摘要介绍了空间句法理论和方法,对长沙大学城的交通网络进行了提取轴线地图、句法分析、解读指标变量、数据统计等分析,宏观上分析了研究区的路网空间结构,微观上分析了区域内的重要节点.并结合传统的交通学研究方法,对研究区交通状况进行综合评价,揭示其存在辨识度不高、支路拥堵、交通混杂、校园道路对城市道路过度依赖等问题,提出了规整路网、保护标志性地物、局部限制交通准入、疏导途经校园的城市路段、促进校园内部道路网络化等建议.

AbstractThe theory and method of space syntax were introduced, and a series of operations such as axis map extraction, syntactic analysis, indicator interpretation and data statistics were done to the traffic network of university town in Changsha. In macro sense, the spatial structure of the traffic network were analyzed in the studied area. In micro sense, some important places were analyzed. Besides, combining with the traditional traffic science, the traffic conditions of the studied area were comprehensively evaluated, some existing problems were revealed such as low intelligibility, traffic jam, traffic chaos, campus roads excessively dependence on urban roads and so on. Then, some advices were put forward such as restructuring road network, protecting landmarks, setting up access rules, grooming urban roads through the campus, and improving campus roads networked, etc.

传统城市交通空间研究受地理学和建筑学等的影响,相对更注重定性描述,对定量分析的应用稍显不足.空间句法理论则注重变量分析和图示表达,将其运用于交通学领域,有助于城市交通空间研究的定量化和可视化.长沙大学城地处岳麓山风景名胜区,且高校推行开放式办学理念不设置围墙和大门,使得区内交通状况复杂而特殊,仍有较大的改善空间.
1空间句法基础理论
1.1定义
“句法”,是指句子中的词语根据逻辑关系和语法顺序排列在一起,形成完整的句子结构,以表达某种含义.“空间句法”则是把单个空间比作句子中的词语,根据相互的位置关系和一定的规则连接在一起,形成空间网络,呈现空间形态,营造一个能与人的主观心理产生互动的空间系统.
