【摘要】 本文着重讨论了正常毛竹林分的胸径分布和胸径平均值估计的小样本抽样技术。在对实际林分的调查和分析过程中应用了常见的分布假设检验技术和更高一级的检验方法,得出了:毛竹林分中胸径近似遵从正态分布。这就为小样本抽样提供了依据。用计算机模拟抽样的结果进一步证实了这个结论。更多还原

【Abstract】 The paper has focused its discussion on the normal bamboo stand diameter breast-high ( D.B.H ) distribution and on the average diameter breast-high estimated by a small sample sampling technique. Applying the tests of normal distribution hypothesis and more advanced methods of inspection to the actual investigation and analyzation of the stand, it is shown that the diameter breast-high distribution of bamboo approximately confirms to normal distribution,thus providing the bases for small smaple sampling.The result obtained is further proved by computer simulation smapling.更多还原
