地位指数曲线是根据树干分析数据建立的，通过线性回归得到地位指数(50年生树龄时的总高度)与前9个5年周期结束时达到的总高度之间的关系。该方法在白云杉、黑云杉、樟子松和马尾松上进行了试验。
Site-index curves were constructed from stem-analyses data with the help of linear regressions derived for relationships between site index (total height at BH age of 50 years, the independent variable) and total heights attained at the end of the previous nine 5-year periods. The method was tested for white spruce, black spruce, lodgepole pine and jack pine.
