摘　　要：在影响因子的多因子相关分析和主成分分析的基础上 ,采用正交试验设计方法 ,通过立竹度、平均胸径、年龄结构等因素对竹笋产量、竹材产量、竹林收益等指标的影响来研究毛环竹笋用林的丰产结构 ,结果以立竹度为 135 0 0株· hm-2 、平均胸径为 3～ 3.5 cm、年龄结构为 2～ 4 a生各占 1/ 3的林分竹笋产量最高 ;立竹度为 135 0 0株·hm-2 、平均胸径为 3～ 5 cm、年龄结构为 2～ 4 a生各占 1/ 3的林分经济效益最高。Based on the multiple correlation and principal component analysis(PCA),an orthogonal experiment was made.The high-yield structure was studied according to the density,the average diameter at breast-height,the age structure and so on.As a result,when the density was 13 500 plants per hectare,the average diameter at breast-height was 3～3.5 cm,the age groups of 2～4 years shoots covering one-third of the stands.The bamboo shoot output reached the highest and the economic benefits was the best.
