The　distribution　patterns　of　human　activities　affecting　groundwater　vulnerability　vary　with　time.　Studying　the　temporal　and　spatial　changes　in　groundwater　vulnerability,　exploring　the　distribution　characteristics　of　each　period,　and　predicting　the　trends　of　development　are　important　to　formulate　an　effective　development　plan　and　reduce　the　risk　of　groundwater　pollution　at　the　same　time.　Based　on　the　hydrogeological　data　as　well　as　humanities　and　social　data　for　2004,　2010,　and　2016　for　the　Chaoyang　District　of　Beijing,　a　comprehensive　evaluation　model　considering　the　human　factors　such　as　the　land　use　types　was　established　using　the　DRASTIC　model.　The　spatiotemporal　pattern　of　groundwater　vulnerability　was　quantitatively　characterized　by　calculating　the　Global　Moran＇s　I　and　Getis-Ord　Gi*　index,　and　the　distribution　characteristics　and　variations　in　groundwater　vulnerability　were　analyzed　by　the　centroid　of　the　G　index　and　the　standard　deviation　ellipse　of　the　study　area.　The　results　indicate　that　in　2004,　2010,　and　2016,　the　areas　of　high　vulnerability　have　gradually　reduced.　The　groundwater　vulnerability　in　the　study　area　shows　a　strong　spatial　aggregation;　high　concentration　areas　are　mainly　distributed　in　the　northeast　and　southwest　regions.　The　vulnerability　of　the　northeast　region　has　been　decreasing　each　year,　while　the　vulnerability　of　the　northwest　region　has　not　changed　much.　The　main　reasons　are　the　land　use　changes　and　the　reductions　in　fertilizer　use.　©　2017,　Science　Press.　All　right　reserved.
