“双碳”目标下资源型城市韧性发展

    Resilient development of resource-based cities under the dual carbon goals

    • 摘要: 依赖高碳发展模式的资源型城市在绿色低碳转型、实现“双碳”目标过程面临诸多风险。通过提升城市韧性将减排压力转化为城市内部减排动力,更好处理“双碳”目标与高质量发展间的协同关系,是最终实现可持续发展的关键。将城市韧性作为资源型城市应对“双碳”目标的实际响应,通过构建资源型城市韧性评估体系,在量化评估2010—2019年中国30个资源型城市韧性水平的差异基础上,比较了碳排放变化与资源型城市韧性二者间变化关系,主要结果如下:①2010—2019年中国30个资源型城市韧性水平均有提升,但差距在不断扩大;在空间演变方面,资源型城市韧性水平整体呈现东部高、西部低的特征,2013年之后的表现更明显;从城市内部韧性系统看,经济韧性与生态韧性的协调度较高,为“双碳”目标下资源型城市韧性提升的良好基础;②资源型城市韧性与碳排放的比较研究表明,二者绝对值变化趋势均呈上升状态,增长速率呈现先下降、后上升的趋势,虽然尚未实现“碳达峰”,但城市韧性的增加速率远高于碳排放增速,城市韧性有望成为应对气候变化、实现“双碳”目标的重要手段。基于上述内容,提出构建“双碳”目标下资源型城市韧性评估体系与保障政策体系建设相关建议。

       

      Abstract: Resource−based cities that rely on high−carbon development models face many risks in the process of green and low−carbon transformation and achieving the dual carbon goals. Transforming the pressure of emission reduction into the driving force for emission reduction within the city by improving urban resilience, and better handling the synergistic relationship between the dual carbon goals and high−quality development, is the key to the ultimate realization of sustainable development. This study regards urban resilience as the actual response of resource−based cities to the dual carbon goals. By constructing a resource−based city resilience assessment system, it quantitatively evaluates the differences in resilience levels of 30 resource−based cities in China from 2010 to 2019, and compares changes in carbon emissions with resource−based cities. The main results of the relationship between urban resilience are as follows: ①In terms of time evolution, the resilience of 30 resource−based cities increased over time, and the gap in resilience levels between cities continued to expand; in terms of spatial evolution, the resilience of resource−based cities show the characteristics of high in the east and low in the west, which is more obvious since 2013; in terms of the coordinated development of urban resilience, the degree of coordination between economic and ecological resilience is high, which is the resilience of resource−based cities under the dual carbon goals. ②Comparing the urban resilience with the carbon emissions of resource−based cities, the trend of their absolute values is rising, and the growth rate is decreasing first and then rising. Although the resource−based cities have not reached the peak, the growth rate of urban resilience is much higher than the growth rate of carbon emissions. Urban resilience is expected to be an important means of tackling climate change and achieving the dual carbon goals. Based on the above content, suggestions on building a resource−based urban resilience assessment system and safeguarding policy system with the dual carbon goals are put forward.
