摘要
对北京市大兴区京开高速公路永久绿化带毛白杨间伐13年后的生长量和景观效果进行分析。结果表明,毛白杨间伐后单株材积为0.6379 m^(3),比对照增加0.4133 m^(3);蓄积量达415.9 m^(3)/hm^(2)比对照增加146.8 m^(3)/hm^(2).毛白杨间伐后,1.5 hm^(2)试验地可增加碳汇价值0.55×10^(4)元,木材价值17.6×10^(4)元。
The growth and landscape effect of Populus tomentosa of Jingkai Highway green belt in Daxing district of Beijing after thinning for 13 years were analyzed.The results showed that the volume of individual plant was 0.6379 m^( 3) after thinning,which was 0.4133 m^( 3) higher than that of the control(0.2246 m^( 3)).The volume was 415.9 m^( 3)/hm^(2) which was increased by 146.8 m^( 3)/hm^(2) compared to the control.After the thinning of Populus tomentosa,carbon sink value of 1.5 hm^(2) experimental plot would increase by 0.55×10^(4) yuan and timber value would increase by 17.6×10^(4) yuan.
