摘　　要：主要对取自顺义地区的五年生欧美杨品系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,壤土加拿大杨的综纤维素含量最高,为85.89%,Klason木素含量最低为21.45%,长宽比为54。同时壤土加拿大杨的粗浆得率为51.32%,是所有试样中最高的,且K/Y值为0.314,适于制浆,同时相对应的纸张物理性能较好。所以,顺义地区的欧美杨是优良的纸浆材,而且较适合于用AS-AQ法制浆。This passage mainly studies fiveyear Populus ×euramericana from Shunyi region, analyze their fiber morphology, chemical composition and pulping properties. The results showed that the cellulose content of Populous Canadensis Moench the highest, which is 85.89%.Its Klason lignin content is 21.45%, aspect ratio is the highest of all samples, at 54. At the same time the pulping yield reached 51.32 %, K / Y ratio is best suited for pulping. While the physical properties of paper is better. Therefore, The results indicate that the Populous Canadensis Moench is an suitable wood for pulping.
