摘要
选取加权平均旅行时间、可达性系数和经济联系强度等指标,分析有无高速铁路格局下安徽省16个地级市可达性及城市间经济联系强度的变化。研究发现:高速铁路极大地提高了交通可达性水平,各城市加权平均旅行时间平均缩减40.97%;城市间相对可达性差距增大,两极分化加剧;合肥、芜湖、蚌埠3个中心城市的辐射能力增强,3小时交通圈中,合肥实现省内城市全部连接;各城市经济联系总量均值增至8.76倍,大于300经济度的联系主要沿宁安客运专线、合福高铁、京沪高铁和商合杭客运专线(北段)分布,其中宁安客运专线轴线效应明显。经济联系强度的变化与可达性水平变动表现出一定程度的耦合性。
Taking Anhui province as the research area and choosing indicators such as weighted average traveling time,accessibility coefficient and economic linkage intensity,this paper analyzes the change of accessibility and the economic linkage among 16 cities before and after the construction of HSR through spatial analysis tools in GIS.The results show:After the construction of HSR,the weighted average travel time reduced by 40.97%on average,but the overall pattern did not change much;the gap of relative accessibility between cities increased,and the polarization is more serious;the radiation capacity of Hefei,Wuhu and Bengbu was significantly enhanced,and all cities in the province was in Hefei's three-hour reached high-speed railway transportation circle;the average value of total economic linkages among 16 cities increased to 8.76 times.Generally,a peripheral expansion mode centering on Hefei was presented.The change of city's economic linkage intensity and accessibility level showed a certain degree of spatial coupling.
