Abstract:The tianxin park is the first city park of Changsha in Hunan provice, and also one of the earliest modern children's Park in china. In the context of modern city development in Changsha, it has experienced the historical stages of "initial creation", "expansion", "transformation", "stagnation", "rebirth" and so on. Its changes are deeply influenced by the factors of politics, economy, ideology and aesthetic ideas. In this process, the heritage value of the historical garden is finally able to be achieved.The historical change of Tianxin park is a footnote for Changsha's urban development, and Changsha's urban development is a microcosm of urban development in China. Combing this process of change enables us to take a historical view of our urban construction practice: what we have persisted and what we have lost.The construction and maintenance of the historical gardens should not deal with a matter on its merits, and the rapid urbanization process needs systematic thinking.
