摘要
空间句法轴线地图模型为研究城市空间形态提供了一种独特的方法,但其在方格路网城市空间分析中的应用存在若干技术缺陷,影响了其在现代城市空间研究应用中的可信度。文章认为,这一问题可以通过考虑宽度不同的道路之间的交叉、穿越、分割关系,设定空间竞争原则,改进轴线地图的空间单元划分方法得以解决。对若干方格路网城市原型的比较试验表明,经改进的方法可以更有效地反应方格路网城市的构型特征。文章进一步对南京城市做了实证验证,结果证明,经改进的方法所得到的空间集成度指标与城市商业布局之间的关系更加精确,而空间局部集成度(r=3)与步行人流量之间相关系数的R2值也明显高于传统方法。
A new space partition method of axial map is proposed to avoid the inconsistencies appearing in space syntax when dealing with the regularly gridded urban texture, which limits the use of space syntax in many modem cities. In the new method, the wider road divides the narrower one into two space partitions and the roads with the same width are divided up by each other. The new method is examined by the comparison of a series of regularly gridded urban prototypes and shows more acceptable results. It is also proved that the R^2 value for correlation coefficient between local integration index （r=3） and pedestrian flux is significantly higher than the traditional method when it is tested in certain area with regularly gridded urban texture in the inner city of Nanjing.
