桉树人工林抚育间伐调控技术研究
收藏资源简介:
为优化人工林空间结构提供新方法,精准提升人工林森林质量,在雷州半岛选取 1 ~ 5 年生短轮伐期桉树纸浆用材林,分析不同林龄的桉树人工林的林分空间结构特征。结合大小比数、角尺度、开敞度、竞争指数和材积等 5 个子目标提出评价指数,并以 Monte Carlo 法建立林分间伐模型,得出最佳采伐方案,从而能精确定位采伐木。
This study proposes a novel method to optimize the spatial structure of plantation forests and accurately improve forest quality. Eucalyptus pulpwood plantations with short rotation ages of 1 to 5 years were selected from the Leizhou Peninsula, and the stand spatial structure characteristics of Eucalyptus plantations at different ages were analyzed. An evaluation index was developed based on five sub-targets, namely size ratio, uniform angle index, stand openness, competition index, and stem volume. Furthermore, a stand thinning model was established using the Monte Carlo method to obtain the optimal harvesting scheme, thus enabling accurate positioning of harvestable trees.
