【摘要】：根据1995、2005、2014年黄州区遥感影像,使用人机交互的监督分类方法并参照城市规划图、Google地球影像提取出3个年份的城市建设用地。将分形理论和空间句法综合运用于黄州城市内、外部形态的定量分析,提出使用可理解度评测内外部形态的协同发展特征,对我国中部中小城市黄州的城市形态演化特征及驱动机制进行研究。结果表明:城市总体向东南偏东和东北方向发展;城市外部形态的紧凑度、分形维数下降明显,形状指数由降转增,外部轮廓呈现出"马蹄形——斧形——掌形"的变化特征;城市内部的经济活动中心由西向东扩展,道路主-微网格结构日益完善;内外部形态协同性大幅下降,可理解性不如从前。最后探讨其驱动机制,黄州城市形态是社会经济、自然环境、交通路网、城市规划等多种因素共同作用的结果。
[Abstract]:According to the remote sensing images of Huangzhou District in 2014, 1995 and 2005, the supervised classification method of human-computer interaction was used and the urban planning map was consulted. Three years of urban construction land were extracted from Google images. Fractal theory and spatial syntax were applied to the quantitative analysis of the external morphology in Huangzhou city. The cooperative development characteristics of internal and external forms are evaluated with comprehensibility. The evolution characteristics and driving mechanism of urban morphology in Huangzhou, a small and medium-sized city in central China, are studied. The external shape of the city is compact, the fractal dimension decreases obviously, the shape index changes from descending to increasing, and the outer contour shows the characteristics of "horseshoe shape-axe shape-palm shape". The center of economic activity in the city extends from west to east, and the structure of the main-micro-grid of the road becomes more and more perfect. The synergy of internal and external forms has declined significantly, and the understandability is not as good as before. Finally, the driving mechanism of the urban form of Huangzhou is social economy, natural environment and transportation network. The result of the combined action of many factors, such as urban planning.
