地位指数表是当前世界上应用广泛,比较先进的评定有林地生产力的技术方法,它是在林分优势木平均高与林分平均年令的关系上编制的。以其树种规定的年令为标准年令,以其林分优势木标准年令树高的绝对值来表示立地条件优劣的指标,划分为许多不同指数级,它是林地划分立地质量等级的手段,有了地位指数,它将为:森林经营集约化;林业基地规划;森林资源清查中的动态分析;森林主伐、

The status index table is a widely used and advanced method for assessing the productivity of woodland in the current world. It is compiled on the basis of the average high stand of forestry and average year of stand.
