Controlled by the landscape pattern of oasis and desert,the oasis-desert transitional zone is very sensitive to the change of environmental conditons. The processes of wind-blown sand in the oasis-desert transitional zone have direct impact on the stability and development of oasis. Local circulation and microclimate induced by the gradient differences of environment factors between oasis and desert such as vegetation, relief, underlying surface, hydrographic and meteorological factors and so on have restricted the back and forward of desert or the transition of oasis. This paper summarizes the latest research achievements in such six aspects that include local climate, soil erosion, sand storms, aeolian environments, sand transport and prevention system of sand damages. It is expected to solve the problems of sand damages and ensure ecological safety of oasis. Moreover, it will provide scientific evidence for establishing the oasis-protection system in arid region,which is both significant in theory and in practice.
