厘清“三线一单”制度与技术逻辑支撑国家生态环境治理体系现代化

Study on the Logic of the“Three Lines and One List”to Support the Modernization of National Ecological Environment Governance

“三线一单”编制工作持续推进,长江经济带11省(市)和青海省等大部分省份“三线一单”编制成果已经发布,其余19省(区、市)及新疆生产建设兵团“三线一单”工作也进入成果审核阶段,预期2020年底发布完成。本文在成果表达和地方实践的基础上梳理了“三线一单”的作用和功能定位,认为“三线一单”实现了生态环境空间管控落地,是适应“放管服”改革背景下发挥源头预防作用的重要举措。“三线一单”编制工作凝结了源头预防生态环境风险的空间管控思路,技术逻辑从问题和目标导向出发,形成区域开发的“框子”和“规矩”,确保生态系统结构完整性、功能健康性和过程持续性。基于技术逻辑和已发布成果的案例分析可知,“三线一单”实施能够提升国土空间规划、区域国民经济发展规划和地方立法等领域的绿色化发展水平,支撑生态环境体系和治理能力现代化。

The works of“Three Lines and One List”(ecological conservation redlines,environmental quality bottom lines,resources utilization ceilings,access list based on the baseline of ecology,environment and resources)have entered an important stage to issue the results in Qinghai Province and the 11 provinces and cities of the Yangtze River Economic Belt,and to audit the achievements in other 19 provinces,which is expected to be released by the end of 2020.On the basis of achievement expression and local practice,this paper summarizes the role and functional position of the“Three Lines and One List”,which is an important measure to adapt to the reform of“decentralization,management and service”and to play the role of prevention at the source.The works of“Three Lines and One List”condenses the spatial management and control idea of source prevention of ecological environment risk;its technical logic is based on the problem and goal orientation to ensure the structural integrity,functional health and process continuity of ecosystem.Based on the technical logic and case analysis of the published results,the implementation of“Three Lines and One List”can improve the level of green development in areas such as land and space planning,regional national economic development planning and local legislation,and support the modernization of the ecological environment system and governance capabilities.
