2、ralPractice崇礼太子城雪花小镇位于北京 2022 冬奥会张家口赛区核心区的崇礼太子城冰雪小镇的中心地带，是冰雪小镇文创商街。雪花小镇北倚太子城遗址，西临太子城高铁站，四面被群山环抱，遗址和高铁站的两条轴线交汇于此，基地西北低、东南高，高差约12m。设计受精美绝伦的自然造物冰晶雪花的启发，将其几何形状转换成抽象的雪花母题，在水平方向上错缝拼合，四向延伸，立体演变为雪花建筑及街市。天空中飘舞的“雪花”缓落于山谷，成簇成团，渐生出一个冬日山林中的冰雪世界。不同于自上而下的城市规划体系，雪花小镇的生成法则是自下而上，通过几何原型的自然生长来完成的，是一个“自然聚落”。将雪花状的控制网格，以太
