中文摘要	针对民勤绿洲梭梭人工林天然更新不良现状,从群落天然更新的必要条件出发,通过对种子萌发,幼苗存活与生长所需生态条件的对比研究,对民勤梭梭人工林天然更新生态条件与限制因子进行了分析,结果表明:民勤多年(1971--2002年)平均降水量为116mm,是适宜梭梭生长的区域,但降雨的季节变化却影响到梭梭天然更新的进行;梭梭的更新与所处的立地类型关系密切,不同立地条件下梭梭人工林植株生长,母株结实状况和土壤水分都存在较大的差异,立地类型是影响梭梭人工林更新的另一影响因素
英文摘要	Aiming at the poor regeneration status of artificial Haloxylon ammodendron plantations in Minqin oasis and from the viewpoint of the necessary conditions for their natural regeneration,a comparative study was made on the necessary ecological conditions for the seed germination, seedling survival, and growth of H. ammodendron at different sites, with the limiting factors for the regeneration of artificial H. ammodendron plantations in the oasis analyzed. The annual mean precipitation in the oasis from 1971-2002 was 116 mm, being suitable for H. ammodendron growth, but the seasonal variation of the precipitation affected the natural regeneration of H. ammodendron. Due to the drought climate in winter and spring, soil moisture had a long term deficit before rainy season, and accordingly, the seed germination and seedling emergence rates of H. ammodendron were low. There were great differences in the growth and seed setting of H. ammodendron among different sites, and thus, site type was another factor affecting the natural regeneration of artificial H. ammodendron plantations
