青年群体是公共图书馆必不可少的用户群体。文章通过问卷调查法收集数据，采用聚类分析方法获得公共图书馆青年群体用户的主流类型，描述各类型用户群体的主要特征，形成用户画像。在此基础上，结合近年来国内外的典型服务实践，构建公共图书馆面向青年群体的服务模式。研究发现，公共图书馆青年用户有6个主要类型：多维使用类、自习自修类、书刊阅读类、家庭亲子类、打卡拍照类、文化活动类，各类型用户存在多维度特征差异。面向青年群体的公共图书馆服务，应将服务设施融入青年群体的生活场景；在服务环境上应构建契合青年群体审美的服务场景，营造年轻、现代的服务氛围；构建满足多维需求的服务项目矩阵，提供高品质服务；在服务方式上要适应不同类型青年群体的服务获取行为。

The youth group is an essential user group for public libraries. This paper collects data through questionnaire survey, uses cluster analysis to divide the mainstream types of young users, describes the main characteristics of each type of user group, and conducts user profiling. Based on the above work, this study combines typical service practices at home and abroad in recent years to construct a public library service model for the youth group. This study found that the mainstream youth user group of public libraries consists of six categories: multi-dimensional use, self-study and self-study, book and magazine reading, family parent-child, check-in and photography, and cultural activities. There are differences in multi-dimensional characteristics among each type of user. Public library services aimed at young people should integrate service facilities into their daily lives; In the service environment, service scenes that cater to the aesthetic preferences of young people should be constructed, creating a youthful and modern service atmosphere; Build a service project matrix that meets multidimensional needs and provide high-quality services; In terms of service methods, it is necessary to adapt to the service acquisition behavior of different types of youth groups.
