| 摘 要： | 针对国内林业期刊文献中普遍存在的数学模型参数取值不规范的问题，提出林业数学模型的参数取值，应遵循小数位统一和有效数统一的原则，而且有效数统一原则应该成为最高准则；同时还对与这两项原则有关的某些特定林业数表模型中参数的取值和估计问题进行讨论。

| Abstract: | Aimed at the ill-formed parameter values in mathematical models from domestic forestry periodicals, it was claimed that parameter values in forestry mathematical models follow two general principles, unified decimal digits and unified significance digits, and the latter is the highest criterion. In addition, some issues, related to the two principles ,on parameter value and estimation of special forestry mathematical models were discussed. |
