| Causing profound influence on Chinese society, aging of population has more and more become the serious problem paid attention to by China and the society, which also brings new challenge to urban planning and construction field. The Ministry of Construction and the Ministry of Civil Affairs have issued relevant industrial standards including Code of Building Design for the Old People, in which specific requirements on housing design for the old people were proposed. However, the houses only provided a living environment to the old people. They shall go out to have social interaction and leisure activities. Neverthe-less, these activities must depend on the public space of the community. Therefore, with the development of aging of population, the public space of the community must increase its adaptability to old people and create a safe, comfortable, and interesting activity environ-ment for old people.Taking Chengdu for an example, the paper regards the old people and the public space of their community as the research object. Through the analysis and research on domestic and foreign documents, the evolution and characteristics of public space of Chinese commu-nity as well as the activity characteristics of old people in public space of the community were summarized. Based on this, several classical communities of Chengdu were selected for field investigation from3aspects including foundation year, construction situation of public space, and construction floors. In addition, according to the interview and question-naire with old people in the community, the arrangement, environmental characteristics, and problems in the public space of the community were summarized. In addition, current prob-lems in the community were proposed by connecting the public space of the community with the activity characteristics of old people based on the questionnaire. Besides, corresponding key points for transformation design strategies were proposed to increase the adaptability to aging of population, improve life atmosphere, and create better living environment in the public space of the community. |
