摘要
1999年在浙江省仙居县俞坑村的封山育林区设置20m×20m的固定样地2块，对连续5年的调查数据进行统计分析，以其对次生幼林乔木物种结构变化进行研究。分析结果，乔木层物种丰富度指数增加了7—11，乔木物种增加了2—5科，3—8属。自然恢复为以壳斗科、杉科、山茶科、樟科、胡桃科、安息香科等物种为建群种或夹建种的次生常绿阔叶林、针阔混交林。
Two fixed sample plots of 20m × 20m were set up in enclosure area of Yukang village in Xianju county in Zhejiang in 1999 to statistically analyze the inventory data within successive 5 years, and to study arbor species structural changes of secondary young-aged forest. As a result, abundance index of species had increased 7-11, and the number of arbor species had grown 2-5 families, 3-8 genera. Natural regeneration was secondau evergreen broadleaf forest, mixed coniferous and broad-leaf forest which was mainly composed of Fagaceae, Taxodiaceae, Theaceae, Lauraceae, Juglandaceae and Styracaceae.
