ASSESSMENT ON ACCESSIBILITY OF WANJ IANG CITY BELT UNDER THE BACKGROUND OF TAKING OVER INDUSTRY TRANSFER OF THE YANGTZE RIVER DELTA
以时间和费用为指标，结合空间分析与网络分析，研究了长三角12个城市进入皖江示范区的可达性与通畅性，发现可达性受空间距离和路网影响，形成四类城市带，且时间与费用可达性呈现双核心-孤岛圈层结构。
In the thesis,under the background of Wanjiang representative area taking over industry transfer of the Yangtze River Delta,aiming at logistics and passenger flow,we research accessibility and smooth in the representative area on the basis of index of time and fare with spatial Analysis,network analysis and ESDA.The results show that on the whole accessibility entering the representative area from 12 towns of the Yangtze River Delta is based on spatial distance.Road network leads to local change of it.Road network and spatial distance form four city zones of accessibility.The 4-city zones parallel 12 towns entering Wanjiang representative area in the Yangtze River Delta in northeast—southwest,and its local contour follow with directivity of height class roads obviously;On smooth of passenger flow,accessibility spatial distribution of time and fare presents similarities and differences: both of them form circles of double cores—isolated island;Spatial distribution of time accessibility presents directivity of high-way and spatial distribution of fare accessibility presents directivity of railway.Towns in the area represents positive spatial autocorrelation,local areas have obvious difference.
