With the rapid economic and social development and accelerated urbanization, the negative ecological impact of major river basins worldwide has been deepening, which is gradually threatening the sustainable development of cities. This study establishes the model of the coupling coordination relationship between social economy and resources environment of nine central cities in the Yellow River Basin. Based on the evaluation index system of social economy and resource environment, we quantitatively measure the coupling coordination degree and spatiotemporal pattern of the nine central cities from 2010 to 2017. The obstacle factors of coupling coordination were then diagnosed based on the obstacle degree model. The results showed that (1) the social economy and resources environment development indices of the nine central cities in the Yellow River Basin, as well as the coupling coordination of each central city, showed an overall upward trend from 2010 to 2017. (2) Most of the central cities in the Yellow River Basin were in the coordinated coupling stage, among which Xining and Lanzhou have the highest coupling degree. (3) The obstacle factors affecting the harmonious development coupling coordination of the nine central cities were natural growth rate of population, proportion of tertiary industry in GDP and per capita investment in fixed assets in social economy system, and per capita green area of parks, per capita total amount of water resources, and per capita industrial SO₂ emissions in resources environment system. It is necessary to adopt different strategies for different cities to promote the coupling coordination development of urban social economy and resources environment in the Yellow River Basin.

黄河流域中心城市社会经济与资源环境时空耦合协调分析。

随着经济社会的快速发展和城市化进程的加快，世界主要流域的负面生态影响日益加深，逐渐威胁到城市的可持续发展。本研究建立了黄河流域九个中心城市社会经济与资源环境耦合协调关系的模型。基于社会经济和资源环境评价指标体系，定量测量了9个中心城市在2010年至2017年的耦合协调度和时空格局，然后基于障碍度模型对耦合协调的障碍因素进行了诊断。结果表明：（1）黄河流域9个中心城市的社会经济和资源环境发展指数以及每个中心城市的耦合协调度从2010年到2017年总体呈上升趋势。（2）黄河流域大多数中心城市处于协调耦合阶段，其中西宁和兰州耦合程度最高。（3）九个中心城市协调发展协调协调的障碍因素包括人口自然增长率，第三产业在国内生产总值中的比重和社会经济体系中人均固定资产投资，公园人均绿地面积，人均水资源总量和人均工业SO 从2010年到2017年总体呈上升趋势。（2）黄河流域大多数中心城市处于协同耦合阶段，其中西宁和兰州耦合度最高。（3）九个中心城市协调发展协调协调的障碍因素包括人口自然增长率，第三产业在国内生产总值中的比重和社会经济体系中人均固定资产投资，公园人均绿地面积，人均水资源总量和人均工业SO 从2010年到2017年总体呈上升趋势。（2）黄河流域大多数中心城市处于协同耦合阶段，其中西宁和兰州耦合度最高。（3）九个中心城市协调发展协调协调的障碍因素包括人口自然增长率，第三产业在国内生产总值中的比重和社会经济体系中人均固定资产投资，公园人均绿地面积，人均水资源总量和人均工业SO₂资源环境系统中的排放。有必要针对不同城市采取不同的策略，以促进黄河流域城市社会经济与资源环境的协调协调发展。
