摘要/Abstract

摘要： 油松(Pinus tabulaeformis Carr.)占辽宁人工林总面积的30%以上,是辽宁重要后备森林资源。我们于1973—1983年在油松林主要分布区设立了13个定位观测点,按类型区、地位、质量、年龄和初植密度,建立69个区组,314块抚育间伐试验小区,研究油松林间伐效果、间伐技术和经营图表的编制,并从掌握油松林生长与年龄、立木密度之间的数量关系入手,探索以“三元控制”最佳密度管理为核心的间伐技术理论.

Abstract: Pinus tabulaeformis is one of the important reserve forest resourcesin Liaoning Province. From 1973 to 1983,a remarkable result of the intermediate cuttings has been achieved by the fixed-position observation.The volume of standing,crops has been increased by 15—30%,the stand diameter has been expanded by 25%,the matured timer rate has been boosted by 20%,the mature period has been shortened to 10—15% years,and the economic income has been raised by 20—25%. This research also puts forward a mode of quantitatively intermediate cuttings and its theory of "Three-Factor Control" in the intermetiate cuttings procedure of comprehensive reaction;the precision of the ready-made Managing Chart is over 98% (Over 95% for that of inspection).
