资源型城市转型视角下的城镇开发边界研究——以铜川市为例

Research on the Urban Development Boundary from the Perspective of Resource——based City Transition: A Case Study of Tongchuan

随着生态文明建设的稳步推进和机构改革方案的落实,建立空间规划编制体系与划定城镇开发边界将成为限制城镇无序扩张的重要政策工具。以铜川市城镇开发边界划定为例,从资源型城市转型的视角提出城镇开发边界划定方法和策略,以期为西部地区及资源型城市划定城镇开发边界提供借鉴。针对资源型城市的特征,提出以下策略:(1)从城市转型和产业转型两大视角,提出资源型城市转型发展的生态、服务、交通、产业4大导向原则;(2)基于西部城市环境脆弱和资源型城市特点,在生态敏感性分析的基础上对城镇建设用地进行增长模拟,并对比在蔓延趋势下城镇建设用地增长模拟的差异及问题;(3)基于多规融合统筹全域空间的各种控制线,并针对资源型城市独立工矿区的开发边界提出相应对策。

With the continuous advancement of ecological civilization and the implementation of institutional reform programs, the establishment of a spatial planning system and the delineation of urban development boundaries will become important policy tools for restricting urban dislocation. Taking the delineation of the urban development boundary of Tongchuan City as an example, this paper proposes methods and strategies for delineating the urban development boundaries from the perspective of the transformation of resource-based cities, hoping to provide reference for the demarcation of urban development boundaries in the western regions and resource-based cities. According to the characteristics of resource-based cities, this paper proposes the following strategies. Firstly, from the perspectives of urban transformation and industrial transformation, four guiding principles for resource-based cities in ecology, services, transportation, and industry are proposed. Secondly, considering the fragile environment of western cities and the characteristics of resource-based cities, the urban construction space is simulated by growth based on the analysis of ecological susceptibility. The differences and problems in the simulation of urban construction land growth under the trend of spread are contrasted. Thirdly, various types of spatial control lines have been considered into the delineation of urban development boundaries. Some corresponding countermeasures for the development boundaries of independent industrial and mining areas in resource-based cities have been put forward as well.
