Vegetation ecotype tend to be xerophyte and even hyper-xerophyte and finally replaced by annual plant. Community structure and species diversity also decrease as the ecological environment worsen, In this process, the height, coverage and biomass decreases by 56.6%、 80.8% and 74.2% respectively compared to steppe, and the indices of species richness, diversity and evenness decrease by 76.4%、 56.7% and 32.0%, but β diversity indices increase by 14.6 times, especially the decease of species gregariousness and the breadth and overlay of species Niche shows that grassland tend to be more sandy and vegetation retrogression succession take place.

其中，植被生态型逐渐由中旱生向旱生、超旱生过渡，并最终被一年生植被替代；群落结构及多样性呈明显递减规律，到严重沙化阶段，草群高度、盖度、生物量与典型草原相比，下降幅度分别达到56.6%、80.8%和74.2%；物种丰富度、多样性及均匀性分别降低76.4%、56.7%和32.0%；而群落β多样性增长14.6倍，特别是多年生物种群聚度降低和生态位宽度、生态位重叠值的下降，表明草地沙化，植被发生逆行演替。
