摘　　要：以福建省来舟林业试验场的长期试验及多年观测材料为基础,探讨密度管理方式对马尾松生长的影响效应。结果表明:培育马尾松胶合板材林,初植密度要适当稀疏,同时要注意适时调整林分密度,以适当增加立木中大径木所占的比例,根据试验结果提出培育马尾松胶合板用材林适宜的初植密度范围为1000～1250株·hm-2,主伐时保留密度为750～860株·hm-2。On the basis of long-term experimental and observation for many years in the Laizhou forestry experiamental farm of Fujian Province.Approaching the effects of different planting densities on the growth of Masson Pine,the results showed that,culturing the big-diameter plywood forest,original planting density must be sparse properly paid attention to adjust the stand density simultaneously,proportion of the big-diameter wood would be increased appropriately,According to the results,the reasonable density on Masson Pine was suggested to be between 1000 and 1250 tree·hm^(-2),the final retaining stand tree number was between 750 and 860 stems·hm^(-2).
