摘　　要：本文探讨了民勤荒漠区内人工梭梭种群的自然更新和人工辅助恢复机理,文章通过调查民勤县荒漠区的概况,采用样地选择的调查方法收集了梭梭种群的相关数据,经过结果分析,发现不同土壤质地中盐碱度含量对梭梭种群的自然更新产生了影响,而灌溉对梭梭种群的水分利用和幼苗存活也有显著影响,最后深入分析了人工辅助恢复与梭梭种群自然更新之间的相互作用,强调了人工辅助恢复措施在增加种群数量和维护种群健康方面的关键作用。This article explores the natural renewal and artificial assisted restoration mechanisms of artificial Haloxylon ammodendron populations in the Minqin desert area.By investigating the general situation of the desert area in Minqin County and using the method of sample site selection,relevant data of Haloxylon ammodendron populations were collected.After analyzing the results,it was found that the salinity and alkalinity content of different soil textures had an impact on the natural renewal of Haloxylon ammodendron populations,Irrigation also has a significant impact on the water use and seedling survival of the Haloxylon ammodendron population.Finally,an in-depth analysis was conducted on the interaction between artificial assisted restoration and natural regeneration of the Haloxylon ammodendron population,emphasizing the key role of artificial assisted restoration measures in increasing population size and maintaining population health.
