摘　　要：以"近自然林业"为指导思想,对凉水自然保护区不同类型红松林主要树种的重要值进行了研究。结果表明:红松在天然林内并不占据优势地位;红松人工纯林内红松的重要值都很大,都大于同林分内的阔叶树主要树种的重要值之和;林隙透光抚育林内红松的重要值为107.98%,而其他几个阔叶树种色木、白桦、椴树和杨树的重要值相加为121.69%,主要树种中针叶树种和阔叶树种的比值接近1∶1,这种重要值的比率使整个林分的针阔比处于一种平衡的状态。Takingclose to natural forestryas guiding idea ,this articlestudiesthe important value of main tree species of different types of Korean pine forest in Liangshui NatureReserve .The results indicate that Korean pine does not occupy the dominant position in the Korean pinenatural forest ;the important values of Korean pinearelarge in itsartificialpure forest ,wich aremorethan the sum of other broadleaf trees＇important values ;the important value of transparent gaps tending forest is 107 .98% ,while the sum of the other wood ,birch , basswood and several broad -leaved species of poplar important value is121 .69% ,and the ratio of main tree species in the coniferous and broadleaf ratio is close to 1 ：1 ,w hichmakes the stand of coniferous and broad -leaved than in a state of balance .
