摘要
1997年在福建省福安市甘棠镇眉洋村的15年生马尾松人工林中进行不同抚育间伐强度试验,2001年进行调查,结果认为,在一定范围内,其胸径生长随间伐强度增大而增大;增大抚育强度增加单株材积,但单位面积蓄积量减少;不同抚育强度对林分总收获量无显著影响。
A set of experiments on diverse intensive effect were conducted in 15 - year old Pinus massoniana planted forest of Meiyang village, Gantang township of Fuan city, Fujian province in 1997. The survey in 2001 indicated that breast diameter grew greatly with enlarging intermediate cutting within certain scope; and increased intensity of tending could increase single timber volume, but stocking in unit area decreased; and diverse tending intensity had no obvious impact on total stand harvest yield.
