林分密度管理图(又称控制图)系根据林分密度效应法编制而成的一种森林经营图.它由等树高线、等直径线、最大密度线、等疏密线、自然稀疏线组成.林分密度管理图主要用来控制林分各生长阶段的立木密度,以达到森林经营的最高经济收益,具有准确、直观、便于使用等优点.随着森林经营集约度的提高,林分密度管理图将逐渐成为确定森林经营类型、定量间伐、资源清查、生长预测和造林设计的重要工具之一.
Forest stand density management chart (also known as control chart) is based on the stand density effect method compiled from a forest management map .It consists of trees such as high line, the same diameter line, the maximum density line, and other dense sparse lines, natural sparse Line composition.The stand density management chart is mainly used to control stand growth density of each stage of forest in order to achieve the highest economic benefits of forest management, with the advantages of accurate, intuitive, easy to use, etc. With the improvement of forest management intensive, Lin Dense density management maps will gradually become one of the important tools for determining the type of forest management, quantitative thinning, inventory, growth forecast and afforestation design.
