摘　　要：本文旨在探讨位于民勤荒漠区人工梭梭种群的结构与动态特征,文章通过野外调查和数据分析的方法,对在不同立地条件下人工梭梭的数量、生长状况和分布格局进行了研究。研究发现,在不同立地类型,人工梭梭种群表现出明显的差异。固定沙地梭梭种群密度较高,树高和地径较大,呈现集中分布格局;半固定沙地梭梭种群相对均匀分布,而流沙梭梭则表现出较低的种群密度和分散分布格局。This article aims to investigate the structure and dynamic characteristics of the artificial Haloxylon ammodendron populations in the Minqin Desert area.The research employed field surveys and data analysis to study the quantity,growth conditions,and distribution patterns of artificial Haloxylon ammodendron under various habitat conditions.The study revealed significant differences in the artificial Haloxylon ammodendron populations among different habitat types.In the fixed sand Haloxylon ammodendron population,there is a higher density with greater tree height and diameter,exhibiting a clustered distribution pattern.In the semi-fixed sand Haloxylon ammodendron population,the distribution is relatively uniform,while the mobile sand Haloxylon ammodendron population shows lower population density and a dispersed distribution pattern.Additionally,the study also examined the quantity distribution of Haloxylon ammodendron populations of different diameter classes,revealing the characteristic of the population displaying a pyramidal age structure.
