摘 要:本文利用在全省各市县区采集的3 157株编、验表蒙古栎样木数据,对建立吉林省蒙古栎树高级材积表的编制进行了初探。详述了基准树高导向曲线导算、编制方法及树高级材积表编制,探索在低强度工作量基础上,提高测算精度的新思路。The preliminary study on compilation of height advanced volume table of Quercus mongolica in Jilin Province was carried by using 3 157 strains of Quercus mongolica sample data which compiled from the counties and districts of the whole province. The standard height oriented curve calculation,preparation method and height volume table compilation were described. The new ideas for improving measurement accuracy based on low-intensity workload were explored.
