通过跟踪观测一年生植物层片在一个生长周期内种类组成及其重要值的变化，并分析变化的生态学机理，得出如下结论：①在固沙区草本层片内，小画眉草的多度、盖度和重要值在群落中所占比例较大，是群落优势种；②在充足的降雨后，一年生植物都突发性萌发，但随着降雨的减少，层片内的一年生植物种群都呈衰退之势，其中小画眉草和虎尾草种群急剧减少，狗尾草、雾冰藜和虫实种群减少幅度不大。

We measured morphological and physiological characteristics of C. asiatica in spring 2004 and 2005 at three levels: ramet population, clonal fragment and leaf. Environmental factors of different microsites were investigated again in September 2006.
