摘　　要：以北方某沿海城市为例,通过收集资料、划分子区域、识别环境风险源及环境风险受体和调查区域突发环境事件应急能力及防治措施等,采用区域环境风险指数计算法与网格化环境风险分析法计算案例区域环境风险等级,对比分析2种方法区域环境风险评估结果。结果表明,案例区域水环境风险、大气环境风险和综合环境风险2种方法计算结果差异较大。指数法适用区域综合环境风险等级判断,网格法适用小尺度区域水、大气环境风险等级精确计算。Take a coastal city in the north,through data collection,subregion division,identification of environmental risk source and environmental risk receptors,investigation of regional emergency response capacity and prevention measures,the regional environmental risk level of the case was calculated by using the regional environmental risk index calculation method and the grid environmental risk analysis method,the regional environmental risk assessment results of the two methods were compared and analyzed.The results show that there is a great difference in the calculation results between the two methods of regional water environment risk,atmospheric environment risk and comprehensive environmental risk.It shows that the index method is applicable to regional comprehensive environmental risk level judgment,the grid method is suitable for the accurate calculation of the risk level of water and atmosphere environment in small scale area.
