山地旅游型城市城镇开发边界划定思路探索——以九寨沟县为例

Research on the Method of Demarcating the Urban Development Boundary of Mountain Tourism City:Taking Jiuzhaigou County as an Example

科学划定城镇开发边界是各级国土空间规划编制工作的重要内容之一。城镇开发边界作为城镇开发建设的核心管控界线,在城镇发展过程中发挥着管控约束和发展引导的双重作用。当前我国城镇开发边界划定研究普遍将关注重点聚焦于大中型平原城市,缺乏对于用地离散程度较高的山地旅游型城市的探讨,以及与建设用地指标空间配置的衔接研究。文章结合四川省阿坝藏族羌族自治州九寨沟县具体实践,探讨如何在"双评价"结论基础上,从全域旅游的角度分析筛选出适宜优先发展的新增建设用地,并通过评估乡镇发展潜能明确分配标准,提出山地旅游型城市城镇开发边界的划定方法,即通过构建"七步法"的技术框架,形成自上而下的城镇开发边界划定思路,对于优化山地旅游城市国土空间开发利用保护格局,促进城市绿色高质量发展起到了积极作用。

The scientific demarcation of urban development boundary is the main content for the national territory spatial planning,as the core control boundary of urban development,it plays a dual role of control and guidance in the process of urban development.At present,the research on the urban development boundary generally focuses on large and medium-sized plain cities,and lacks the discussion on mountain tourism cities with high degree of land dispersion and the connection with the regional allocation of construction land quotas.According to the practice of Jiuzhaigou County,Aba Tibetan and Qiang Autonomous Prefecture,Sichuan Province,this article discusses how to analyze the more suitable newly-added construction land from regional tourism perspective on the basis of double evaluation,and define the allocation criterion by evaluating the development potential of towns,and finally forms the method of demarcating the urban development boundary by building the technical framework of the seven-step method,which plays a positive role in optimizing the landscape pattern and promoting the green development of cities.
