甘肃省综合交通网络与人口、经济耦合分析

Analysis of Coupling Degree between Comprehensive Traffic Network and Population-economic System in Gansu Province

构建交通运输系统与人口、经济系统评价指标体系,采用熵权耦合协调度模型和缓冲区分析方法,对甘肃省2000~2010年交通与人口、经济协调度的时空差异进行分析。结果表明:甘肃省交通运输系统与人口经济系统综合发展水平以及两系统的耦合协调度均在逐年提高,协调等级由2000年的中度失调提升至2010年的初级协调,但协调度增长速度缓慢;人口分布、经济发展与交通布局空间上密切相关。根据空间缓冲区分析结果,将甘肃省14个市州分类划归为高度相关、中度相关及一般相关等三种类型。最后针对系统发展存在的问题,提出了相应建议。

The transportation and population-economy evaluation index systems were set up, then improved entropy weight method was determined. The assessment model was applied to analysis temporal and spatial change of traffic and population-economic coordination degree in Gansu province from 2000 to 2010. The results show that the developing levels and coupling coordination degree of traffic system and population-economic system have increased. The coupled coordination level has developed from moderate disorder in 2000 to primary coordination in 2010, but the coordination degree of growth speed has been slow. Population distribution, economic development and traffic layout are closely related to spatial layout. According to the results of buffer analysis, the population, economic and traffic tightness was divided into highly correlated, moderately correlated and generally correlated three types. 14 cities and prefectures in Gansu Province were classified and analyzed and corresponding recommendations were proposed based on the problems in the development for the systems.
