摘　　要：选取6种京津冀地区常见用材树种:杨树、柳树、榆树、刺槐、油松、落叶松等用材树种作为研究对象,首先分不同树种、生长年限确定单株蓄积,进而综合种植密度、出材率、间伐强度等因数,计算不同树种在间伐和主伐时候的木材产量。通过与现地实测数据对比,该计算方法及结果具有一定可行性和参考性。Six common wood species in the Beijing-Tianjin-Hebei region were selected as research objects,Firstly,the accumulation of individual plant is determined by different tree species and growth years.Then,the wood yield of different tree species in the thinning and main cutting times was calculated by integrating planting density,output rate,thinning intensity and other factors.By comparing with the measured data in the field,the calculation method and results are considered to be feasible and referential.
