摘　　要：针对伐区作业系统层面的人工林采伐作业,确定生物质流的分析方法和分析模型。分别研究南方常见的3种人工林即马尾松林、桉树林和杉木林的采伐系统,利用跟踪观察法进行试验分析,建立相应的生物质材料流动图和跟踪模型。分析结果表明:每公顷获得原木的干物质量以桉树林最大,占立木干物质量的59.16%,达到68 927.05 kg/hm2。在杉木林和马尾松林伐区,原木干物质量分别占立木干物质量的53.35%和53.14%,原木干物质量分别为53 685.05 kg/hm2和50 916.44 kg/hm2。The analysis methods and models for biomass material flows in plantation logging operation systems were established.The biomass material flows in three common southern plantations（Pine,Eucalyptus,Chinese fir）were analyzed and quantified with the biomass material flow tracking-observing model.And the diagrams of biomass material flows were drawn out.The results showed that eucalyptus forests produce the largest amount of dry matter of the logs（peeling）per hm2 forest land,which accounts for 59.16% of the total stumpage dry biomass with a dry matter weight of 68927.05kg.No significant difference exists between Chinese fir and pine forests.In the Chinese fir plantations,the dry matter of the logs（peeling）accounts for 53.35% of the total stumpage dry biomass with a dry matter weight of 53685.05kg.In the pine plantations,the dry matter of the logs（peeling）accounts for 53.14% of the total stumpage dry biomass with a dry matter weight of 50916.44kg.
