摘　　要：文章以城市轨道交通企业数量体现产业集聚,用Arc GIS分析并生成企业分布热点图,得到地理位置上的集聚,再结合构建产业图谱以完成研究。文章从城市轨道交通产业链出发,沿产业链上、中、下游对城市轨道交通产业进行分析,通过Py2neo调用Neo4j图数据库首次构建知识图谱与产业图谱结合的综合图谱。在图谱中能够清晰地显示出产业链各个环节所包含的企业,企业具有名称和logo等属性,同时还具有查询功能,可以对图中相关节点以及关系进行查询,便于了解城市轨道交通产业各个领域的相关信息,对该行业的发展具有积极作用。In this paper,the number of rail transit enterprises is used to reflect the industrial agglomeration.ArcGIS is used to analyze and generate the hot spot map of enterprise distribution,so as to obtain the geographical agglomeration,and then construct an industrial map to complete the research.Starting from the industrial chain of rail transit,along the upper,middle and downstream of the industrial chain,this paper takes the rail transit industry of Chengdu as an example,and uses Py2neo to call Neo4j graph database to construct a comprehensive graph combining knowledge graph and industry map for the first time.The graph can clearly show the enterprises included in each link of the industrial chain.The enterprises have attributes such as name and logo,and also have the query function.The relevant nodes and relationships in the graph can be queried,which is convenient for understanding the relevant information of various fi elds of the urban rail transit industry and plays a positive role in the development of the industry.
