本文通过观察、实验研究空间异用——一种不按设计师的设计意图去使用环境的行为。研究结果表明,“功能固定”是创造环境价值的障碍。限定性空间中产生异用意图的次数高于非限定性空间,而产生有明确主题的异用意图次数非限定性空间又高于限定性空间,这是设计者必须考虑的依据之一。 This article observes and experimentally studies spatial heterogeneity, a behavior that does not use the environment in accordance with the designer’s design intent. The results of the study indicate that “fixed function” is an obstacle to the creation of environmental value. The number of different use intentions in the limited space is higher than the non-restricted space, and the number of non-restrictive spaces with different themes of explicit use is higher than the limited space. This is one of the criteria that designers must consider.
