基于空间句法的米脂县城空间形态优化策略研究

摘要

Space syntax provides strong support conditions for the quantitative study of urban space. In this paper, taking Mizhi County as the research object, the spatial axis model is established by using the space syntax analysis technique and chosing three parameters to carry out the research----the global integration value, the local integration value, and the intelligibility. Then the paper carried out quantitative analysis and group comparative study of the spatial form of status in 2009 and 2014, the spatial form of over-all plan in 2009 and 2014. With all this work, the space form trends of Mizhi County and the response of overall plan in 2009 and 2014 can be found. Accordingly, optimization programs are brought forward. In the end, the paper tested the programs by space syn-tax.%空间句法为城市空间的定量化研究提供了有力的支撑条件。以米脂县城为研究对象，通过空间句法分析工具，建立米脂县城的空间轴线模型，并选取全局集成度、局部集成度和智能度三个参数，对2009年现状空间形态与2014年现状空间形态、2009版总体规划空间形态与2014版总体规划空间形态进行定量化的分析与分组比较研究。在此基础上，深入剖析米脂县城的空间形态发展趋势以及两版总体规划对该趋势的应对，并在2014版总体规划的基础上提出米脂县城空间形态的优化策略。
