This　paper　presents　a　perspective　of　Urban-Airshed　Carrying-Capacity　(UACC)　concept　for　air　pollution　abatement　in　Tangshan　Municipality,　China.　A　3D　Multi-Box　Air　Quality　Prediction　(3DMBAQP)　model　was　developed　for　predicting　daily　average　SO2,　TSP　and　PM10　concentrations　in　each　sub-box　of　different　municipal　Function　Zones　(FZs).　A　6-step　procedure　was　designed　to　determine　the　UACC　levels　for　each　pollutant.　The　abatement　amounts　for　each　zone　can　then　be　obtained.　The　study　results　can　be　used　by　municipal　authorities　to　develop　effective　initiatives　to　allocate　abatement　amounts　among　different　emission　contributors　and　thus　improve　local　air　quality　in　a　long　run.
