红松是珍贵用材树种,红松人工林是重要的后备资源。提高其现有经营管理水平,以培育出更多的优质大径木是摆在我们面前的重要课题。现在采用什么样的密度管理,将采可生产多少株目标径级以上的大径木,这样的产量预测是人们所必需的。产量-密度图的主要特点恰是可以提供目标径级的信息。为此,笔者利 Korean pine is a precious timber species, pine plantation is an important backup resource. It is an important issue before us to increase its existing management level so as to cultivate more high-quality timber. What kind of density management is being used now and how many strains of large-diameter wood of target diameter and above will be produced? Such production forecasting is necessary for people. Yield - The key feature of density charts is precisely the information that can provide the target diameter level. To this end, the author Lee
