摘　　要：本文主要对取自顺义、菏泽和廊坊三个地区的五年生欧美杨107试样进行了化学成分分析、纤维形态测定及制浆性能研究。结果表明,顺义地区沙土欧美杨107的木素含量较低为21.58%;综纤维素含量最高,为81.02%;在相同的AS-AQ法制浆工艺条件下,卡伯值和K/Y值均最低,分别为17.98和0.341;粗浆得率最高,为52.69%,黏度适中,1112mL/g;制浆性能优于其它欧美杨107试样。The passage mainly classifies 5-year-old Populus x euramericana cv. ＇ 74/76＇ by different regions （ Shu- nyi, Heze,Langfang）, analyzes their fiber morphology, chemical composition and pulping properties. The results show that the Populus x euramericana cv. ＇74/76＇ on the sandy soil from Shunyi possesses the relatively low lignin content and the highest cellulose content, being21.58% and 81.02% respectively; furthermore, at the same AS - AQ cooking condition, its Kappa number and K/Y ratio are the lowest, being 17.98 and 0.341 ,and the pulping yield is the highest, reaching 52.69% , its viscosity of moderate is lll2mL/g. The results indicate that the Populua x eurameri cv. ＇74/76＇ on the sandy soil from Shunyi is a suitable wood for pulping.
