Influence of Artificial Oasis on Evolution Trend of Sandstorm in Tarim Basin and Policy Countermeasures from 2000 to 2022

Sandstorm is the most serious disaster suffered by human settlements in arid areas. From the perspective of human activities, this paper analyzes the influence of artificial oasis change on spatial variation in sandstorm disaster and its driving mechanism, and summarizes the evolution of sand control policy centered on human activities, so as to provide a reference for sandstorm prevention and ecological environment control in arid areas. The results show the following: (1) The spatial distribution of sandstorm disasters in Tarim Basin presents a clear pattern of “two core source areas dominate, spread along mountains and basins, and weaken significantly in oasis”. Artificial oasis scale and green vegetation area showed significant spatial inhibition effects on sandstorm disasters. (2) With the strengthening of human activities and sand control policies and systems, the intensity of sandstorms in Tarim Basin showed a significant trend of westward movement and contraction. (3) Human activities, such as population scale, economic level, artificial green vegetation and grassland area, have significant correlation effects on the intensity of sandstorms.
