Abstract

The main goal of this research is to show the effects of the interaction among sediment, Aeolian sand and vegetation growth. The critical condition is found when determining the existence of stable interior equilibrium point. Intuitive phase graphs are described for three cases of the consequences of the interaction. The systematic perspective analysis provides an explanation for the dynamic interaction between wind erosion and vegetation growth in arid and semiarid areas.
