摘要
经过对 1 2个国有林场、 2 7个样地 ,6年生桐棉 (马尾 )松林分蓄积量进行 Q-型聚类分析 ,将桐棉松栽培区域区划成 、 类区 , 类区 6年生林分蓄积量平均值比 类区高 68.2 % 。
The Q cluster analysis is used to study regionalizing cultivation of Pinus massoniana based on six year stand stock in 27 sample areas from 12 state owned forest farms. The study area was divided into two regions, which called Ⅰregion and Ⅱregion. And there is higher productive in I region than that in Ⅱ region.
