本文的目的是为使假定基本分布适合于水平点抽样中得到的直径而建立所需要的理论。水平点抽样在林业中经常采用,因为测量的重点是较大的、更有价值的林木。结果,样本中不相称地包括一些比真实基本分
The purpose of this paper is to establish the theory needed to fit the hypothesized basic distribution to the diameter found in horizontal spot sampling. Horizontal sampling is often used in forestry because the measurement focuses on larger, more valuable trees. As a result, the sample does not include some more than the true base score
