Land　use　and　land　cover　change　(LUCC)　can　alter　surface　properties,　such　as　albedo,　roughness,　and　vegetation　coverage,　directly　affecting　dust　emissions　and　aerosol　concentrations,　leading　to　variations　in　direct　radiative　forcing　(DRF)　of　dust　aerosols　and　consequently　impacting　the　climate.　This　study　utilized　the　Weather　Research　and　Forecasting　model　with　Chemistry　(WRF-Chem)　to　quantify　the　impact　of　LUCC　in　northern　China　from　2000　to　2020　on　dust　aerosol　DRF.　Results　indicated　that　LUCC＇s　influence　on　shortwave　radiative　forcing　of　dust　was　significantly　greater　than　its　influence　on　longwave　radiative　forcing　and　exhibited　obvious　seasonal　variations.　Overall,　LUCC　can　cause　net　direct　radiative　forcing　to　increase　by　5.3　W　m-　2　at　the　surface　and　decrease　by　7.8　W　m-　2　in　the　atmosphere.　Different　types　of　LUCC　transformation　showed　distinct　impacts　on　dust　aerosol　DRF,　with　the　conversion　from　sparse　vegetation　to　barren　land　had　the　most　significant　effect　on　net　radiative　intensity,　resulting　in　a　decrease　of　8.1　W　m-　2　at　the　surface,　an　increase　of　12.2　W　m-　2　in　the　atmosphere,　and　an　increase　of　4.1　W　m-　2　at　the　top　of　the　atmosphere.　Conversely,　the　conversion　from　barren　land　to　sparse　vegetation　led　to　surface　cooling　and　atmospheric　warming.　These　findings　are　of　great　significance　for　enhancing　our　knowledge　of　the　effects　of　LUCC　on　the　radiative　balance　of　dust　aerosols.
