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。According to the remote sensing image of Huangzhou district in 1995, 2005 and 2014, the urban construction land of the three years was extracted from the Google Earth image by using the monitoring method of human-computer interaction and referring to the city planning drawing. The fractal theory and spatial syntax are applied to the quantitative analysis of the internal and external forms of Huangzhou, and the collaborative development characteristics of the internal and external forms are made by using the comprehensibility evaluation. The characteristics and driving mechanism of the urban form of Huangzhou in the middle and small cities of China are for the study. The internal structure of the city is expanding from west to east, and the road-microgrid structure is becoming more and more perfect. The internal and external form synergy is greatly reduced and the comprehensibility is not as good as that of the past. Finally, it explores its driving mechanism, and the form of Huangzhou is the result of the combination of various factors such as social economy, natural environment, traffic network, urban planning and so on.
