|Taking Zhenjiang Zhengrunzhou Water Source as an example, considering the heavy workload of simulation of pollution accidents caused by the large number of the existing industrial sources and accident simulation of the wharf sources being unavailable, we bring forward a method for judging risk monitoring level of risk sources around water source based on conventional risk impact. A calculation method for the location sensitivity index reflecting the sensitivity of the risk source to the location of the water source is proposed from the distance between the risk source, the water source along the coast line and the vertical shoreline, and the upstream and downstream relationship. The risk source location sensitivity combined with the risk source’s risk has been used to determine the routine risk impact of the risk source on the water source, then determine the risk monitoring level of the risk source around the water source. The result shows that there are 4 priority monitoring risk sources around the water source of Zhengrunzhou, they mainly concentrated in the Dantu Economic Development Zone in the upper reaches of the water source. The 12 risk sources of downstream and on the opposite side of the water source are low-frequency monitoring levels. The other 24 risk sources are priority monitoring and general monitoring levels.
