摘　　要：基于区域交通网络研究现状,以休宁县域国道、省道、县道和乡道构成的交通网络为数据源,根据空间句法理论,利用Ucl Depthmap软件平台从整体路网、分等级路网、各建成区路网3个方面多视角综合测度和量化描述休宁县域交通网络;通过对整合度、连接度、平均深度值等指标的解读,分析休宁县域的空间可达性及其分布特点,并计算出各路段的指标数值,判断各等级道路结构的合理性。结果表明,休宁县域道路呈自由放射路网布局形式,整合度、空间智能度较低,道路系统形态缺乏合理性,可达性一般。对现存的问题进行总结,并提出相应的调控及优化策略,以期为城市的空间发展交流、规划建设提供参考。Based on the current research status of regional transportation networks,the transportation network composed of national roads,provincial roads,county roads,and township roads in Xiuning County is used as the data source.According to spatial syntactic theory,the Ucl Depthmap software platform was used to comprehensively measure and quantify the Xiuning County road traffic network from three perspectives:Xiuning County′s overall road network system,hierarchical road network system,and road network system of each built-up area.By interpreting indicators such as the integration coefficient,connection value,average depth,and other correlation coefficients,this study analyzes the spatial accessibility and distribution characteristics of the whole county in Xiuning,and calculates the variable values for each segment to determine the rationality of the road structure at different levels.The results show that the layout of the Xiuning County road is a free-radial network layout with low integration,low spatial intelligence and ordinary accessibility,lacking rationality in the shape of the road system.Finally,the existing problems are summarized,and the corresponding regulation and optimization strategies of Xiuning County road network are proposed,aiming to provide a reference for the spatial development exchange,planning and construction of the city.
