摘  要:
采用标准样方法研究了纳溪区孝顺竹各器官生物量及其分配特征。结果表明:孝顺竹各器官平均生物量从高到低排列为竹秆>竹枝>竹叶>竹蔸>竹根。单株生物量在各龄级上的分布规律为3a(1006.79g)>2a(868.90g)>1a(631.26g)。各龄级地上部分生物量均高于地下部分,地上部分生物量是地下部分10~12.5倍。林分生物量在各龄级上的分布规律为2a(2476.35 kg·hm-2)>3a(1395.24 kg·hm-2)>1a(673.34 kg·hm-2)。以竹高、胸径为自变量,各器官生物量为因变量建立数学回归模型,结果表明除竹根外,其它均以幂函数(W=c DaHb)所拟合的数学模型相关性最高。

摘  要:
The biomass and its distributting characteristics of Bambusa multiplex various organs were measured by the way of standard plot. The results showed that: the biomass of each organ as follows: stems > branches > stump > leaves >root,the individual plant biomass in the age-class was 3a( 1006. 79 g) > 2a( 868. 90 g) > 1a( 631. 26 g). Biomass of aboveground was more than which of underground in the age-class. Stand biomass in the age-class as folows: 2a( 2476. 35 kg·hm- 2) > 3a( 1395. 24 kg·hm- 2) > 1a( 4544. 93 kg·hm- 2).The mathematical regression modeles were built using the bamboo high and diameter at breast height as the independent variables,and biomass of various organs as dependent variable. The mathematical modeles of organs except root fitted by power function( W = c DaHb) had the highest correlation.
