工业园区环境风险源识别与分级研究

以多年来中国各行业突发环境事故统计数据为基础,选取了对于企业突发环境事件有重大影响的7个因子以及17个指标,采用指标因子分析法对其进行定量,应用层次分析法确定各因子的权重,从而确定企业环境风险水平值。基于"危险物质水平—企业环境风险水平—周边环境受体状况"体系,构建了环境风险源分级矩阵,形成了包括"环境风险源初筛","环境风险源分级"的两步工业园区环境风险源识别与分级方法。该方法提出的工业园区环境风险源识别与分级体系具有科学性和可行性,能为工业园区环境风险管理提供依据。

Identification and Classification Methods for Environmental Risk Sources of Industrial Park

Based on the statistical analysis of various paroxysmal environment events, the causes and the characteristics of the event was reflected by7 factors and 17 indexes, which was quantified by factor analysis. Then, analytic hierarchy process was used to confirm the weight of the factors, which was used to present risk level of an industry. Additionally, according to the system of ＂hazardous substance amount-enterprise environment risk-environmental receptor condition＂ an environmental risk classification ma- trix was constructed and a method including ＂environmental risk sources identification＂ and ＂risk source classification＂ was estab- lished. It shows the environmental risk identification and classification system is reasonable and feasible and it will benefit the envi- ronmental risk management of industrial park.
