Résumé partiel
Central Asia is one of the important dust aerosol sources in the world,and its ecological environment and air quality issues have been widely concerned by the community.Aerosols can change the radiation and energy balance of the earth-atmosphere system by absorbing and scattering solar radiation,which has a significant impact on the global climate.It is of far-reaching significance to develop the spatiotemporal heterogeneity of aerosols and its relationship with land cover types in Central Asia for understanding the air pollution situation in Central Asia accurately,and it can provide a scientific reference for comprehensive understanding of aerosol optical properties in Central Asia and improvement of atmospheric environment.This study,based on the long-term sequence MODIS aerosols and land cover products,combined with ground-based observation data and meteorological reanalysis data,comprehensively used STL time series analysis,HYSPLIT model and gray correlation methods to systematically analyze the characteristics of aerosol optical depth and land cover types in Central Asia,and explored the comprehensive influence of LUCC on aerosol
