规划环评中区域生态风险评价框架研究

Research on the Framework of Regional Ecological Risk Assessment in Planning Environmental Impact Assessment

  • 摘要: 随着国家重点区域、重点产业和行业发展战略的深入推进,由人类规划开发所导致的生态风险加剧,部分地区正面临环境污染、生境退化、生物多样性减少等负面生态影响,使得在规划实施前开展生态风险评价变得尤为迫切。通过回顾我国规划环评中区域生态风险评价的发展历程,在总结国内外主流框架成果、经验及存在问题的基础上,提出了由风险问题形成、“压力-状态-响应”分析、区域风险综合评价、风险管理四部分组成的适合我国国情的生态风险评价框架,该框架加强了管理者与利益相关者的输入、归纳了区域风险源、完善了综合评价内容,以期对生态风险评价在我国区域规划环评中的应用起推动作用。

     

    Abstract: With the further development of national strategy on key areas, industries and sectors, ecological risk caused by human planning and exploitation is increasing. Some areas are now facing with negative ecological impacts including environmental pollution, habitat degradation and biodiversity loss, which makes ecological risk assessment (ERA) before the implementation of plans become more urgent. The history of regional ecological risk assessment (RERA) was reviewed, the results, experiences and problems of its mainstream framework at home and abroad summarized, and a framework of RERA suitable for China consisting of four parts, i.e. Risk Problem Formulation, Pressure-State-Response Analysis, and Comprehensive Assessment and Risk Management, presented. In the framework, the input of risk managers and interested parties was enhanced, the regional risk sources summed up, and the contents of comprehensive assessment improved. The framework could promote the application of RERA in China’s planning environmental impact assessment.
