摘要
通过不同密度、不同土壤质地下的杨树生长数据调查收集和主要经济指标调查分析,进行107杨工业原料林经济优化模式分析,确定不同密度、不同立地条件下最优的经济栽培模式。该文充分考虑木材规格与价格、资本利率以及林分衰退等因素,确定了适合本地区的最优栽培模式,可以让经营者更好的把握工业原料林采伐的时机。结果表明:壤土区适宜栽培密度为2m×3m,沙土区适宜栽培密度为3m×4m;考虑木材规格与价格、资本利率以及林分衰退等因素,认为107杨的经济成熟龄7a为最佳采伐时期,此时采伐效益最高。
Through analysis of growth survey data and the main economic indicators of 107 Poplar in the different density and different soil underground, the paper analyzed the 107 Poplar industrial raw material forest economic optimization model to determine the economic optimum cultivation period with different density and different geological conditions. This paper fully considered the factors such as timber specifications and prices, capital interest rates and the decline of the stand, so as to determine the optimal cultivation model suitable for the local area, so that operators could better grasp the timing of the harvest of industrial raw material forest. The results showed that the soil area was suitable for the planting density of 2 ×3 meters, the sand area of suitable planting density is 3×4 meters.Considering the wood and forest decline in capital interest rate and other factors, determine the sandy soil, the economic mature age was 7-year-old by the planting density of 3 ×4 meters, which was also he best cutting age（The optimal cutting age reference of 107 Poplar by planting density 2×3 meters of loam soil）
