、刺槐林、混交林、经济林和草甸共10种植被类型,分类型设置典型样地,并结合生物量经验(回归)模型估计法测算了泰山森林生态系统乔木、灌木、草本、枯落物及土壤各层的碳储量和碳密度。结果表明:泰山森林生态系统总碳储量为240.54×104t,不同植被类型森林碳储量由高到低依次为油松林(85.63×104t)>混交林(57.29×104t)>刺槐林(28.11×104t)>栎林(22.50×104t)>侧柏林(16.75×104t)>赤松林(14.90×104t)>经济林(6.12×104t)>黑松林(3.93×104t)>华山松林(2.75×104t)>草甸(2.55×104t);不同空间层次碳储量所占比率由高到低分别为土壤层(77.52%)、乔木层(20.60%)、枯落物层(1.49%)、草本层(0.22%)、灌木层(0.17%),其中土壤层和乔木层占总碳储量的98.12%,土壤层碳储量约是植被层的3.69倍。泰山森林生态系统总碳密度为202.17 t/hm2,各植被类型中碳密度最大的为刺槐林(310.88 t/hm2),从森林的碳汇功能来讲,刺槐林不仅不能减少面积,而且应成为今后强化经营管理的对象。According to the vegetation composition,we divided the vegetation types of Mount Tai forest farm into ten types,including Pinus tabuliformis forest,Pinus densiflora forest,Pinus thunbergii forest,Pinus armandii forest,Platycladus orientalis forest,Quercus forest,Robinia pseudoacacia forest,mixed forest,economic forest and Meadow.By setting up typical sample plots of different types and combining with the biomass experience model method,we measured and calculated the forestry carbon storage and carbon density of Mount Tai forest ecological system.The results were as follows：The total carbon storage of Mount Tai forest ecological system was 240.54 × 104 t.Forest carbon storage of vegetation types from high to low was Pinus tabuliformis forest（85.63 ×104 t）, mixed forest（57.29 ×104 t）,Robinia pseudoacacia forest（28.1 1 ×104 t）,Quercus forest（22.50 ×104 t）,Platy-cladus orientalis forest（16.75 ×104 t）,Pinus densiflora forest（14.90 ×104 t）,economic forest（6.12 ×104 t）,Pi-nus thunbergii forest（3.93 ×104 t）,Pinus armandii forest（2.75 ×104 t）and Meadow（2.55 ×104 t）.Forest car-bon storage rate of spatial levels from high to low was soil layer （77.52%）,tree layer （20.60%）,litter layer （1.49%）,herbaceous layer（0.22%）,shrub layer（0.17%）.Soil layer and tree layer accounted for 98.12%of total carbon storage.Carbon storage in soil layer was 3.69 times to those in vegetable layer.The total carbon densi-ty of Mount Tai forest ecological system was 202.17 t/hm2 ,and the biggest one was Robinia pseudoacacia forest （310.88 t/hm2）.In terms of the forest carbon sinks function,we shouldn′t reduce the area of Robinia pseudoaca-cia forest,but should be strengthen the operation and management in the future.
