目的 为了实现运河文化遗产的活态传承，并对运河文化基因进行提取及设计应用，提出一种基于层次分析法(Analytic Hierarchy Process, AHP)和形状文法(Shape Grammar)的文化基因提取与运用的方法，并以交通工具的造型设计为例进行设计实践。方法 首先运用层次分析法建立层次结构模型和判断矩阵，对运河文化基因进行筛选排序，获得权重值较高的运河文化基因;其次运用形状文法对所提取出的文化基因进行形状推演，得出特征形状;最后将得到的特征形状转化为3D基本形体，并运用设计语言得到交通工具的造型设计方案。结论 交通工具的造型设计实例表明，应用层次分析法和形状文法，能够有效地实现运河文化基因的提取和设计应用，从而引导运河文化基因的良性变异，为运河文化遗产的创新设计应用提供新的路径和参考。

In order to realize the living inheritance of the canal cultural heritage, and to extract and design the cultural genes of the canal, the work aims to propose a method for the extraction and application of cultural genes based on Analytic Hierarchy Process (AHP) and Shape Grammar and take the modeling design of the transportation vehicle as an example to carry out the design practice. The hierarchical structure model and judgment matrix were established by the analytic hierarchy process, the canal cultural genes were screened and sorted, and the canal cultural genes with higher weight values were obtained. Then, the Shape Grammar was used to deduce the shape of the extracted cultural genes, and the characteristic shapes were obtained. Finally, the obtained characteristic shape was converted into a 3D basic shape, and the modeling design scheme of the transportation vehicle was obtained by the design language.The example of the modeling design of transportation vehicle shows that the application of AHP and Shape Grammar can effectively realize the extraction and design application of cultural genes, so as to guide the benign mutation of cultural genes and provide new paths and references for the living inheritance of cultural heritage.
