目前有关用户健康赋能的研究多以从用户自身特质及外部因素对其赋能的影响探究为主，知识服务作为赋能用户的重要手段之一却鲜有研究提及。文章旨在构建基于用户健康赋能的健康领域知识服务模式，以期通过健康领域知识服务模式的改进，增强健康领域知识服务赋予用户管理自身健康状况、参与健康问题决策的能力。首先，在梳理用户健康赋能和健康领域知识服务现状的基础上，明确面向用户健康赋能的知识服务目标；其次，刻画了用户的健康知识需求会随检索进程的推进而发生变化的现实情况；接着，提出了能够满足用户健康知识需求变化的知识提供模型，并给出了基于知识服务的用户健康赋能机制；最后，给出了用户表达知识需求与知识资源的匹配流程，并构建了面向用户健康赋能的健康领域知识服务模式。

Current research on user health empowerment mainly focuses on the influence of users' attributes and external factors on their empowerment, but knowledge services as one of the important ways to empower users have rarely been mentioned. This paper aims to develop a health domain knowledge service model based on user health empowerment, to empower users to manage their health conditions and participate in decision-making on health issues. Based on the current research on user health empowerment and health domain knowledge services, we propose a user classification based on knowledge needs and construct a corresponding knowledge provision model by clarifying the objectives of user health empowerment-oriented knowledge services; secondly, we portray the change process of users' health knowledge reserves in the process of searching for health information and point out that the types of knowledge need to which users belong will change as the search process progresses. Finally. The matching process between users' expressed knowledge needs and knowledge resources is given, and a health domain knowledge service model for users' health empowerment is constructed.
