Groundwater　vulnerability　assessment　is　a　basic　work　for　groundwater　exploitation　and　protection.　The　Chaoyang　district　of　Beijing　was　selected　and　investigated　in　this　study.　Groundwater　vulnerability　index　system　in　Chaoyang　district　was　constructed　based　on　hydrogeological　settings　of　local　region,　the　human　influence　and　the　DRASTIC　model.　The　comprehensive　vulnerability　assessment　was　carried　out　with　weights　of　0.4　and　0.6　for　the　intrinsic　vulnerability　and　the　specific　vulnerability,　respectively.　In　this　study,　total　9　hydrogeological　parameters　were　considered,　and　the　diagram　of　groundwater　vulnerability　assessment　results　in　Chaoyang　District　was　obtained　by　using　DRASTIC　index　and　overlay　weighted　method.　The　groundwater　quality　is　poor　in　the　southwest　of　Chaoyang　District.　The　correlation　analysis　between　total　hardness,　total　dissolved　solids　and　vulnerability　results　was　carried　out,　and　the　correlation　results　were　06　and　0.7,　respectively.　The　area　with　high　groundwater　vulnerability　is　also　the　regions　with　serious　groundwater　pollution,　indicating　that　the　assessment　results　are　objective　and　reasonable,　which　can　provide　prevention　and　control　of　groundwater　reference　for　the　management　department　in　the　future,　so　as　to　reduce　the　risk　of　pollution.　©　2021　The　authors　and　IOS　Press.
