通过对３１个不同种源杉木木材管胞形态因子的数值系统测试，得出各因子的数值均值及变幅。选择造纸性能密切相关的管胞长度、长宽比、壁腔比、柔性系数等性状作为综合评估因子，根据综合坐标法，结合基本密度、生长量性状加以综合评估：湖南会同、湖南江华、福建长汀、江西全南等为相对较优良的杉木种源。
Through numerical system test on the morphological factors of tracheid of 31 different provenance Chinese fir, the mean value and amplitude of each factor were obtained. The synthetical evaluation factors such as tracheid length, aspect ratio, wall cavity ratio, flexibility coefficient and so on, which are closely related to the papermaking performance, were chosen as the comprehensive assessment factors. According to the integrated coordinate method and the basic density and growth traits, comprehensive evaluation was made: Hunan Huitong, Hunan Jianghua, Fujian Changting, Quanzhou, Jiangxi, for the relatively good source of Chinese fir.
