大图的存储方式直接影响大图的访问效率以及查询与挖掘的效率。随着大图应用的不断发展，大图分布式存储技术所面临的挑战更加严峻，需要解决的问题日益迫切。首先阐述大图产生的背景以及大图分布式存储所面临的主要挑战，然后分析大图分布式存储技术的国内外研究现状，最后总结现有研究存在的问题并指明未来可能的研究方向。

The storage paradigm of large-scale graph data directly affects the efficiency of graph data access, query and mining.With the development of the applications of large-scale graph data, distributed storage systems for large-scale graph data face more severe challenges. Many problems are very urgent to be resolved. This paper mainly focuses on three issues. Firstly, the background of the generation of large-scale graph data is introduced and the main challenges for distributed storage techniques are stated. Secondly,the state-of-art solutions to distributed storage of large-scale graph data are analyzed. Finally, remaining problems are summarized and possible directions for future research are discussed.
