求翻译：以年龄、立地、相对密度为自变量，建立林分断面积生长方程。按照林分平均胸径、株数、断面积存在的函数关系及相对密度定义，进一步推导出平均胸径、株数随年龄变化的方程，配合林分形高方程及其他方程编制了木荷人工林标准收获表和经验收获表。是什么意思？

By age, site, the relative density as independent variables, the establishment of stand basal area growth equation. According to the average stand diameter at breast height, number of trees, basal area and there is a function of the relative density of the definition, and further derive the average

By age, location, and relative density of independent variables, and the area ranching establishment growth equation. In accordance with ranching, and average diameter at breast height, the size of the function definition and relative density, and further inferred average diameter at breast height c

Take the age, vertical, the relative density as an independent variable, establishes the Judeich growth of cross-sectional area equation.According to the Judeich average tree diameter at chest height, a number, the sectional area existence functional relation and the relative density definition, fur

With age, site, relative density as the argument, the establishment of stand basal area growth equation. According to the forest with an average diameter at breast height, number of lines, relative density function of the basal area and define further inferred average diameter at breast height, numb

With age, site, relative density as the argument, the establishment of stand basal area growth equation. According to the forest with an average diameter at breast height, number of lines, relative density function of the basal area and define further inferred average diameter at breast height, numb
