abstract="In order to analyze leakage and diffusion risk of hazardous chemicals during transportation, with influence of multiple factors taken into consideration, including uncertain wind condition, position of diffusion source and surrounding social environment, location of diffusion source was determined by scenario hypothesis. Then, population density distribution was characterized based on building distribution and population information, and possibility of wind condition was quantified by wind direction map. Finally, a construction method of risk potential map of toxic gas diffusion was proposed for comprehensive evaluation of possible influence area, and a case of liquid chlorine leakage and diffusion was analyzed by using scenario hypothesis. The results show that possible influence range of toxic gas diffusion can be more comprehensively evaluated with uncertainty of wind direction being considered. And regional population density can be quantitatively characterized by utilizing information of building distribution and number of people it can accommodate. © 2020 China Safety Science Journal<p /><p>Language: zh</p>",
