摘　　要：研究了不同抚育措施对杉木纯林、木荷杉木混交林、枫香杉木混交林生长的影响。结果表明:枫香杉木混交林中杉木地径、树高、冠幅分别比杉木纯林提高3.39%、6.42%、6.67%,木荷杉木混交林中杉木地径、树高、冠幅也分别比杉木纯林提高5.08%、5.66%、1.33%;除草+施肥抚育对杉木生长影响效果最佳,经除草+施肥抚育的纯林中杉木地径、树高和冠幅高于对照(不抚育)136.00%,114.92%和107.61%,施肥抚育的高于对照57.20%,24.62%和22.56%,除草抚育的增幅则相对最小;除草+施肥抚育的木荷杉木混交林中杉木地径、树高和冠幅增幅最大,分别达5.00 cm、1.90 m和1.08 m。The effects of different conservation measures on the growth of pure forests of Cunninghamia lanceolata,two mixed forests with Schima superba and Liquidambar formosana were investigated.The results showed that the ground diameter,tree height and crown width of C.lanceolata mixed with L.formosana were increased by 3.39%,6.42%and 6.67%respectively compared with that of C.lanceolata pure forests.And the ground diameter,tree height and crown width of C.lanceolata in mixed C.lanceolata with S.superba were increased by 5.08%,5.66%and 1.33%respectively compared with that of C.lanceolata pure forests.The effect of weeding and fertilization on the growth of C.lanceolata were the best,and the ground diameter,tree height and crown width of C.lanceolata in pure forests with weeding and fertilization were higher than that of control(without fertilization).Ground diameter,tree height and crown spread were 136.00%,114.92%and 107.61%higher than the control(without fertilization),57.20%,24.62%and 22.56%higher than the control in the fertilization,while the increase in the herbicide fertilization was the smallest;Ground diameter,tree height and crown spread of C.lanceolata in the mixed forest of C.lanceolata in the herbicide fertilization had the largest increase,reaching 5.00 cm,1.90 m and 1.08 m,respectively.
