| 摘 要： | 基于14个样地70个样方,运用聚类分析对研究区伊犁绢蒿(Seriphidium transillense)荒漠草地进行退化演替序列划分,并对其退化过程的阶段进行诊断。结果表明,伊犁绢蒿荒漠草地退化过程可以划分为四个阶段,即未退化、中度退化、重度退化和极度退化。随着退化程度的加剧,群落主要植物种的优势地位发生明显变化,其结果与野外观察一致。

| Abstract: | The cluster analysis method has been used to divide the degraded successional series of Seriphidium transillense desert grassland based on 70 plots 14 sample areas,and the mode of degraded course has been diagnosed.The results showed that the successional series of Seriphidium transillense desert grassland might be divided into four stages,namely,non-degraded,moderately degraded severely degraded and extremely severely degraded.With the increase of the degraded degree,the various changes in the dominants of major plant populations are obvious,which are in accordance with the results of wild investigation. |
