摘　　要：为了科学确定泗阳地区南方型杨树的适宜采伐期,在同一立地条件下采取3 m×4 m、4 m×6 m、6 m×8 m3种不同密度进行栽植,通过连续12年的生物量和造林成本的核算,分析最佳的投入产出比,以获得最大经济效益作为采伐期依据.结果表明：南方型杨树造林密度208～833株/hm2的最佳采伐期为12～13年.In order to determine the suitable harvesting period of southern type of poplar in Siyang area, at the same site conditions, the author took 3 mx4 m, d mx6 m, 6 mx8 m 3 different density planting, through 12 years of continuous biomass and afforestation cost accounting, analyzed the best input-output than, in order to obtain the maximum economic benefit as the harvesting period basis. The results showed that： the optimum harvesting period of the southern type of poplar planting density 208-833 plant/hm2was 12-13 years.
