材用毛竹丰产林密度效应模型研究

本文采用二因子二次回归正交旋转组合设计方法，对毛竹材用丰产林的密度效应进行定量研究，建立材用毛竹丰产林的产量模型，利用该回归模型对立竹密度和平均胸径单因子产量效应和两因子互作效应进行了分析，结果表明最佳竹林密度４１６２株／ｈｍ２，平均胸径９．６ｃｍ，竹林可获最高产量５３．６６２ｔ／ｈｍ２．

Study on the Model of Density Effect for Bamboo High-yield Timber F

This paper Quantitatively studied the density effect of Phyllostachys pubescens high-yield timber forest with the resign of two factors of quadratic regressive orthogonal rotation, and built yield model for high-yield timber forest, then analysed the single effect of density and even diameter at breast height (DBH), on yield of timber, and the mutual effect of two factors on yield of timber, the results showed that the best density was 4162 per hectare, the optimum diameter at breast height was 9. 6cm, the highest yield of timber would be up to 53. 662 t/hm2.
