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 m 3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。

Abstract: 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 m×4 m, 4 m×6 m, 6 m×8 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/hm2 was 12-13 years.
