The Water-Energy-Food(WEF) -Nexus research on urban scale draws more attention since 2014,while the Urban Nexus offers a promising conceptual approach,the use of nexus methods to systematically evaluate water,energy,and food interlinkages or support development of urban socially and politically-relevant resource policies has been limited. A bibliometric analysis using data from Web of Science was carried out to provide a critical review of the literature on Urban WEF Nexus during 1992 - 2017,to depict existing research activities and to identify future directions. The result showed that Urban Nexus research initially ties closely to the research of urban water system,and till now the overall research is still scattered. In 2015 - 2017, four clusters were identified from the keywords networks and Literature community analysis: (1) green infrastructure and urban landscape planning; (2) climate-waterenergy- carbon nexus; (3) waste-water-ecology-health nexus; (4) urban metabolism. Meanwhile,the sustainability and resilience of urban green,gray and blue infrastructure systems; the heterogeneous resource consumption behavior of urban resident' s and its feedback on urban resource system; the framework to produce ' actionable decision support' for multiple users,especially the smart visualization of cross-sectoral trade-offs are of great concern of recent research and will become the key areas for the Nexus paradigm to serve the sustainable development of the future cities. As the lack of adequate data is a common limitation of studies to develop and using robust nexus analysis,data sharing,model selecting and combining platforms are needed to enable collaborative approaches.
