摘要
为了预防由于工业企业危险物质泄漏引发的环境突发事故,保护流域水环境安全.本研究选用基于Seveso Ⅲ指令模型的方法进行流域环境风险评价研究,并对模型进行适应性改进,选择工业企业分布较为密集的泉州晋江流域进行了示范研究.利用高程、企业分布、危险物质储存量等数据,得到企业内在风险;叠加区域易受损性后得到子区域的环境风险.结果表明,南安市是晋江流域环境风险最高的子区域,风险值高达108,安溪县和泉州市区风险水平居中,晋江市为低度危险子区域.在此基础上,根据评价结果提出了具有针对性的流域环境风险控制建议.
In order to prevent major industrial accidents involving dangerous substances and help protect the water environment security, the model in context of Seveso Ⅲ Directive was chosen for the watershed environmental risk assessment. There were a number of factories widely distributed in Jinjiang watershed. Here a case study was applied in Jinjiang watershed, Quanzhou, after an improvement of this model. The leakage risk was assessed with the digital elevation data, the distribution of industries and the storage of dangerous substances. The regional industrial environment risk was further assessed together with the regional vulnerability. According to the results, Nan＇an had the highest risk with a value of 108, while Anxi and Quanzhou city had a medium level. Jinjiang City was with the lowest value at risk. Based on the above, some targeted suggestions were proposed for environmental risk control in Jinjiang watershed.
