| 摘 要： | 对比分析肉桂不同造林密度对林分地上部分生物量、经济效益的影响效果。结果表明 :随着肉桂林分密度的增大 ,单株生物量逐渐减小 ,林分生物量则逐渐增大 ,达到一定密度后逐步趋于平衡 ;造林密度 6 75 0株·hm-2 时 ,肉桂单位面积利润最高 ,其次是密度 5 6 2 5株·hm-2 ;密度 4 5 0 0株·hm-2 时 ,投资利润率最高 ,其次是密度 5 6 2 5株·hm-2 。

| Abstract: | The results show that single tree biomass decreases gradually with the increase of Cinnamomun cassia stand density,whereas the stand biomass increases gradually,the stand biomass is reaching balance stepwise after a certain density;the C.cassia unit area profit is highest when the afforested density is 6750 trees per hm 2,it’s second highest when the density is 5625 trees per hm 2;the investment profit rate is highest when the density is 4500 trees per hm 2,it's second highest when the density is 5625 trees per hm 2. |
