长江三角洲城市群新型城镇化与城市交通协调发展研究

Research on the Coordinated Development of New Urbanization and Urban Transportation in Yangtze River Delta Urban Agglomeration

以长江三角洲城市群为研究对象构建多指标体系,以综合因子分析法和熵值法赋予指标权重,通过TOPSIS法和耦合协调度模型对各城市新型城镇化与城市交通进行综合评价,结合k-means聚类法对城市分类,以分级色彩图的形式呈现出研究结果。结果表明:(1)长江三角洲城市群内上海的新型城镇化发展水平最高,其次分别是浙江、江苏和安徽,都市圈内各城市新型城镇化发展水平普遍较高;(2)各城市交通发展状况与其规模和功能地位等密切相关;(3)不同城市新型城镇化与城市交通存在相互制约或相互促进的差异。因此,各城市加强新型城镇化与城市交通建设的同时,还应注重提高二者的适应水平。

Taking the Yangtze River Delta urban Agglomeration as the research object,a multi-index system is constructed in the paper,and factor analysis method and entropy value method are used to give weight to these indexes.The TOPSIS and the coupling coordination degree model are applied to comprehensively evaluate the new urbanization and urban traffic in each city.Finally,the K-means clustering method is used to classify each city and the research results are presented in the form of color map.The results show that:(1)In the Yangtze River Delta urban Agglomeration,Shanghai has the highest level of new-type urbanization development,followed by Zhejiang,Jiangsu and Anhui provinces.The cities in the metropolitan area generally have a higher level of new-type urbanization development.(2)The traffic development of each city is closely related to its scale and functional status.(3)There are differences between new-type urbanization and urban traffic in different cities,and they may restrict or promote each other.Therefore,while strengthening new-type urbanization and urban traffic construction,cities should also pay attention to improving their adaptation level.
