摘　　要：在龙江县、富裕县、讷河市等地,对20世纪80年代末90年代初引进和当地选育的杨树品种(品系)进行田间对比试验和测定,利用造林综合评价技术,筛选出适合齐齐哈尔地区生长的中短轮伐期杨树纤维用材林良种青山杨(Populus pseudo-cathayana×P.deltoides)、银中杨(Populus alba×P.berolinensis)和黑青杨(Populus eu-ramericana‘N3016’×P.ussuriensis)等,综合评价指数在2.75～3.00之间,为Ⅰ级,这些品种速生、材性好、抗逆性强、适应范围广,综合指标均好于对照品种小黑杨(Populus simonii×P.nigra)。In Longjiang County, Fuyu County, Nehe City and other places, field comparison test and determination were conducted on the poplar varieties （strains） which were selected in the local and introduced in the late 1980s and early 1990s. Using afforestation comprehensive evaluation technology,mid and short rotation poplar for fiber timber - Populus pseudo-catha yana X P. deltoides, Populus alba X P. berolinensis and Populus euramericana ＇ N3016＇ X P. ussuriensis which are suitable to grow in Qiqihar region were selected; comprehensive evaluation index are among 2.75-3.00, being class I; these varieties have characteristics of fast-growing, good wood properties, strong resistance,wide adaptation,their integrated indicators are better than that of CK （Populus sirnonii XP. nigra）.
