摘　　要：柞树是辽东山区的主要阔叶用材树种,在天然次生林的分布中,柞树占据的面积较大,并以蒙古栎和辽东栎为多。为了充分利用该树种的经济价值,对其成熟龄进行初步研究。结果表明:柞树的数量成熟和经济成熟期,均在50年左右;工艺成熟,小径原木和车辕材55年时进入工艺成熟期,一般原木80年后才到来;柞树55年时开始心腐,随年龄增长会逐渐加重.初步认为萌生柞树的主伐龄为50年。Quercus spp .is the main broadleaved timber tree species in Eastern Liaoning Mountains .In the distribu-tion of natural secondary forest ,Quercus spp .occupied large area ;Quercus mongolica ＆amp; Quercus liaotungensis are more .To take full advantage of the economic value of the species ,its mature age was preliminarily studied .Result shows that ：the number of mature age and economic maturity of Quercus spp .all are about 50 years ,and the tech-nology is mature;55-year-old small diameter log ＆amp; cowl timber enter the process maturity ,general logs enter the process maturity after 80 years ;Quercus spp .began to heart rot at 55 year ;heart rot will gradually increase with age .It is regarded that cutting rotation age of germinated Quercus spp .is 50 years .
