基于蓄积生长率的蒙古栎天然次生林抚育间伐研究

以 5 期吉林省森林资源连续清查数据为基础，筛选蒙古栎幼龄林、中龄林和近熟林，划分 5 级蓄积间伐强 度：强度 1（0~10%）、强度 2（10%~20%）、强度 3（20%~30%）、强度 4（30%~40%）、强度 5（40%~ 50%），对比未间伐林分，研究不同龄组林分对不同间伐强度在各观测间隔（5、10、15 和 20 a）的蓄积生长 率的变化规律。Based on five consecutive forest inventory datasets of Jilin Province, Mongolian oak (Quercus mongolica) stands at young, middle and near-mature age classes were selected. The stocking thinning intensities were divided into five levels: Level 1 (0–10%), Level 2 (10–20%), Level 3 (20–30%), Level 4 (30–40%), and Level 5 (40–50%). Taking unthinned stands as the control group, this study investigated the variation patterns of stand volume growth rate for different age classes under varying thinning intensities across four observation intervals (5, 10, 15, and 20 years).

背景概述

该数据集基于吉林省森林资源连续清查数据，针对蒙古栎幼龄林、中龄林和近熟林，设置了5个蓄积间伐强度等级，并与未间伐林分对比，旨在分析不同龄组林分在不同观测间隔下蓄积生长率的变化规律。
