橡胶树的实验形数在森林资源二类调查计算蓄积量时是一个重要因子。笔者从样地材料计算中发现,小班调查时橡胶树采用的实验形数(0.40)偏大,这与抽样控制调查产生较大的偏差。文中试图通过原因分析后提出纠偏的建议。
The experimental number of rubber trees is an important factor when calculating the stock volume in the second type of forest resources survey. The author found from the plots material calculations that the experimental shape (0.40) used by the rubber tree in the small class survey is large, which is a big deviation from the sampling control survey. The article tries to propose corrective suggestions after analyzing the causes.
