居住区规划控制指标宜居度的灰色聚类评价

A Grey Cluster Analysis of Livability on Residential District Planning Controlling Index

通过对居住区规划控制指标生成过程的分析,指出对人均指标的忽视及经验赋值法是造成目前"以人为本"理念的实现无法得到保证的两个主要原因。采用灰色系统理论方法,分析指标体系的灰度,提出能体现居住区人居物质环境质量的"宜居度"指标,并对其展开定量评价。并经实证研究表明,该方法具有计算简便、分辨率高和原有指标信息利用率高等特点,能降低经验取值的主观性,使其更加有效地指导规划设计工作。

Based on a review of indicators for compiling the existing city planning guidelines in China, this study proposes the concept of people-oriented residential environment can be evaluated by indices of livability in a quantitative way. The study adopts theories and methods of grey system, and tentatively establishes a model for such quantification. Data obtained from real cases are used to test the model, the results indicate that this method has advantages of simple calculation, high resolution, and cost-effective by using large amount of existing indicators of city planning guidelines.
