摘　　要：结合陕西省地震应急对专题图产出的要求,通过研究开源GIS平台,在QGIS和PostGIS中实现地震信息的自动获取、影响场生成和专题图的自动产出,并通过与Docker微服务构架结合构建多服务并行运行框架,最终实现基于开源平台的陕西省地震应急专题图自动产出。经测试显示,该系统提高了地震应急专题图出图效率和运行稳定性,并减少了系统开发和运维的成本。Combined with the requirements for seismic thematic mapping in earthquake emergency,this paper realizes the automatic acquisition of seismic information,the generation of seismic influence field and the automatic output of thematic map in QGIS and PostGIS by studying the open source GIS platform,and constructs a multi service parallel operation framework by combining with Docker micro service application container,so as to finally realize the automatic output of seismic thematic map based on the open source platform.The system improves the drawing efficiency and operation stability of seismic emergency thematic map,and reduces the cost of system development and operation and maintenance.
