In this paper, WRF-Chem (Weather Research and Forecasting model with online coupled chemistry) model is employed to study the future changes of dust emission in Northern China. In order to improve the accuracy of the prediction results, the study comprehensively considers the influence of factors such as aerosols, greenhouse gases and vegetation fraction on the weather, climate and dust emission processes. The prediction shows, from 2016 to 2029, that the amount of dust emission in the northwestern dust source region is higher than that in the northern dust source region, and the differences of topography and climate lead to the differences of dust emission processes and their seasonal variations in the two regions. The seasonal mean dust emission fluxes in the northwestern and the northern from 2016 to 2029 show general decreasing trends, while some seasons show increasing trends. The dust emission flux in the northwestern shows a weak increasing trend in spring, and decreasing trends in summer, autumn and winter. The dust emission flux in the northern dust source region shows decreasing trends in spring, summer and winter, and a weak increasing trend in autumn. The variation trends of dust emission fluxes in the two regions are dominated by near-surface wind speed, while vegetation fraction, precipitation and surface temperature have important effects on the interannual fluctuation of dust emission fluxes.
