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。
Article through the substantive analysis of the status index table. Based on the generation of homomorphic standard status index table, the problem of cluster-shaped growth of tree height curve was studied. Put forward the concept of multi-type status index and status index function. Based on the analysis of their nature. Finally, the concept of quasi - polymorphism standard position index is put forward. In the sample function space of the status index table of 22 provinces and autonomous regions in China. Using iterative binary nonlinear regression. Generating Polymorphism "standard position index function.It has completed the standardization of the index of status in our country irrespective of region and tree species, and made preliminary attempts to evaluate the index number level in some parts of China.
