摘　　要：对顺义地区五年生的不同家系欧美杨在不同树高下的纤维形态,以及同种家系欧美杨在不同立地条件下的纤维形态进行研究。研究结果表明:(1)沙土条件下,树高1.3m处的纤维形态最好,中林2025的纤维长度为1.124mm,纤维长宽比达到52,较其他欧美杨更好;(2)壤土条件下,树高3.3m处的纤维形态最好,加拿大杨的纤维长度为1.252mm,纤维长宽比达到65,较其他欧美杨更好;(3)四个家系的欧美杨在顺义地区壤土条件下的纤维形态都比沙土条件下的更适合于造纸。Fiber morphology of different families of Populus euramericana of 5 tree-ages by different height of tree was discussed,and same families Populus euramericana by different soils were analyzed.The results show that fiber morphology at 1.3 m height of tree is best in sandy soil,fiber length of Zhonglin 2025 is 1.124mm,the ratio of fiber length to width is 52,they are better than any other Populus Canadensis;fiber morphology at 3.3 m height of tree is best in loam,fiber length of Populus canadensis Moench is 1.252mm,the ratio of fiber length to width is 65,they are better than any other Populus Canadensis;fiber morphology of Populus euramericana in loam is more suitable for papermaking than in sandy soil in Shunyi district.
