摘　　要：对小黑杨不同密度试验林进行了分析,就短周期纸浆林的造林密度、采伐年龄进行了材积测算和投入、产出的效益分析,确定小黑杨短周期纸浆林的最佳密度和采伐年龄:2 222株.hm-2为12 a;1 111株.hm-2为10 a。Test forest of different density of Populus simonii x P. nigra were analyzed. Volume calculation and benefit analysis of input-output of planting density and cutting age of short-period pulp plantation were conducted. The optimum cutting age is 12 years with the optimum density of 2 222 plant · hm-2. The optimum cutting age is 10 years with the optimum density of 1 111 plant · hm-2.
