摘　　要：具有良好的稳定性是森林持续发挥生态效益的前提,研究森林稳定性具有重要意义。森林持久性是森林稳定性的前提。乔木林是森林的主体,本文选择浙江省东部的台州市和西部的衢州市作为研究区,根据样地优势树种将样地分为松林、杉木Cunninghamia lanceolate林和阔叶林3大优势树种组,利用1994—2019年的森林资源连续清查固定样地数据,从林分存续期数学期望角度入手,进行25年来东、西部乔木林持久性的对比研究。结果表明:(1)无论东部还是西部,阔叶林的持久性最强,松林的持久性最弱;(2)松林的持久性虽然最弱,但都有随着时间推移而增强的趋势,东部更明显;(3)无论哪个优势树种组,东部的持久性明显强于西部;(4)无论东部还是西部,不分树种组,持久性总体都在随着时间推移而增强;(5)林分持久性与林木持久性具有不一致性。Based on the data of the permanent sample plots for continuous forest inventory from 1994 to 2019 in the eastern and western of Zhejiang province,the plots were divided into three groups,namely pine forest,Chinese fir forest and broad-leaved forest according to the dominant tree species.The mathematical expectation of stand duration was used to compare the durability of arboreal forest in the eastern and western Zhejiang.The results show that the durability of broad-leaved forest was the longest in both the East and the West,while that of pine forest was the shortest,but it tended to increase with duration,especially in the East.The durability of every group in the east was obviously longer than that in the west.Both in the east and the west,the arbor forest durability had positive relation with time.
