摘　　要：燃气是人们生产和生活中不可或缺的要素,而燃气输配运行过程中燃气管网在燃气系统的设计、建设和维护中扮演着至关重要的角色。城镇燃气的高速发展,对燃气管网的运行管理提出了更高的要求,对精细化、科学化、规范化管理需求也不断提升。为满足这些需求,地理信息系统(Geographic Information System,GIS)在城镇燃气地下管网中得到了广泛应用。运用空间数据转换处理系统FME(Feature Manipulate Engine)进行数据建库和数据转换,ArcMAP用于燃气管道设施空间数据处理,GeoPandas结合Sklearn程序包实现巡检网格制作及动态分析可实现地下燃气管道的精细化巡检,进一步提升输配管道设施的运行管理水平,降低事故发生,提高管网运行效率和安全性。Gas is an indispensable element in people's production and life,and the gas pipe network play a crucial role in the design,construction and maintenance of the gas system during the operation of gas transmission and dis⁃tribution.The rapid development of urban gas has put forward higher requirements for the operation management of the gas pipe network,and also increased the demand for refined,scientific and standardized management.In or⁃der to meet these needs,the geographic information system(GIS)has been widely used in urban underground gas pipeline networks.A spatial data conversion and processing system FME(Feature Manipulate Engine)is used for data library construction and data conversion,ArcMAP is used for the spatial data processing of gas pipeline facili⁃ties,and GeoPandas is combined with the Sklearn package to realize the production and dynamic analysis of inspec⁃tion grids,which can achieve the refined inspection of underground gas pipelines,further improve the operation and management level of transmission and distribution pipeline facilities,reduce accidents,and improve the opera⁃tional efficiency and safety of pipeline networks.
