基于空间结构优化的马尾松阔叶树混交林模拟采伐

Simulated Cutting for the Mixed Forest of Pinus massoniana and Broadleaved Tree Species Based on Optimized Spatial Structure

摘要: 利用空间结构参数选择采伐木，确定采伐木选择的基本原则，制定以角尺度作为主要调整目标的林分空间结构优化方案。初步选择采伐结构单元，并在此基础上通过综合分析确定出应该采伐的林木，并对采伐后的林分空间结构进行分析。结果表明:基于林分空间结构格局的采伐使得林分整体质量得到提高，优化了林分的空间结构，适用于生态公益林的经营。

Abstract: The spatial structure parameters were applied to select the trees to be cut,to set the basic principles for determining the trees to be cut,and to establish the optimized scheme for forest spatial structure by taking the uniform angle index as the main regulating objective.The structural unit of selective cutting was primarily selected,the trees to be cut were selected based on the comprehensive analysis,and the stand spatial structure after cutting was analyzed.The results showed that the whole stand quality was improved after the cutting because of the optimization of stand spatial structure,and this type of stand spatial structure optimization was suitable for ecological forest management.
