摘　　要：为选择适于彰武小钻杨在沙地生长的立地条件,采用随机区组试验,在章古台沙地对彰武小钻杨不同沙丘部位生长情况进行造林对比试验。结果表明:该沙地彰武小钻杨胸径生长量从大到小依次为丘底、丘间低地、丘腹、丘顶,分别为18.23、17.47、15.06、14.29 cm;树高生长量从大到小排序与胸径生长量相同,分别为12.82、12.22、11.44、9.87 m;彰武小钻杨在不同沙丘部位胸径、树高生长量差异性显著。彰武小钻杨在沙地造林应选择在丘底和丘间低地。In order to select the site conditions suitable for the growth of Populus×xiaozhuanica in sandy land,a random block test was used to compare the growth of Populus×xiaozhuanica at different sand dunes in Zhanggutai sandy land.Result shows that the descending order of the DBH of Populus×xiaozhuanica in this sandy land is the bottom of the mound,the lowland between the mounds,the belly of the mound,and the top of the mound,respectively,being 18.23,17.47,15.06&14.29 cm;the descending order of height growth are the same as the DBH,being 12.82,12.22,11.44,9.87 m respectively;the growth of the DBH&tree height of Populus×xiaozhuanica is significantly different in different sand dunes.Populus×xiaozhuanica should be afforested in the bottom of the mound and the lowland between the mounds in the sand.
