摘　　要：文章通过对地位指数表的实质性分析．从生成同形标准地位指数表出发，对树高生长曲线簇异形的问题进行研究．提出多型地位指数和地位指数函数的概念。在分析它们的性质基础上．最终提出拟多形标准地位指数的概念.在我国22个省区的地位指数表的样本函数空间中．采用迭代的二元非线性回归法．生成具有多形”特征的标准地位指数函数．完成了我国不分地区、树种的地位指数的标准化。并对我国部分地区的标准地位指数级的数量评价作了初步尝试。Based on analysing the essence of site index table. according to the same shape standard site index model. the non-conventional type curves family of tree height growth was analysed. and the concepts of standard multiform site index and site index function were pointed out. From the site index table of 22 provinces in China. the standard site index function with multiform was formed by adopting iterational non-linear dual regression. thereby completed Chinese standardized site index for non-locality and all -trees. It was the first attempt to evaluate the quantity of standard site index of some parts of areas in China.
