Abstract:chemical industrial park and implement risk management more effectively,the calculation methods ofrisk field strength and receptor vulnerability were optimized based on the technical idea ofenvironmental risk field evaluation method. A set of cumulative atmospheric environmental risk assess⁃ment method was established based on the assessment unit of 100 m× 100 m. Taking a chemicalindustry park as an example,the atmospheric environmental risk in this area was divided into four lev⁃els,and the results were verified by the environmental protection report data. The results showed thatthe atmospheric environmental risk of the park evaluated by the established method was consistent withthe actual situation. Thus the method could provide reference for environmental risk prevention and con⁃trol of the park. Close-
