Urban morphology could be described as the result of various shaping processes in social level at a given place through time, which especially developed from the motivation of internal and external economic development and urban policy control. Focusing on urban policy in China, taking Nanjing City as an example, our project investigated related urban policies in the national, provincial, and local level, thereby figuring out three classifications related to urban morphology, i.e., directly impact, indirect impact, and no impact, which are mainly included in mandatory provisions of land use, building layout, and guiding provisions of urban landscape organization. Finally, based on the case validation, through the establishment of morphological laws and regulations model and Spacemate correlation evaluation chart, the comparative analysis method is used to analyze the actual situation of the studied case and the theoretical model complying with the laws and regulations from aspects of the plane form, building layout of the block, and the form of street interface. The study verifies the impact of urban policies on urban morphology, which not only has reference value for the revision of relevant urban policies and urban design regulations in our country, but also has theoretical and practical signifi cance for improving urban environmental quality.%城市形态被描述为在特定的地方,受到社会、经济、政治、环境等因素综合影响的产物,尤其受到来自于内外部经济发展动力和城市法规的影响与控制.聚焦中国城市法规,以南京市为例,本研究首先梳理了国家、省级及地方城市的相关法规条文,对涉及城市形态的划分为直接相关、间接相关和不相关三类,并总结出这些条文中对城市形态的规定,包括土地使用、建筑布局等强制性规定和城市景观组织等引导性规定.最后通过案例验证,在建立形态法规理论模型和空间关联评价图表的基础上,采用对比分析法,从城市街区平面形态、地块建筑布局形态及街道界面形态等方面,对案例的实际现状与符合法规的理论模型进行图示比较,并结合关联评价图表分析城市形态和法规的关联性.本文研究验证了城市法规对城市形态的关联影响,不仅对我国相关城市法规和城市设计规定的修订具有参考价值,而且对提升城市环境质量具有理论与现实意义.
