Résumé partiel
Central Asia is a region with high dust activity frequency and dust aerosol emission.In recent 50 years,under the influence of climate change background and human unreasonable activities,the lake surface of Central Asia Aral Sea has shrunk sharply,forming a large area of dry lake bottom salt desert landscape,becoming an important dust source.Under the strong wind erosion,a large amount of salt dust is released,and transported over a long time and long distance with the air flow,which seriously affects the human health and ecological and environmental safety in the region.Based on meteorological data and multi-source remote sensing data,the long-term abnormal potential of dust activity in the area was obtained by using hybrid single particle integrated trajectory model（HYSPLIT）model,which was based on meteorological data and multi-source remote sensing data,and the long-term abnormal potential of dust activity in the area was obtained,and the regional differences of potential dust diffusion were revealed,The potential diffusion range and main path of dust are defined.The main influencing factors of dust diffusion in dry lake bed in Aral Sea are explained by means of geographic detector and partial correlation analysis.The health effect of dust diffusion in Aral Sea area is quantified by using the Integrated-Exposure Response（IER）model and Poisson regression
