Influenced by economic development and the information society, more elderly people are more willing to go to urban parks for activities. Among them, comprehensive parks are the first choice for most elderly people. However, most urban parks are currently constructed according to adult. There are very few researches and practices on the age-appropriate design of urban parks, and the richness, safety, and comfort of the elderly’s activities cannot be guaranteed. In view of this situation, this paper studies the aging-appropriate design of urban comprehensive parks and proposes an aging-friendly design scheme for urban park landscapes based on computer virtual simulation technology from the four aspects of layout, type, distribution, and construction, systematically researched the activity space system for the elderly, and realized the virtual simulation display effect of urban park landscape. Research shows that the design scheme proposed in this paper solves the problem of interaction between buildings and users, breaks the traditional landscape design presentation form, and saves the cost of modification and production of traditional models, which is suitable for the aging and popularization of future urban park projects, providing an effective reference.
