摘要
在红皮云杉分布区内,调查和收集大量的数据和资料,运用数理统计分析理论,筛选出土层厚、坡度为主导因子,划分出不同栽植区内主要立地类型组和立地类型,对立地质量进行评价;分析不同立地、年龄的林分生长变化规律,以密度效应为理论基础,建立林分经营密度表。
A great deal of data and information were investigated and collected in the distribution area of Picea koraiensis Nakai.The soil thickness and slope were selected as the dominant factors by mathematical statistics analysis.The main site type groups and site types in different producing areas were divided and the site quality was evaluated.The change law of stand growth at different sites and ages was analyzed.Based on the density effect,the stand management density table was established.
