Abstract: During the practices of renewal in city parks, it is technically difficult to coordinate the relationship between protection of history, cultural information, eco-environment and park enhancements. Based on hierarchical idea, this paper analyses the harm of current renewal models to the history, culture and eco-environment in city parks. The basic layer, the protective layer and the expanded layer were set to be different historical stratifications among overall-planning strategy, which forms a kind of organic renewal model for city park based on hierarchical idea. The parts with the value of history, culture, ecology and function among different history stratifications in parks are divided into the open and continuous basic layer and the protective layer. The expanded layer can be employed to enhance the overall-function in the park in order to adapt to new developments. Finally, this application is described through the case study of the transformation in Shanghai Huangxing Park.
