Chemical industry parks in China are considered high-risk areas because they present numerous risks that can damage the environment, such as pollution incidents. In order to identify the environmental risks and the principal risk factors in these areas, we have developed a simple physical model of a regional environmental risk field (ERF) using existing dispersal patterns and migration models. The regional ERF zoning was also conducted and a reference value for diagnostic methods was developed to determine risk-acceptable, risk-warning, and risk-mitigation zones, which can provide a risk source layout for chemical industry parks. In accordance with the environmental risk control requirements, this study focused on the three stages of control and management of environmental risk and established an environmental risk management system including risk source identification and assessment, environmental safety planning, early risk warning, emergency management, assessment of environmental effects, and environmental remediation of pollution accidents. By using this model, the environmental risks in Tianjin Binhai New Area, the largest chemical industry park in China, were assessed and the environmental risk zoning map was drawn, which suggested the existence of many unacceptable environmental risks in this area. Thus, relevant suggestions have been proposed from the perspective of the adjustment of risk source layout, intensified management of environmental risk control and so on.
中国的化工园区被认为是高风险区域,因为它们存在许多可能破坏环境的风险,如污染事件。为了识别这些地区的环境风险和主要风险因素,我们使用现有的扩散模式和迁移模型,开发了一种区域环境风险场(ERF)的简单物理模型。还进行了区域 ERF 分区,并制定了诊断方法的参考值,以确定风险可接受、风险预警和风险缓解区,为化工园区提供风险源布局。根据环境风险控制要求,本研究侧重于环境风险的控制和管理的三个阶段,并建立了包括风险源识别和评估、环境安全规划、早期风险预警、应急管理、环境影响评估和污染事故环境修复在内的环境风险管理系统。通过使用该模型,评估了中国最大的化工园区——天津滨海新区的环境风险,并绘制了环境风险分区图,表明该地区存在许多不可接受的环境风险。因此,从风险源布局调整、加强环境风险控制管理等角度提出了相关建议。
