【摘要】：以浙江省69个县(市)为研究对象,利用1996、2004、2012年路网数据,借助ArcGIS网络分析功能,采用基于城镇综合发展水平的加权平均旅行时间指标,探讨浙江省综合交通网络中节点城镇可达性及其时空演变特征。研究结果表明:11996—2012年,各城镇可达性均出现不同程度提高,彼此间联系趋于紧密;2城镇可达性存在空间分异,且提升幅度各异,均衡化趋势明显;3城镇可达性空间格局变化大,逐渐向以"四大都市区"为中心向四周递增的"∏型"多级空间结构转变。总体上来看,城镇可达性变化及空间格局演变体现了区域统筹发展的战略要求。
[Abstract]:Taking 69 counties (cities) in Zhejiang Province as the research object, the weighted average travel time index based on the comprehensive development level of cities and towns is adopted by using the road network data from 1996 to 2004 and the network analysis function of ArcGIS in 2012. This paper discusses the accessibility of node towns and its temporal and spatial evolution characteristics in the integrated transportation network of Zhejiang Province. The results show that from 1996 to 2012, the reachability of cities and towns increased to different degrees, and the relationship between them tended to be close. There were spatial differences in the accessibility of cities and towns, and the degree of improvement was different. The trend of equalization is obvious. The spatial pattern of reachability of the three towns changes greatly, and gradually changes to the multi-level spatial structure with "four metropolitan areas" as the center and increasing gradually in all directions. On the whole, the change of urban accessibility and the evolution of spatial pattern reflect the strategic requirements of regional overall development.
