 摘要： Tongliao City is located in the alluvial plain of the West Liao River, where short-duration heavy precipitation occurs frequently in summer, and urban waterlogging has become the main meteorological disaster affecting the safe and sustainable development of the city. Based on the geographical location, topography and climate characteristics of Tongliao City, the causes of urban waterlogging were analyzed from natural factors, urban development, infrastructure and management systems. According to local infrastructure construction, the risk of urban waterlogging was classified based on waterlogging characteristics, and the distribution characteristics of urban waterlogging and its response relationship with hourly rainfall intensity were discussed. The results show that urban waterlogging was strongly correlated with short-duration heavy precipitation in Tongliao City, which can provide a reference for the monitoring and early warning of urban waterlogging as well as flood control and drainage management.
