目的 分析仫佬族经典凤纹特征，提出凤纹衍生设计与应用的实施路径，实现仫佬族凤纹文化的活态传承。方法 首先，收集仫佬族凤纹图像，分析凤纹特征并设计核心凤纹;其次，采用形状文法生成单元图案，依据K-means聚类算法提取色彩因子;最后，结合拓扑构型进行凤纹衍生设计创新。结论 凤纹反映了仫佬族人对生活美的寓意追求，形成了尖喙上昂、多冠凤冠、长尾上卷和C形凤身的形态特征，据此提取出核心凤纹、10个基本图形单元和8种代表性色彩因子，完成了凤纹衍生设计，所生成图案融合传统与现代，整体形象生动，精致多彩，展现了中国西南秘境和谐之美并应用于抱枕、手机壳、手提袋等民族文创产品包装中，提升了产品的民族文化内涵和艺术价值。

The work aims to analyze the classic phoenix pattern characteristics of Mulao ethnic group, propose an implementation path for the derivative design and application of phoenix patterns, and achieve the active inheritance of Mulao ethnic phoenix pattern culture. Firstly, the images of Mulao ethnic phoenix patterns were collected, the characteristics of phoenix patterns were analyzed and the core phoenix patterns were designed. Secondly, the shape grammar was used to generate unit patterns and the color factors were extracted based on K-means clustering algorithm. Finally, the topological configurations were combined for derivative design of innovative phoenix patterns. The phoenix pattern reflects the moral pursuit of life beauty by Mulao people, forming the morphological characteristics of pointed beaks, multi crown phoenix crowns, curling-up long tail, and C-shaped phoenix bodies. Based on this, the core phoenix pattern, 10 basic graphic units and 8 representative color factors, are extracted to complete the derivative design of phoenix patterns. The generated pattern integrates tradition and modernity, with a vivid and exquisite overall image, showcasing the beauty of harmony in the secret realm of Southwest China. It is applied to the packaging of ethnic cultural and creative products such as pillows, phone cases, and handbags, enhancing the cultural connotation and artistic value of the products.
