【摘要】 以镇江市征润州水源地为例,针对目前存在的工业源众多导致的事故模拟工作量大,码头源难以进行事故模拟等问题,提出基于常规风险影响的水源地周边风险源风险监控等级判定方法。从风险源与水源地沿岸线方向距离、垂直岸线方向距离和上下游关系3方面提出反映风险源相对于水源地位置敏感性的位置敏感指数的计算方法,再以风险源位置敏感性结合风险源风险,确定风险源对水源地的常规风险影响,继而判定水源地周边风险源的风险监控等级。结果表明,征润州水源地周边优先重点监控风险源有4个,主要集中在水源地上游丹徒经济开发区内,水源地下游及对岸12个风险源为低频监控等级,其他24个风险源为优先监控和一般监控等级。更多还原

【Abstract】 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.更多还原
