摘    要:根据对常规栽培模式的杨树人工林林分生产力分析。确定了各主要立地的培育目标,并计算数量成熟龄、经济成熟龄和工艺成熟龄。分析结果表明:以净贴现值最大确定杨树最优轮伐期,12指数级培育小径材的轮伐期为13-14a,14指数级培育中小径材的轮伐期为12-13a,16指数级培育大中径材的轮伐期为12-13a,18指数级培育大径材的轮伐期为11-12a。表4参2。

关 键 词:杨树  人工林  轮伐期  成熟年龄  抚育间伐  立地条件

Abstract:By analysis of productivity of Populus forest stands cultured innormal patter, breeding aims of various main sites were determinate,and quantitative mature age,economic mature age and process mature age were calculated.The optimum rotation was determinate on basis of the highest VNP.The results were as follows:the rotation of the small diameter timber of Populus cultured in the place with a status index of 12 was 13-14 years,the rotation of the middle and small-diameter timber of Populus cultured in the place with a status index of 14 was 12-13 years.The rotation of large-diameter timber cultured in the place with a status index of 18 was 11-12 years.
