【摘要】 调查研究了江西省同一竹龄(Ⅲ度)、不同立地条件下17个天然毛竹林竹材纤维长度、纤维宽度、纤维长宽比、纤维素含量和基本密度等5个主要造纸性能指标,应用统计软件(SPSS13.0)进行多元线性回归分析和偏相关分析,研究其地理变异规律。结果表明:所调查测定的各项指标中,纤维长和纤维长宽比同纬度仅达到10%的显著水平,但与经度和海拔的回归及相关分析都未达到10%显著水平,其余3项指标同经度、纬度和海拔的回归分析均未达到10%显著水平,总体上地理变异模式不明显。更多还原

【Abstract】 Seventeen five-six-year-old Phyllostachys edulis forest under different site conditions in Jiangxi province were selected to study main papermaking characteristics including the fiber length, width, the ratio of length of width, cellulose content and basic density. The multiple linear regression and partial correlation were analyzed with SPSS13.0 software for the law of their geographic variation. The results showed: among the various factors investigated, the fiber length and the ratio of fiber length and fiber width presents the geography pattern which changes along with the latitude, and it has nothing to do with longitude and elevation; the correlation between fiber width, cellulose content, basic density and longitude, latitude, elevation are not notable.更多还原
