Abstract: Atmospheric drought is an important factor affecting vegetation construction,ecological restoration and social-economically sustainable development in the semi-arid sand areas. To understand the spatiotemporal characteristics of drought events in the Mu Us Sandy Land during the past 40 years,this paper estimated the standardized precipitation evapotvanspiration index（SPEI）at monthly,seasonal and annual scales,based on the monthly meteorological data from 1981 to 2020. The results showed that:（1）... More
