Abstract:InordertoexploretheimpactofKaiduRiverinflow,landandwaterresourcesexploitation,
andhydraulicengineeringregulationonthechangesofwaterandsaltbalanceinBostenLakeunderchan
gingenvironments ,thewater-saltbudgetmodelofBostenLakewasconstructedaccordingtothehydrau

Basedonthesystematicobservationdataofmeteorology ,hydrology,salinityandhumanactivitiesfrom
1955to2020 ,theannual,phasedandmultiyearwater-saltbudgetwereanalyzed.Theresultsshow
