| 摘 要： | 以浙江省为例,提出基于最小尺度的区域生物量估算新方法,包含3方面内容:1)利用二元Weibull生存函数推导二元Weibull分布函数,并用二元Weibull分布函数估算浙江省各径阶、各龄级毛竹的总株数;2)利用已有毛竹胸径、年龄二元单株生物量模型f(D,A),计算各径阶、各龄级毛竹的生物量;3)利用公式MT=∑m i=5 ∑n j=1 kijf(Di,Aj) 实现区域尺度生物量的精确估算.用该方法估算得浙江省毛竹总生物量为1.471 6×1010kg.

| Abstract: | Based on the lowest scale technique,a new method was proposed to accurately estimate Moso bamboo biomass on a regional scale(Zhejiang Province).This method is composed of three steps: 1) A bivariate Weibull distribution function was derived from the bivariate Weibull survival function,and the probability distribution functions of age and diameter classes were developed using the bivariate Weibull distribution function.Then,the total number of moso bamboo culms in terms of each age and diameter class were es... |
