摘　　要：新区作为当前城市空间扩张的重要形式,对城市空间形态的塑造有着举足轻重的作用。本文阐述了中国新区的规划发展历程;以国家级新区为研究样本,采集地理地貌、街区、建筑轮廓等多源大数据,以边界分形维数、斑块破碎度、地块离散度、街坊形状指数等测度新区的尺度肌理,以城市空间原型拓扑、图底关系转换等分析方法解析新区的空间形态;并从四个不同空间维度对新区的空间形态和尺度肌理展开分析,进而剖析新区空间形态和尺度肌理的生成机制,建构新区空间形态的择优模型,针对当前新区空间规划中所存在的问题提出相应的应对策略。New district, as the important form of the current urban spatial expansion, plays a crucial role in shaping urban spatial form. This paper explains the planning development history of new districts in China. As the research samples of national new districts, the research collects multivariate vector data of geographical features, blocks and architectural contours. Various algorithms, for example, boundary fractal dimension, patch fragmentation, plot dispersion, neighborhood shape index, are used to measure the scale texture of new districts. Urban space prototyping topology and graphical relationship conversion are employed to analyze the spatial form of new districts. The paper analyzes the spatial form and scale texture of new districts from four spatial dimensions, thereby further exploring their generation mechanism. Based on it, the optimal model of new districts＇ spatial form is constructed and corresponding strategies are proposed for the existing problems in the spatial planning of new districts.
