“三线一单”生态环境分区管控的技术方法体系

Theories and Methods of the Ecological and Environmental Zoning MangementSystem of “Three Lines One Permit”

“生态保护红线、环境质量底线、资源利用上线和生态环境准入清单”(即“三线一单”)生态环境分区管控体系是落实生态文明建设、推动经济高质量发展和生态环境高水平保护的重要抓手,是新时期改革发展背景下生态环境管理制度的新突破和国土空间管控的新探索,构建了“问题-目标-单元-清单”系统性管控体系,具有完整性、一致性、科学性等特征。本文在系统梳理“三线一单”生态环境分区管控总体框架和关键方法技术的基础上,明确了“三线一单”生态环境管控分区划定各环节的主要任务及技术要点,建议在具体工作中注意把握以下几方面,即生态功能不降低、环境承载促减排、资源利用保协同、管控等级不降低。

The former MEP(Ministry of Ecology and Environment)promoted an integrated environmental management policy called“Three Lines One Permit”in 2017,to implement the construction of ecological civilization,sustainable development and high level environmental protection.“Three Lines One Permit”is combined with a red line for ecological conservation,a bottom line for environmental quality,an upper limit line for resource using and a list of environmental permits for human activities.The ecological and environmental partitioning system is a new breakthrough of ecological environment management and new exploration of land space control under the background of reform in the new era of China.The“Three Lines One Permit”system is consisted of“Questions-Objectives-Partitions-Lists”,with the characteristics of integrity,consistency and scientific nature.Based on the overall framework and methods of“Three Lines One Permit”,the main tasks and technical points of each link of the ecological and environmental partitioning system were presented.We suggested to ensure that the systematic requirements of ecological function,environmental capacity and emission reduction,resource utilization coordinated,and the environmental control level not reduced.
