摘要
交通一体化在整个城镇化过程中始终起着至关重要的基础性作用,高速公路是交通一体化的重要组成部分,基于陇南市2014年─2016年的数据资料,构建城镇化与高速公路发展的评价指标体系和时间维度的耦合协调模型,运用熵值法进行指标赋权,测算出陇南市2014年─2016年城镇化与高速公路发展的综合水平与耦合协调度并进行分析。结果表明:城镇化的发展与高速公路的建设之间具有强力互补作用,决定性指标之间有密切的关联性;耦合协调度经历了3个阶段,发现高速公路几乎以2倍的速率向前增长,城镇化的增长速率不到1. 5倍,未来3 a存在耦合不平衡隐患。
Traffic integration plays a crucial role in the process of Urbanization,highway is an important part of traffic integration.Based on the data from 2014 to 2016 in Longnan,The dimensions of the evaluation index system and the model of time coordination of urbanization and the development of the highway,using the entropy method to determine the index weight,calculate the comprehensive level of urbanization in Longnan city from 2014 to 2016 with the development of the highway and the coupling coordination degree and analysis.The results show that the strong complementary effect between highway construction development and urbanization,there is close correlation between the decisive index;coupling coordination degree has experienced three stages,found the highway almost increased by a rate of two times forward,urbanization growth rate of less than 1.5 times,the next three years to unbalanced coupling risk.
