摘　　要：本文对菏泽地区4～7年生不同品系欧美杨进行了纤维形态测定、化学成分分析,研究其制浆造纸性能。结果表明,4年生欧美杨107的木素含量较低,为22.78%;综纤维素含量最高,为79.32%;成浆卡伯值和K/Y值(硬度得率比)均最低,分别为16.3和0.304;得率较高,为53.6%;黏度适中,为1190mL·g-1。4年生欧美杨较其他几种欧美杨试样更适宜制浆。The paper mainly classify 4 to 7 years old Populus×euramericana from Heze region,analyzed their fiber morphology,chemical composition and pulping properties.The results showed that the 4-year-old Populus×euramericana＇Neva＇possesses the relatively low lignin content and the highest cellulose content,being 22.78% and 79.32% respectively;further-more,its kappa number and K/Y ratio（the ratio of kappa number and yeild） were the lowest,being 16.3 and 0.304,and the pulping yield reached 53.6%,its viscosity of moderate was 1 190mL·g-1.The results indicate that 4-year-old Populus×euramerican＇aNeva＇is an suitable wood for pulping.
