【摘要】：不同形式的可达性指标所揭示的交通基础设施可达性特征具有差异性,客观地将不同指标进行综合以全面掌握可达性效应,对于科学评估交通基础设施新建的效果具有重要意义。文章综合运用GIS网络分析、Super-DEA、空间变差函数等多种研究方法,从空间相互作用成本和效益出发,选取4种常用可达性指标和本文构建的综合可达性指数分析了厦深高铁开通引起的粤闽沿线地区可达性变化与空间分异特征。结果表明:厦深高铁开通在整体上显著降低广东省城镇出行时间的同时,扩大了福建省城镇空间相互作用潜力与吸引范围;综合可达性指数形成了以珠三角中东部地区为核心,向外围逐渐递减的空间分异特征,广东省综合可达性水平明显优于福建省;厦深高铁的开通促进了区域可达性公平性水平的提升,广东清远、河源、潮州以及韶关部分地区、福建的龙岩、漳州等地综合可达性指数变化有利于可达性空间公平性水平的提高;粤西和闽北地区、核心地域的珠三角东部和中部地区综合可达性指数变化则引起了可达性空间差异的增加。
[Abstract]:The accessibility characteristics of traffic infrastructure revealed by different forms of accessibility indicators are different, so the different indicators can be synthesized objectively in order to fully grasp the accessibility effect. It is of great significance for scientific evaluation of the effect of new traffic infrastructure. In this paper, we use GIS network to analyze Super-DEA-spatial variation function and other research methods, and proceed from the cost and benefit of spatial interaction. Four commonly used reachability indexes and the comprehensive accessibility index constructed in this paper are selected to analyze the characteristics of accessibility and spatial differentiation in Guangdong and Fujian areas caused by the opening of Xiamen and Shenzhen high-speed railways. The results show that, while reducing the travel time of cities and towns in Guangdong Province, the urban spatial interaction potential and attraction range of Fujian Province have been enlarged, and the comprehensive accessibility index has taken the central and eastern areas of the Pearl River Delta as the core. The characteristics of spatial differentiation decreasing gradually to the periphery, the comprehensive accessibility level of Guangdong Province is obviously superior to that of Fujian Province; the opening of Xiamen and Shenzhen high-speed railways has promoted the improvement of regional accessibility fairness level. Qingyuan, Heyuan, Chaozhou and some parts of Shaoguan in Guangdong Province, The change of comprehensive accessibility index in Longyan, Zhangzhou and other places in Fujian is beneficial to the improvement of spatial equity level of accessibility. The variation of the comprehensive accessibility index in the eastern and central areas of the Pearl River Delta leads to the increase of the spatial difference of accessibility.
