摘要
本文对浙江景宁高演林场19年生的厚朴人工林进行了生物量的研究。结果表明,林分总生物量为71.16t/hm^2,平均净生产量为4.02t/hm^2·a。其中乔木层总生物量和净生产量分别为62.78t/hm^2·a和3.30t/hm^2·a;树皮生物量为6.64t/hm^2,净生产量为0.35t/hm^2·a。
This paper studies the biomass of Magnolia officinalis plantation at 19-old-year in Jingning County. The results showed as follows: The stand had the biomass of 71.16 tons per hectare in which tree stratum and bark made up 62.78 and 6.64 tons per hectare respectively, and had average net production capacity of 4.02 tons per hectare in which the respective value of tree stratum and bark were 3.30 and 0.35 tons per hectare.
