京津冀城市群城际高速铁路建设对可达性及空间公平的影响
The impact of intercity high-speed railway construction on accessibility and spatial equity in Beijing-Tianjin-Hebei urban agglomeration
摘要
Abstract
While the development of high-speed rail(HSR)has notably reduced travel time,its implications for equitable accessibility within urban clusters and spatial equity remain critical concerns.The study divides the medium-term and long-term intercity railway initiatives in the Beijing-Tianjin-Hebei urban into three phases from 2016 to 2030.Using road network datasets and socio-economic indicators,accessibility is analyzed through the average travel time,while spatial equity is evaluated using the accessibility dispersion index and the territorial cohesion index.The results indicate that the intercity HSR network substantially improves accessibility and strengthens regional connectivity at the municipal level.From 2016 to 2023,average intercity travel time decreases by 33.1%at the municipal level and 20.7%at the county level.From 2023 to 2030,accessibility increases by 9.5%at the municipal level and 10.2%at the county level,with a primary emphasis on improving the city connectivity in the capital region.Spatial equity and cohesion within the region are enhanced at the municipal level,whereas equity at the county level tends to polarization.The study recommends that both national and local governments should consider policies and coordination measures at different planning levels to promote spatial development and regional equity.关键词
