四川省生态环境分区管控与规划环评水污染物排放控制量联动管理实践研究OA

The coordinated management of ecological-environmental zoning control and planning environmental impact assessment(EIA)is an important approach to optimizing industrial layout and promoting green development.In this study,the jointed practice of"dual-quantity"(i.e.,the permitted discharge limits under zoning control and the pollutant discharge control targets in planning EIA)in Sichuan Province was taken as an example,with existing issues systematically analyzed,such as mismatched regulatory scales,inflexible adjustment mechanisms,and imperfect supervision processes.Based on typical case studies,a hierarchical dynamic management mechanism was proposed:simplified linkage for areas with stably compliant water quality and in-depth linkage for non-compliant areas.Additionally,it is recommends that an information-based supervision platform should be established for dynamic monitoring and improving the in-process and post-event oversight system.The research findings provide practical references for refining ecological-environmental zoning control systems and deepening EIA reforms,offering significant guidance for constructing a comprehensive environmental management framework.
