摘要:
以兰州-西宁城市区域交通路网为例,基于空间句法模型、日常可达性模型和等时圈通过特征点算法,试图运用GIS技术将节点、轴线和域面结合起来对通达性进行全面阐述,多视角综合测度区域路网通达性的空间格局。研究结果表明:1.区域路网体系较为完善,路网线段集聚相对明显;线段式空间伸展格局呈"点-轴"状,轴线式空间伸展格局呈"干-枝"状,初步形成核心、过渡、外围三大等级圈层以及"X"字型路网骨架,区域交通运输与城镇发展水平表现出较强的共轭协同发展关系。2.等时圈沿国道、省道、县道扩散表现连续,沿封闭铁路、高速公路扩散出现跳跃,其等时圈空间特征多呈现"枝-叶"状。城镇日常可达性在较大程度上取决于区域中心性、周...
Abstract:
Accessibility is a research topic in the field of human geography, urban and regional planning, and transportation economics. With rapid increasing of application demands and unceasing development of technology researches, accessibility measurement approaches also develop swiftly and the methodology is being formed. This paper attempts to combine nodes, axes and area to elaborate accessibility in Lanzhou-Xining city region. Based on space syntax, daily accessibility and isochronous rings according to calculation of feature points, the spatial pattern of accessibility of road network are evaluated synthetically in multiangle. The result shows: (1) The system of road network is better, and the concentration of road network is obvious. The spatial pattern of segment type stretches along the“pointaxis”style while the spatial pattern of axis type stretches along the“trunkbranch”shape. Core ring, transition ring, and periphery ring of three grade level as well as“X”shape of road network is preliminary form. It is shown to have a strong reciprocalcoordinate relationship between regional accessibility pattern and the entire development level of Lanzhou-Xining city region. (2) Spatial diffusion of isochronous ring along the national road, provincial road, and county road is continuous while Spatial diffusion of isochronous ring along close railway and highway is leaps, which results in spatial characteristics of isochronous ring show“branchleaf”shape. Urban daily accessibility, to a great extent, depends on the regional geometric centre, the development level of the surrounding road network and intensive degree of urban or town. It is obviously for regional road network to polarization of singlecenter. The control action of Lanzhou city to the road network is apparent. (3) The spatial distribution of regional accessibility is different, so that the fragmentation of the core plate is obvious and the continuity of the extend plate is apparent. The regional accessibility is an extremely significant difference so that appear extremely high value zone and very low value zone. The area with value of medium or high is broken between Lanzhou area and Xining area, and the southern area with value of extremely low become into contiguous zone. Therefore, it is urgent for realization of moderate diversion of traffic flow to accelerate construction of belt highway and ring network in Lanzhou area, and it is useful for regional integration of Lanzhou-Xining city region to promote construction of Lanzhou-Xining highgrade rapid transit, and it is necessary for Linxia city as the southern regional center to promote construction of Lanzhou-Chengdu railway and Lanzhou-Mohan highway.
