基于PSR模型的石化园区海洋环境影响后评估指标体系研究

我国将建成七大国家级石化产业园区,这些石化园区无一例外的位于沿海地区或海岛上,为此加强石化园区运营期海洋环境保护意义重大.环境影响后评估是运营期检验园区环境管理水平、查找园区环境问题的重要手段之一.目前,石化园区环境影响后评估主要以环境要素逐一分析法最为常见,而将石化园区作为一个整体从资源、环境、管理等角度综合评估的方法尚不多见.本研究在阐述我国海洋环境后评估和深入分析石化园区用海特点的基础上,结合PSR框架模型加以总结,提出了石化园区海洋环境影响后评估框架与指标体系,分为框架层、方案层和指标层,共25项考核指标,以期为今后沿海石化园区海洋环境管理研究提供思路.同时,本研究明确了各类评估指标赋值和权重等计算方案,并以大连某石化园区为案例进行了评估效果验证.

Research on the indicator framework in the post marine environmental impact assessment in petrochemical park based on PSR model

Seven National Petrochemical Industrial Parks will be built, which are located either in the coastal areas or islands. It is important to strengthen marine environment protection during the petrochemical park operational period. Post environmental impact assessment (PEIS) is one of the important means to check the environmental management level and find the environmental problems during the operational period. At present, one of the most common PEIS methods is environmental factor analysis. However, it is still rarely applied in the petrochemical park as a whole. The method is based on evaluating resource, environment and management. Based on the analysis of the marine environment in China and the analysis of the petrochemical park sea use, and combined the characteristic of PSR model, the evaluation indicator system of marine environmental impact is put forward. The system is divided into framework layer, solution layer and index layer, with a total of 25 assessment indicators. The system can provide ideas for the petrochemical park marine environmental management research in the future, At the same time, the evaluation scheme of various evaluation indicators such as assignment and weight is established. At last, a case study of a petrochemical park in Dalian was carried out to verify the effectiveness of the evaluation.
