摘 要 ：通过对内蒙古几种乡士杨树生长量、抗旱性、抗寒性、抗盐性的对比试验,初步认为:展枝小青杨、黄花杨生长量较大;内蒙杨、白皮杨、黄花杨抗旱性较强;黄花杨、白皮杨、兴安杨抗寒性及抗盐性较强。用主分量分析法分析,得出内蒙古7种乡土杨树综合适应性由强到弱的顺序为展枝小青杨、黄花杨、二青杨、白皮杨、内蒙杨、青皮杨、兴安杨。展枝小青杨及黄花杨表现出较强的综合适应能力。

Abstract:Through comparative experiment on growth, drought resistance, cold resistance,salt resistance of several indigenous poplars in inner Mongolia, it is shown that the growths of Populus pseudo-simonii var. patula and P. platyphylla var. fiaviflora are faster; the drought resistances of P. intramongolia, P. cana and P. platyphylla var. flaviflora are stronger; the cold resistance and the salt resistance of P. platyphylla var. flaviflora, P. cana and P. hsinganica are stronger. By the method of PCA, the adaptabilities of 7 poplars in dscent order are P. pseudo-simonii var. patula, P. platyphylla var.flaviflora, P. sp, P cana, P. intra mongolia, P. platyphylla var. glauca, P,hisnganica.
