基于主成分分析法的城市街道开放空间活力的量化评价研究

摘要

为量化评价城市街道开放空间活力,从使用者的角度构建起以安全性、功能性、舒适性、观赏性4个维度的城市街道开放空间活力评价指标体系,以调查问卷的形式获取基础数据,应用主成分分析法,借助spss19.0数理统计分析软件,对所得数据进行统计分析,获得城市街道开放空间活力评价指标权重值,进而构建起城市街道开放空间活力的量化评价系统.为城市街道开放空间的评价与改造设计提供理论依据与数据参考.%To quantify open space vitality of urban streets,the evaluation index system of open space vitality of urban streets with four dimensions of safety,functionality,comfort and ornamental from the user' s point of view was established,the questionnaire was used to obtain the basic data,and the principal component analysis with the help of spss 19.0 was used for statistical analysis to obtain the weight value of open space vitality evaluation index of urban streets,then,a quantitative evaluation system for the open space of urban streets was established.The system provides the theoretical basis and data reference for the evaluation and design of open space of urban streets.
