摘要

对毛乌素沙地南缘不同演化阶段油蒿(Artemisia ordosica)灌丛沙堆进行了调查和统计分析,探讨了演化过程中沙堆形态特征变化及其与灌丛形态间相互关系。结果显示:(1)研究区油蒿灌丛沙堆以发育阶段和稳定阶段主,衰退阶段灌丛沙堆较少。随灌丛沙堆演化,油蒿灌丛高度保持相对稳定,灌丛长轴和沙堆长轴、短轴都显著增大;(2)沙堆的形态参数间存在显著的相关性,其中发育阶段沙堆长轴、短轴和高度之间显著线性相关,且长轴和短轴相对高度增长较快,稳定阶段沙堆3个参数间协同发展到稳定,而衰退阶段沙堆形态参数间相关性下降;(3)除衰退阶段外,沙堆形态参数与灌丛形态参数间有显著的相关关系,其中沙堆长轴与灌丛长轴、沙堆短轴与灌丛短轴、沙堆底面积与灌丛投影面积,均呈显著线性关系。在环境因素作用下,油蒿灌丛沙堆间整体相互协调发展,使其呈现不同形态特征。

Abstract

In this study, the investigation was conducted on the Artemisia ordosica nebkhas, and the relations between the nebkhas and shrub parameters were analyzed. The result showed: (1) the A. ordosica nebkhas of research area were mainly at developing and stabilizing stages. The shrub length, nebkhas length, and width significantly increased with the nebkhas evolvement, while the shrub height kept unchanged. (2) There were good relationships among morphological parameters of A. ordosica nebkhas. At developing stage, the relationship among the nebkhas length, width and height showed linear correlation, and length and width grew relatively rapidly than height. Nevertheless at stabilizing stage, those nebkhas parameters coordinated development to stable by quadratic linear correlation relationships among parameters, however at degrading stage correlation coefficient of nebkhas morphological parameters declined. (3) The morphological parameters of A. ordosica were significantly correlated with that of nebkhas at developing and stabilizing stage, which all showed a significant liner relationship of shrub length and nebkahs length, shrub width and nebkahs width, shrub crown area and nebkhas basal area. Our results indicated that the evolvement of A. ordosica nabkhas was impacted by its coordinated development in the role of environmental factors, which made the morphological characteristics of shrub and nebkhas significant differences among three evolvement stages.

Key words： Artemisia ordosica; nebkhas; morphological characteristics; evolvement stage
