Under natural conditions and with human activity, the dominance of Oxytropis coerulea become weaker than ever among associations, which reflects a tendency of inverse succession, while those which are less disturbed by human activity show xerosere character because of poor habitat.

在自然条件和人为干扰双重作用下，蓝花棘豆Oxytropis coerulea在群丛中的优势度明显弱化，群丛反映出逆演替趋势，受人为干扰较少的群丛则由于生境条件较差显现旱生演替特征。
