摘要
以“近自然林业”为指导思想，采用实验生态学的方法，经过6a的伐孔实验证实了林隙对红松更新生长的有利作用，确定出树高与林隙孔径比为1∶ 1～4∶ 3时较利于林隙内红松的生长。据此通过理论生态学的方法，得出了5种地位级上单位面积不同白桦高度及白桦─红松经营复合体中白桦株数、林隙个数、林隙孔径、不同直径大小的红松株数及每个林隙中不同大小的红松株数等技术指标，为红松人工用材林的持续经营提供了科学的依据。
Using the manner of experiment ecology, the effect of gap on Korean pine regeneration and growth was proved after 6 years cutting hole experiment. It is profitable to Korean pine growth when the rate of height to gap diameter is 1∶ 1～4∶ 3. According to the rate, birch number, gap number, gap diameter, Korean pine number of different diameter and Korean pine number of different diameter in every gap in unit of different height birch and Korean pine management compound system of five site classes were calculated. These indexes provide scientific base to the sustained management of Korean pine wood plantation.
