近20年黄河流域城乡耦合协调的演化特征及影响因素

目的]探究黄河流域城乡耦合协调演化特征及影响因素，对于促进流域内城乡融合发展具有重要的指示作用。方法]基于城乡耦合关系，构建评价指标体系，采用熵权TOPSIS法、耦合协调度和障碍度模型，从省域尺度测算2000—2019年黄河流域八省(区)城市、乡村综合发展水平，分析城乡耦合协调的演化特征及影响因素。结果]研究期内黄河流域城市、乡村综合发展水平不断上升，分别由0.34,0.35增至0.43,0.4,均呈中下游地区高于上游地区的空间格局。时间分异上，黄河流域城乡耦合协调度整体呈由“基本失调”向“基本协调”发展的上升特征，八省(区)平均水平由0.5上升至0.59。空间分布上，黄河流域城乡耦合协调度呈现从上游到下游逐级递增的阶梯式格局，空间异质性突出。从城市系统阻碍城乡耦合协调发展的主要因素由城市人口密度、城镇常住人口转变为城市人均第三产业产值、城市人均GDP,从乡村系统阻碍城乡耦合协调发展的主要因素为经济领域的乡村人均可支配收入、乡村人均农林牧渔业产值，整体上黄河流域城乡耦合协调程度主要受经济发展水平影响。城乡政策和区域规划对城乡耦合起促进作用，资源禀赋对城乡耦合格局产生固化作用。结...

Evolutionary Characteristics and Influencing Factors of Urban-Rural Coupling Coordination in Yellow River Basin in Recent 20 Years

Objective]Exploring the characteristics and influencing factors of the coordinated evolution of urban-rural coupling in the Yellow River Basin plays an important role in promoting the integration of urban and rural development in the Yellow River Basin. Methods] Based on the urban-rural coupling relationship, an evaluation index system was constructed. The comprehensive urban and rural development levels of the eight provinces(regions)in the Yellow River Basin from 2000 to 2019 were calculated based on the provincial scale, and the evolution characteristics and influencing factors of urban-rural coupling coordination were analyzed by using the entropy weight TOPSIS method, the coupling coordination degree and the obstacle degree model. Results] During the study period, the comprehensive development levels of cities and villages in the Yellow River Basin continued to rise, from 0.34 and 0.35 to 0.43 and 0.4, showing a spatial pattern in which the middle and lower reaches were higher than the upper reaches. In terms of time differentiation, the overall degree of urban-rural coupling coordination in the Yellow River Basin showed an upward trend from basic imbalance to basic coordination, and the average levels of the eight provinces(regions)increased from 0.5 to 0.59. In terms of spatial distribution, the urban-rural coupling coordination degree in the Yellow River Basin presented a step-by-step pattern from upstream to downstream, with prominent spatial heterogeneity. The main factors hindering the coordinated development of urban-rural coupling from the urban system had changed from urban population density and urban permanent population to urban per capita tertiary industry output value and urban per capita GDP. Rural per capita disposable income, rural per capita output value of agriculture, forestry, animal husbandry and fishery, the degree of coupling and coordination between urban and rural areas in the Yellow River Basin were mainly affected by the level of economic development. Urban-rural policies and regional planning promoted the urban-rural coupling, and resource endowment had a solidifying effect on the urban-rural coupling pattern. Conclusion]The principles of ‘developing first, paying equal attention to protection' and ‘improving quality and efficiency, and focusing on development' should be adhered by category, and the coordinated development level of urban and rural areas in different provinces in the Yellow River Basin should be improved.
