最小生态安全距离在“多规合一”中的地位与作用

摘要

Multiple planning integration is an inevitable trend of the city planning and the urban management in the future. The minimum distance for ecological safety (MDES) offers a new way of thinking and technical guidance to realize the multiple planning integration, which combines multi­factors like a city’s natural background, ecological protection, safety baseline, resource carrying capacity, environmental capacity, and social economics to devise specific ecological safety standards for managing different environmental spaces. The minimum distance for ecological safety is a new concept that is brought forward to safeguard a city’s basic ecological safety baseline. The minimum distance for ecological safety not only serves as a basis for scientifically defining urban layout and enhancing the quality of urban development and space management, but also carries significant meaning to establish and carry out urban planning.%“多规合一”是未来规划编制与管理城市的必然发展趋势。最小生态安全距离不仅是探索“多规合一”的重要技术工具，也是“多规合一”中空间管控的重要内容。最小生态安全距离以资源环境承载力为基础核心，是城市开发不能逾越的距离。划定最小生态安全距离是为了满足城市生态系统良性循环、生态系统服务功能正常运转以及环境容量不超载，城市间或城市功能单元间经济社会活动空间间隔的最小距离。利用最小生态安全距离划定出的基本规避空间，可以让环规、城规和土规实现统一的空间管控的最终目标。依靠最小生态安全距离，能够科学地划定城市布局，提升城镇化发展质量和空间管控质量，更好地实现城市规划的编制与管理。
