摘　　要：在对黑龙江省绥棱林区不同年龄、不同密度及立地因子调查的基础上分别以红皮云杉平均单株生物量、乔木是生物量和乔木层净第一性生产力为基准变量，选取与之相关性强的年龄、密度、郁闭度、海拔、坡度、坡向、土壤Ａ层厚度、土壤有机质含量为说明变量．用数量化模型Ⅰ分析．获得得分表及相关系数表、并同时考虑８个因子的得分范围进行排序．得出影响生物量的主导因子是年龄和郁闭度．而影响净第一性生产力的是密度和年龄。将得分表中得分值最大的类目取出．获得最佳因子组合。The Picea koraiensis artificial forests of different age and different density in Suiling. Heilongjiang Province and their environmental factors were investigated. The average individual biomass of Picea koraiensis. tree layer biomass and tree layer net first productivity are taken as base variation and the age. density. crown density. elevation. slope, exposure, soil thickness of layer A and the organic substance content of soil are taken as illustration factors. The relative coefficients are obtained and the environmental factors are arranged in order respectively. The result shows that the age and the crown density are the key factors affecting the biomass. The density and the age are the key factors affecting the net first productivity. Thus. the best constellation of factors can be obtained.
