目的 针对大运河文化资源在设计转化中的不确定性问题，提出基于可拓语义分析的大运河文化创意产品设计方法。方法 选取具有代表性的一类大运河文化，分析其文化特征并提取词汇语义，进一步构建可拓基元模型;将词汇语义转化为图解语义，计算图解语义的可拓设计区间，量化文化与特征词汇的关系;通过形状文法演变得到新的设计元素，以天津北辰农民画为例，开展设计实践进行验证。结论 可拓语义分析在文化创意设计中有较强的指导性和可行性，可以为大运河文化等线性文化资源的设计开发提供研究思路。

The work aims to propose a method of Grand Canal cultural creative product design based on the extension semantic analysis to address the uncertainty of the Grand Canal cultural resources in the design transformation. First, a representative type of Grand Canal culture was selected to analyze its cultural characteristics and extract the semantics of the words to further establish an extension representation model; Then, the semantics of words was transformed into graphical semantics to calculate the extension design interval of characteristic words and quantificat the relationship between culture and characteristic words; Final, new design elements were obtained through the evolution of shape grammar, to carry out design practice for verification with the Tianjin Beichen peasant painting as an example. The results show that extension semantic analysis has strong guidance and feasibility in cultural creative design. It can provide research ideas for the design and development of linear cultural resources such as the Grand Canal culture.
