摘　　要：为丰富漳浦县沙地树种资源,在漳浦下蔡国有防护林场开展铁刀木不同密度造林试验。结果表明:随着造林密度的增加,林分的平均胸径、平均树高和平均单株材积下降,不同密度林分之间的平均胸径、平均树高和平均单株材积差异极显著;随着密度增大,林分蓄积量先增加后减少,造林密度2000株·hm^(-2)林分的蓄积量略高于造林密度1667株·hm^(-2)林分。造林密度1667株·hm^(-2)林分后侧1倍树高处的相对风速最大,造林密度2000株·hm^(-2)林分后侧1倍树高处的相对风速最小。沿海沙地铁刀木初植密度以2000株·hm^(-2)为宜。The afforestation test on different density of Cassia siamea was carried out in Zhangpu Xiacai state-owned shelter field to enrich the tree species resources on Zhangpu County sandy land.The results showed as follows:the afforestation density was in reverse ratio with average diameter,average height and average volume of the stand;the difference was obvious to average diameter,average height and average volume of different density stand;the stand stock increased first and then decreased with the density adding;the stand stock of density 2000 plants per hectare was higher than that of density 1667 plants per hectare;the relative wind speed was the fastest in one double tree height place of posterior side of the density 1667 plants per hectare stand,while that of the density 2000 plants per hectare stand was the slowest.The initial planting density with 2000 plants per hectare of Cassia siamea on coastal sandy land is the most suitable.
