Abstract: To investigate the development and trends in gas pipeline leakage risk assessment technology in China, a bibliometric analysis was conducted using CiteSpace software on 256 relevant articles from the CNKI database. Key aspects analyzed included the annual number of published articles, distribution across journals, author and institution collaboration networks, keyword co-occurrence and clustering, timelines, and emerging keywords to reveal literature distribution, core research strength, technological advancements, and emerging trends in the field. The results indicate that the development of gas pipeline leakage risk assessment in China can be divided into three stages: the embryonic stage, the fluctuating growth stage, and the high growth stage. The number of published articles began increasing in 2007 and peaked in 2023. Researcher collaboration networks remain relatively dispersed, with institutional collaboration primarily regional. The field has evolved from multiple perspectives, focusing on risk assessment methods, disaster-causing factors, and integrity management. Currently, driven by ongoing upgrades to the China 's energy system and advances in data analysis and processing technologies, research on corrosion characteristics and leakage risks of town gas after hydrogen blending, along with multi-source data fusion risk assessment, has become a key focus and emerging trend in gas pipeline leakage risk assessment.
