结构化森林经营方法在阔叶红松林中的应用

Application of Structure-based Forest Management in Broadleaved Korean Pine Mixed Forest

介绍了结构化森林经营的基本理论与主要技术,包括数据调查、林分状态特征分析、经营设计以及经营效果评价等,并以东北阔叶红松林经营实践为例,具体介绍了结构化森林经营方法的应用。应用结构化森林经营方法分析表明,经营阔叶红松林林分为次生林状态,经营类型为抚育间伐型,经营迫切性评价等级为比较迫切,经营方向为提高林分的健康水平和顶极树种的优势程度。本次经营调整顶极树种竞争势及树种混交76株,采伐不健康林木122株。经营后效果评价表明:经营强度属于轻度干扰,顶极树种和主要伴生树种红松、杉松、黄波罗、椴树、核桃楸等的优势度较经营前明显上升,林分中健康林木比例明显上升。本次经营达到了经营目标。

The basic theory and technology of the structure-based forest management is introduced and as a example,the application of the structure-based management in broadleaved Korean pine（Pinus koraiensis） stand is described,including data surveying,stand state characteristics analysis,management design and management evaluation.The analysis results by the structure-based forest management method show that the managed stands of broadleaved Korean pine forest is secondary forest;the management type is tending thinning and management urgency is urgent;the management direction is to improve forest health and climax species advantage extent.During this management operation,the climax species competitive potential was adjusted and 122 unhealthy trees were removed.The management evaluation results show that the management intensity is mild interference,the dominance of climax species and main associated species increased significantly,such as Pinus koraiensis,Abies holophylla,Phellodendron amurense,Tilia amurensis,Juglans mandshurica.The proportion of healthy trees in stand significantly increased so that the target of optimizing forest stand is achieved.
