In　2001,　a　project　＂A　comprehensive　air　quality　management　study　for　sustainable　development　in　the　City　of　Tangshan,　China＂　was　initiated　aimed　at　developing　effective　air　quality　management　strategies　for　improving　air　quality　in　Tangshan　City.　This　paper　presents　the　results　from　extensive　data　collection　efforts　conducted　in　this　project.　The　comprehensive　investigation　of　urban　air　quality　and　air　pollutant　emission　in　the　study　region　are　introduced.　The　obtained　data　have　been　used　to　address　and　tackle　local　air　pollution　problems　and　identify　complex　interactions　among　local　geographical　features,　social　and　economic　conditions,　meteorological　characters,　emission　sources,　ambient　air　quality,　and　pollution　meteorology.　The　results　could　provide　useful　information　for　the　responsible　authorities　in　determining　which　aspects　of　the　air　pollution　problem　are　deemed　most　important　and　time　critical　by　the　decision　makers.　Some　preliminary　thoughts　and　discussions　on　making　air　quality　management　decisions　presented　at　the　end　of　this　paper　suggest　that　effective　and　efficient　strategies　should　be　pursued　in　setting　future　policy　for　improving　air　quality.
