| 摘 要： | 对上层林木采取大强度、中强度、小强度抚育,林分郁闭度分别保持在0.60、0.65、0.70左右时的林分生长量进行调查分析,结果表明:大强度抚育林分冠下红松的树高、胸径、蓄积生长量分别是小强度抚育林分的2.26倍、3.24倍和6.50倍;从整个林分蓄积生长量看,采取大强度抚育林分的生长量最高,是小强度抚育林分的1.30倍...

| Abstract: | The upper layer was cut by three tending intensities: high,medium and low degrees,which resulted in 0.60,0.65 and 0.70 canopy densities,respectively.The height,breast diameter and stock of understory Pinus koraiensis with high tending treatment were 2.26,3.24 and 6.50 times higher than those with low tending treatment.According to the whole stock,the biomass of forest with high tending treatment was the highest,which was 1.30 times than those with low tending treatment. |
