| 摘 要： | 在民勤干旱荒漠区选择老虎口、青土湖风沙口及关井压田区等5个造林点在不同立地条件下梭梭造林成活率及当年生长量的影响进行了研究。结果表明，不同立地条件对梭梭林的成活率、当年新枝长、树高及地径的影响差异性显著；栽植在不同立地条件类型下梭梭的成活率、当年枝长、苗高和径粗的排序为：老虎口沙区（样地类型Ⅰ）〉关井压田区（样地类型Ⅴ）〉青土湖沙区（样地类型Ⅱ）〉沙区丘间地（样地类型Ⅲ）〉关井压田区（样地类型Ⅳ）.

| Abstract: | Five afforestation sites of Laohukou,Qingtuhu desert and closed pumped well areas and so on were selected in arid desert area of Minqin to study the effects of different site conditions on the survival rate and growth increment of Haloxylon ammodendron forest in the year.The results showed that the effects of different site conditions on the survival rate and new shoot growth in the year,tree height and ground diameter of Haloxylon ammodendron forest had significant difference.Haloxylon ammodendron forest u... |
