单木竞争指标在森林可持续经营和森林生态经营方面有很大的实际和理论价值。主要概述了单木竞争指标的概念,研究意义和制定的原则;总结了确定对象木和鉴别竞争木的方法,其中具体描述了鉴别竞争木的固定半径法、树冠重叠法、角规常数抽样法和圆锥调查法;分别归纳了与距离有关和与距离无关的单木竞争指标。与距离有关的方法中主要介绍了KKL方法、树木大小比例法、竞争影响区域法、竞争木株数控制类方法和与树冠有关的方法;阐述了与距离无关的单木竞争指标中的数量化方法即林木相对比和样地面积比例有关的方法。
The single-wood competition index has great practical and theoretical value in sustainable forest management and forest ecological management. The paper mainly summarizes the conception, research significance and principles of single wood competition index, summarizes the methods of identifying wood and distinguishing competition wood, including the methods of fixed radius method, crown overlap method and angle gauge constant sampling method And conic survey method. The single-wood competition index related to distance and distance are summarized respectively. The KKL method, the tree size proportion method, the competitive impact area method, the competition tree number control method and the crown-related method are mainly introduced in the distance-related methods; and the quantitative methods in the single-tree competition index which has nothing to do with distance are described That is, the relative ratio of forest to the plot area.
