高速交通对山东省城市形态时空演变的影响

Impact of High-speed Traffic on the Temporal and Spatial Evolution of Urban Forms in Shandong Province

为研究高速交通对城市形态时空演变的影响,基于1995—2018年山东省城市建设用地数据,选取城市形态扩张速度指数、城市形态扩张强度指数、城市形态紧凑度指数和分形维指数等指标,从时空角度分析高速交通对山东省城市形态演变的影响。结果表明:(1)山东省城市建设用地分散,紧凑度低;(2)山东省城市发展规模小,城市扩展速度慢;③大城市形态受高速交通分割严重。针对高速交通对山东省城市形态演变带来的问题,提出了山东省高速交通与城市和谐发展的对策性建议。

In order to study the impact of high-speed traffic on the spatial and temporal evolution of urban morphology,based on the data of urban construction land use in Shandong Province from 1995 to 2018,this paper analyzes the impact of high-speed traffic on the evolution of urban form in Shandong Province from the perspective of time and space by selecting indicators such as urban form expansion speed,urban form expansion intensity,urban form compactness index and fractal dimension index.The result shows that:①Urban construction land is scattered and low in compactness;②The scale of urban development in Shandong Province is small and the rate of urban expansion is slow;③The shape of big cities is severely divided by high-speed traffic.Finally,in view of the problems brought by high-speed traffic to the evolution of urban form in Shandong Province,some suggestions are put forward for the harmonious development of high-speed traffic and cities in Shandong Province.
