摘　　要：[目的]明确抚育间伐和施肥综合改培技术措施对江西大岗山地区杉木成龄低质人工林生长、蓄积和经济效益的影响。[方法]对12、14立地指数杉木人工林实施综合改培措施效果效应进行对比,研究综合改培措施对杉木成龄低质林生长、材积和经济效益的影响。[结果]综合改培措施实施2年后,12、14立地指数林分杉木径向生长分别比对照提高了1.45倍和1.67倍,单株蓄积生长量比对照提高了14.3倍和6.0倍。12、14立地指数林分采取综合改培措施的经济效益分别为2 409和293元/(hm^2.a),投入产出比1.00∶1.70和1.00∶1.10。[结论]12立地指数杉木低质人工林采用综合改培措施的近期可获得最高经济效益,在生产中应优先使用。[Objective]To elucidate the effects of thinning and fertilization comprehensive technical measures on mature and low quality Cunninghamia lanceolata planation growth,volume of timber and economic benefits in Dagang mountains region of Jiangxi Province. [Method]The effect of comprehensive improvement measures on 12 and 14 site index Cunninghamia lanceolata plantation was compared and analyzed.[Result]After 2 years＇ implementation of the comprehensive cultivation measures,the radial growth of the 12 and 14 site index stands increased by 1.45 times and 1.67 times than that of the control,respectively,and the accumulative growth of the single plant increased 14.3 times and6 times than that of the control. The 12 and 14 site index had the highest economic benefit,up to 2 409 and 293 yuan/hm^2,and the input-output ratio was 1.00 ∶1.70 and 1.00 ∶1.10. [Conclusion]The comprehensive improvement measures in 12 site index Cunninghamia lanceolata low quality plantation have the highest economic benefit in the near future,and should be used first in production.
