“生态底线”理念在山地城市中的辩证运用——对攀枝花市“集约生态控制线”的探索

Dialectical Application of “Ecological Bottom Line” in Mountainous Cities:Exploration on “Intensive Ecological Control Line” in Panzhihua City

在土地资源高约束条件下，如何协调生态保护与城市发展的矛盾是山地城市共同面对的问题。文章从生态底线与生态红线的辩证关系入手，通过辨析二者在管控内容和执行力度上的差异，将生态红线与多维空间、景观格局、城市结构及生态价值相结合，提出适应山地城市的“集约生态控制线”理念，其目的是强调保护与利用的辩证关系，实质是在生态保护的基础上，优化城市山水结构，实现非红线生态区用地的外部增值效益。通过“集约生态控制线”，加强城市建设功能用地与生态环境要素之间的积极互动，让自然生态环境成为体现城市生态软实力的新的经济增长点，引导城市步入良性生态循环的轨道。

Greatly limited by land resources, how to coordinate the contradiction between ecological protection and urban development becomes a common issue faced by mountainous cities. Starting from the dialectical relationship between the ecological bottom line and the ecological red line, the paper analyzes the differences between the two types of ecological lines in terms of control content and execution force. Then the paper combines the ecological red line with the multi-dimensional space, landscape pattern, urban structure, and ecological value, and puts forward the concept of ＂intensive ecological control line＂. The purpose is to emphasize the dialectical relationship between conservation and utilization in the process of delineating the ecological bottom line, and the essence is to achieve the external value-added benefits of the non-red line ecological area. Through the application of the ＂ intensive ecological control line＂, the positive interaction between urban construction land and ecological environment elements can be enhanced, and the natural ecological environment can become the new economic growth point of urban ecological soft power, so as to guide the urban development towards a benign ecological recycle.
