Abstract

Here the AA. chose eight inland dry lakes, one outflow lake and one river on the southeast edge of the Inner Mongolian Plateau to investigate vegetation patterns along transects from lake bed to lake shore, and determine the relationships between vegetation patterns and environmental factors. The results show that dry lake bed soils have high contents of fine particles. Also, soil salt content is the most critical control on vegetation succession on desiccated lake beds. The AA. suggest grazing should be avoided around lake shores, especially in Achnatherum splendens communities, because high vegetation cover and biomass not only protect soil from erosion, but also promote the deposition of fine particles blown from upwind regions
