文章摘要：利用成本加權柵格法分析非高鐵與高鐵條件下長三角地區(qū)5大都市圈的最短旅行時間的可達性和一日交流圈等時圈格局變化。結果顯示：1都市圈高鐵站點城市成為時間收斂最大受益者,非站點城市可達性也有所提高,但幅度較小。25大都市圈等時圈均沿高鐵線呈軸向態(tài)勢向外推移明顯,表明高鐵對都市圈空間拓展具有較強的軸向引導作用。3高鐵擴展了5大都市圈一日交流圈范圍,覆蓋范圍幾乎達到100%,1h和2h等時圈覆蓋范圍均有不同程度擴展,表明高鐵條件下,都市圈內(nèi)部城市以及都市圈之間重要核心城市的時間距離拉近,實現(xiàn)跨城市當日流動,形成＂同城效應＂。

Abstr：This paper integrated method of cost weighted raster analysis was designed and applied to generate five metropolitans’ daily communication rings with and with the operation of high- speed railways in Yangtze River Delta region. The valuation of accessibility was conducted with a coefficient based on the shortest travel time. After the valuation, differences between accessibility patterns with scenarios with and without high-speed railways were analyzed,and influences of the high-speed railways on five metropolitans’ accessibility were discussed. The results indicated that cities along the high- speed railways became the biggest beneficiaries of time convergence, the accessibility of none station cities also promoted while in minutely. The isochronous rings of five metropolitans evolved outward along the high-speed railways, and the spatial scope showing the extend trend along the high-speed railways. High-speed railways would expand the isochronous ring, and the coverage of five metropolitans’ daily communication ring almost attained one hundred percent in scenario of high- speed railway. The coverage of 1 and 2 hour- isochronous rings extended in varying degrees. This indicated that daily flow across the cities, and＂City effect＂can be achieved with the closer time distance among main cities inside or outside the metropolitans.
