摘要：以江苏沿海40家化工园区为例,综合考虑化工园区评价单元与环境风险区域性、系统性和行业性特征,构建了包括风险源、控制机制、风险受体3项一级指标、9项二级指标的环境风险分级综合模型,提出以指标贡献率作为优先管理策略的半定量筛选依据.结果表明,研究区域内共有江苏响水陈家港化工集中区、江苏连云港化工产业园区、如皋精细化学工业园等7个高风险园区,其风险产生与园区产业结构、园区地理布局紧密相关.根据指标贡献度将7个高风险化工园区划分为两类化工园区:一类是以受体敏感性为主控风险因素的化工园区;一类以风险源以及风险控制为主控因素的化工园区.针对这两类化工园区,分别从环境监管、提高清洁生产水平、化工企业数量总量控制、污水处理厂及配套管网建设等方面提出优先管理策略.

Abstract：Acomprehensive environment risk ranking model was established including 3 first-grade indicators (including risk source indicator, risk controlling indicator and risk receptor indicator) and 9 second-grade indicators. The characteristics of region, system and industry for environmental risks as well as features of industrial parks were simultaneously considered, and a semi-quantitative screening approach based on indicators’ contribution was applied to prior management strategy in a case study of 40 industrial parks in the coast area of Jiangsu Province. 7 chemical industrial parks (including Chenjiagang Chemical Industry Park of Xiangshui, Chemical Industry Park of Lianyungang, Rugao Fine Chemical Industry Park, etc.) were ranked higher in environmental risk assessment, which were closely related to their industrial structures and geographical distributions. The 7 high risk industrial parks were categorized into two groups by the characteristics of indicators’ contributions. One group was risk receptor dominated, and the other was risk sources and risk control dominated chemical industrial parks. Finally, different priority management strategies were proposed to these two groups.

近年来,我国因污染排放及环境事故所引起

-的环境风险呈上升趋势[12],与污染物总量逐渐

得到有效控制不同,环境风险涉及的污染物多、

介质复杂、受体广泛.随着经济社会的高速发展

和转轨阶段的来临这种风险将愈加突出[3].“防范

风险”已被纳入到国家环境保护“十二五”规划体

系之中[4].

环境风险管理依据空间尺度差异可划分为宏观、中观、微观3个层次,相对应的即是区域/流域风险管理、园区/镇/街风险管理、具体企业风风险管理3个层面[5].当前,对中微观层面的环 收稿日期：2010-10-10 基金项目：国家自然科学基金资助项目(40976021,40901081);引进海外高层次文教专家重点支持计划项目;江苏省太湖治理科研课题(TH2010301) * 责任作者, 教授, xdzhu@
