Abstract: With the acceleration of urbanization, the concept of healthy city emerges as the times require. In the post epidemic era, China will enter the stage of new public health development, and people pay more and more attention to health. Community park is not only an important aspect of healthy city construction, but also an important part of community life circle. It can meet the needs of improving people's mental health, enhancing physical activity and social interaction. The renewal design of community park guided by public health has become a new research hotspot. Through the Analytic Hierarchy Process (AHP), the evaluation system of community park health benefits was established, and the weight of each index factor was established. The index system includes four aspects: natural elements, activity facilities, spatial connection and experience perception.The index layer based on 18 factors includes the richness of aromatic plant species, the richness of physical activity facilities, the convenience of walking, the connection with other public spaces in the community, the connection with green space around the community, the space security and so on. Taking Dongwangzhuang Community Park in Beijing as an example, the renewal strategy system of community park from the perspective of healthy city is established from three aspects: health benefit evaluation, health function space transformation and healthy lifestyle guidance. The Fuzzy Comprehensive Evaluation (FCE) method was used to generate the questionnaire with the index system. The questionnaire survey was conducted in Dongwangzhuang Community Park. The questionnaire data were collected and calculated to obtain the evaluation results of the current situation of health service benefits of the community park. On the basis of the evaluation results, health oriented, combined with the characteristics of community parks, the health needs of residents' physical health, mental health and social health are concerned, and the health function space transformation strategy is obtained. The strategy is divided into micro strategy, meso strategy and macro strategy. The micro strategy is to enhance the health perception elements. The meso strategy mainly aims at three types of space, including social interaction space, physical activity space and emergency service space. The macro strategy is to build a balanced and convenient green space and slow traffic system at the community scale. In terms of park management and operation, this paper puts forward healthy lifestyle guidance strategies, mainly including community park health activities and park smart management system focusing on public health.
