【摘要】：本文以广东省陆路交通网络为对象,综合利用可达性度量模型对广东省区域可达性进行测算和空间特征分析,并进一步实现广东省省域的等级分区。结果表明,广东区域日可达性和时间可达性呈现出同心圆分布特征,并具有明显交通网络指向性;但在空间、交通网络结构和社会经济等因素的综合影响下,潜力可达性表现出多中心圈层的空间分异特征。研究揭示了广东省区域可达性的空间格局及分异规律,探讨了地理区位和城市发展在可达性空间分异中作用,从而为广东产业布局优化、土地集约化利用以及区域协调发展提供科学参考。
[Abstract]:This paper takes the land transportation network of Guangdong Province as the object, synthetically uses the reachability metric model to calculate and analyze the spatial characteristics of the Guangdong province's regional accessibility, and further realizes the grade division of Guangdong province. The results show that the daily reachability and time reachability of Guangdong show the characteristics of concentric circle distribution, and have obvious traffic network directivity, but under the influence of space, traffic network structure and social economy, etc. The potential reachability shows the spatial differentiation of the polycentric layer. The study reveals the spatial pattern and differentiation law of regional accessibility in Guangdong Province, and discusses the role of geographical location and urban development in the spatial differentiation of accessibility, thus optimizing the industrial distribution of Guangdong. Intensive land use and regional coordinated development provide scientific reference.
