摘要: 在实地调查和形态测量的基础上,应用统计学原理和方法,对新疆艾比湖周边白刺沙堆的实测形态参数进行数理统计分析,以分析艾比湖周边白刺沙堆的空间异质性。结果表明,艾比湖周边白刺沙堆的长轴平均长度介于4.5~7 m之间,短轴平均长度介于3~5.5 m之间,沙堆平均高度介于0.5~1 m之间;沙堆长轴、短轴、迎风坡坡长和背风坡坡长之间均具有显著相关性,尤其是长轴长度和背风坡坡长,短轴长度和迎风坡坡长具有高度相关性,沙堆的高度与短轴的相关程度最高。从白刺沙堆各发育阶段形态特征分析,艾比湖东部和东北部桑德库木和鸭子湾北部白刺沙堆处于生长阶段,艾比湖西部阿拉山口附近的白刺沙堆处于发育的衰退阶段。

Abstract: In order to study the spatial heterogeneity of the morphologic feature parameters of Nitraria nebkhas around Ebinur Lake, the statistical theory and the SPSS and Excel software are employed to do descriptively statistic analysis, correlation analysis and regression analysis. The results indicate that the average length of Nitraria nebkhas around Ebinur Lake is from 4.5 to 7 meters; and the short axis is between 3 and 5.5 meters; the average height of the nebkhas is from 0.5 to 1 meters. There are significant relativity between the length of long axis and short axis of nebkhas, and the upward and leeward slope-length, especially between the length of the long axis and the leeward slope-length; the length of the short axis and the upward slope-length have good correlation, the height of nebkhas and the short axis have the best correlation. The nitratria nebkhas in Allah Mountain pass is at the decline of its development, whereas the nitratria nebkhas near SangDeKuMu and YaZiWan are all at the growing stage.

Key words: Nitraria nebkhas, morphologic feature, spatial Heterogeneity, Ebinur Lake
