Urban　infrastructures　have　the　inherent　characteristics　of　being　interdependent,　which　can　easily　lead　to　cascading　damages　subjected　to　disasters.　Based　on　the　mapping　scientific　literature　software　of　CiteSpace,　this　paper　clarifies　the　historical　development,　the　key　issues,　the　research　hot　spots,　and　the　fundamental　knowledge　of　the　interdependent　infrastructure　system　subjected　to　natural　disasters　via　quantitative　analysis　of　the　literature　obtained　from　the　Web　of　Science.　Furthermore,　the　existing　studies　with　a　particular　focus　on　the　interdependent　water　and　power　supply　networks　are　investigated　and　the　critical　research　focus　and　hot　spots　are　discussed.　Finally,　the　future　trends　and　challenges　in　this　field　are　also　summarized　at　the　end　of　this　paper.　The　research　shows　that　the　main　research　objects　in　recent　five　years　are　natural　gas　networks,　power　grids,　transportation　networks　and　communities.　The　main　disaster　is　earthquake.　The　main　problems　are　recovery,　sustainability,　resilience　and　governance,　and　the　main　method　is　index　method.　The　research　of　interdependent　water　and　power　supply　networks　is　in　a　relatively　important　position　in　the　research　of　interdependent　infrastructures,　and　the　research　literature　accounts　for　about　one　fifth　of　the　retrieved　literature.　In　recent　three　years,　the　hot　spot　in　this　field　is　the　design　of　interdependent　water　and　power　supply　networks　considering　restoration　or　resilience.　©　2021　Science　Press.　All　rights　reserved.
