英文摘要：

Livelihood vulnerability has become a hotspot research of global environment change and it is also one of the important research paradigms of sustainability science. Firstly, according to the web of science database in 1991-2015 which included the literature of livelihood vulnerability, the article analyzed the livelihood vulnerability＇s distribution status, in terms of time, area, organization etc,by using statistics and visualization.The results show that the quantity of the international livelihood vulnerability research documents are on arising trend, mostly specializing in the subject of ecology, environment, resources and management or other related topics. Five countries（i.e. the United States, the United Kingdom, Australia, Canada, and Germany） and research institutions of University of East Anglia, University of Copenhagen, Mc Gill University, University of Leeds, and University of Sussex show great research strengths of livelihood vulnerability. Secondly, applying the information visualization software Cite Space Ⅲ, this article drew the document co-citation network of livelihood vulnerability, and discussed the knowledge base and core authors. Scholars like Ellis F, Smit B, Adger W N, Kelly P M, Davies Sand Turner B L etc. and their representative works laid a solid foundation in the establishment of the theoretical elementary knowledge and other related researches. Finally, based on the keywords and burst phrases analysis of co-word and word frequency, this article drew the evolution network of livelihood vulnerability research hotspot, and explored the frontier proposition research of famine, political economics, social-ecological system, livelihood strategies, poverty reduction and so on. Because of researcher＇s different situation and various research motives, the research hotspots of livelihood vulnerability are mainly concentrated in the following four categories：1） Residents in ecologically fragile areas are currently being much more dependent on the natural environment and natural
