摘　　要：对营造在不同坡位和造林密度的7a生杂种马褂木林分进行调查分析。结果表明:杂种马褂木适应性强,7a生林分保存率达98%以上;平均单株树高、胸径和立木材积分别为5.21m、5.9cm和0.010 208m3;马褂木单株生长受到坡位和造林密度的显著影响,其在较低密度、下坡生长最优;造林密度对7a生杂种马褂木林分单位蓄积量的影响不明显。The survey with different slope positions and densities was conducted on growth of 7 years old hybrid liriodendron stand. Survival rate of the stand was more than 98%. Individual average of tree height,DBH and volume was 5.21m,5.9cm and 0.010 208m3,respectively. The growth was affected by slope position and density, significantly. Hybrid liriodendron grow well in the conditions of low density and down slope. And,stand volume of per hectare was not significantly affected by density,when the stand was 7 years old.
