Abstract: In order to offer new varieties of poplar for arid, semi-arid region afforestation and the “three north areas” shelter belt repairing, 16 varieties of insect-resistant poplar comparison test were arranged in the Ulan Buh Desert Oasis in 2014 April. Based on survey results  of  16 species′ poplar, saving rate, sprouting rate, diameter, height, the new branch length and other factors, single factor analysis, intersection, cluster analysis, comprehensive scoring method were used in  this paper,and eventually selected 7 ecological adaptability and fast-growth poplar species that were relatively good, and give specific sequencing and score, 08-09（59.30）<08-01（61.28）<08-14（61.48）<Jing2（62.06）<16-8（68.52）<16-28（72.68）<16-27（73.09）.

摘要： “三北”防护林退化严重，林分修复补植造林缺乏可供选择的生态适应性强、抗性优良的杨树新品种，尤其在干旱、半干旱区造林树种更加匮乏，加之光肩星天牛危害严重，选择抗性优良的树种亟需解决。基于此，2014年4月在乌兰布和沙漠绿洲布置了16个抗虫杨树品种进行林分修复补植过程中性状的比较，通过对16个杨树品种的保存率、抽梢率、胸径、树高、新梢等因子的调查，用单因子分析、交集法、聚类分析、综合评分的方法最终选出7个生态适应性和速生性均比较优良的杨树品种，并给予具体的排序和分值，08-09（59.30）<08-01（61.28）<08-14（61.48）<京2（62.06）<16-8（68.52）<16-28（72.68）<16-27（73.09）。
