摘要: 埋地天然气管道是城市的重要基础设施之一,天然气管道失效造成的挥发性有机物泄漏一方面会引起灾难性的环境污染；另一方面会造成经济损失和人员伤亡,对国民经济构成严重威胁。随着埋地天然气管道的普及,确保埋地天然气管道平稳、安全、高效地运行已经成为了一项长期的重大任务。在分析常州市埋地天然气管道泄漏的影响因素 (如地面沉降,地裂缝,城市内涝,土壤腐蚀等) 的基础上,借助IDRISI完成了数据库建立和空间分析,为埋地天然气管道的管理和防护提出了相应的对策建议及今后的重点研究方向。Abstract: Buried natural gas pipeline is one of the most important urban infrastructure. Leakage of volatile organic compounds (VOCs) caused by natural gas pipelines’ failure, is not only a disaster of environmental pollution, but also cause economic losses and casualties, and it pose a serious threat to the national economy. With the popularization of buried natural gas pipelines, it has become a long-term and important task to ensure the smooth, safe and efficient operation of buried natural gas pipelines. The influencing factors of buried natural gas pipeline in Changzhou are analyzed, such as land subsidence, ground fissure, city water logging, soil erosion and so on. Database building and spatial analysis are fulfilled with IDRISI, suggestions and future research directions are proposed to the management and protection of buried natural gas pipelines.
