摘　　要：通达性被认为是评价交通网络的方法中一项综合的、直观的评价指标,并越来越多地被应用到城市规划、区域空间结构与区域经济发展等多种领域。以山东半岛蓝色经济区陆域范围为研究区,通过运用空间句法模型和网络分析算法,获取路网集成度和等时圈数据并进行GIS可视化表达,定量分析研究区路网发育的空间结构性规律。研究结果表明:(1)蓝色经济区内路网体系发育较为成熟,路网线段集聚明显;线段式空间分布格局呈"点-轴"状发散,轴线式空间分布格局呈"干-枝"状发散,形成了区域内部的核心圈与外围圈的互连互通;(2)城镇区域可达性在较大程度上取决于区域中心性和周边路网发达程度,而青岛市和潍坊市位于区域的核心位置,通达性好且对整个区域路网的控制作用较为突出。Accessibility is a comprehensive and intuitive evaluation index in traffic network,and it had been widely applied to urban planning,spatial structure,regional economic development and many other fields.Taking Shandong Peninsula Blue Economic Zone as an example,we obtain a series of traffic integrations and the same time circle data based on geometry and network analysis algorithm.The proposed models are then applied to examine the spatial structural properties of the road network of Shandong Peninsula Blue Economic Zone.The results are shown as follows:(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.This formed the interconnection between the core ring and the outer ring within the region.(2)Urban accessibility,to a great extent,depends on the regional geometric Centre and the development level of the surrounding road network.Because the core position of Qingdao and Weifang city in the whole area,their accessibility and the control effect on the regional road network is more prominent.
