Abstract: The safety and environmental issues surrounding oil and gas pipelines have become a focal point of national and social concern. However,legislation about oil and gas pipeline safety and environmental risk monitoring and early warning system is still lacking in China at present——a problem greatly affecting China's urban public safety as well as its economic and social development. Therefore,in order to offer an improved system for pipeline safety,this study begins by comprehensively analyzing the existing laws and regulations of oil and gas pipeline safety and environmental risk monitoring and early warning. Next,the study analyzes the existing construction situation. Third,the study discusses the main regulatory defects and clarifies legal responsibility,attaching the importance of environmental risk monitoring. Finally,this study suggests that by improving the system of supervision and strengthening the pipeline management and other dimensions of corresponding countermeasures, the management laws and regulation systems of China's urban oil and gas pipeline safety can be perfected in the future.
