- 摘要:
- 为揭示城镇化与资源环境承载力协调发展的内在规律,对城市群高质量发展提供支持,以滇中城市群为例,运用耦合协调度模型及空间自相关等分析方法,对2000年、2010年、2018年城镇化与资源环境承载力耦合协调空间演变特征进行了分析。结果表明:(1)2000—2018年城镇化水平指数均值由0.149升至0.359,在空间上由“单核心”发展转变为“一主四副”的发展格局。资源环境承载力水平先下降后上升,各年均值为0.406,0.402,0.442,其空间分布的内部差异较大。(2)研究区耦合协调度均值由0.482上升至0.621,在空间上呈“西北低、东南高”的分布格局; 其Moran's I大于0.42,表现出较强的空间集聚性。(3)研究期内,耦合协调度与城镇化水平、资源环境承载力的空间相关程度较强,但呈现下降趋势。城镇化在协调发展中占主导作用。城镇化与资源环境承载力存在空间负相关关系,二者双变量Moran's I由-0.069降至-0.211,空间差异增大。通过有针对性的提高在空间关系中较弱的一方,进而实现滇中城市群城镇化与资源环境承载力的协调发展。
- Abstract:
- In order to reveal the pattern of coordinated development of urbanization and resources and environment carrying capacity and provide support to the high-quality development of urban agglomerations, taking the central Yunnan urban agglomeration as an example, we used the coupled coordination degree model and spatial autocorrelation and other analysis methods to analyze the spatial evolution characteristics of coupled coordination between urbanization and resources and environmental carrying capacity in 2000, 2010 and 2018. The results show that:(1)the average value of urbanization level index increased from 0.149 in 2000 to 0.359 in 2018, and the spatial development pattern changed from a single-core development in Kunming's jurisdiction to a development pattern of one main center and four secondary centers; the average value of resources and environment carrying capacity level decreased and then increased, and the average value of each year was 0.406, 0.402 and 0.442, and the internal differences of its spatial distribution were large;(2)the mean value of coupling coordination degree in the study area increased from 0.482 to 0.621, with a spatial distribution pattern of low in the northwest and high in the southeast; its Moran's I was greater than 0.42, showing strong spatial agglomeration;(3)during the study period, the spatial correlation between the coupling coordination degree, urbanization level, and resource and environmental carrying capacity was strong, but showed a decreasing trend; urbanization played the dominant role in the coordinated development; there was a negative spatial correlation between urbanization and resources and environment carrying capacity, and the bivariate Moran's I of the two decreased from -0.069 to -0.211, the spatial difference increased. By targeting to improve the weaker side in the spatial relationship, the coordinated development of urbanization and resources and environmental carrying capacity of the central Yunnan urban agglomeration can be realized.
