Study on the Functions and Design Techniques of Urban Parks in the Context of Post-1949 Urban Development - Case Study of Xian, China

The urban park is an important part of the urban green space system and an essential factor in promoting sustainable development and urban transformation. The functions and corresponding design methods of urban parks also reflect the background and development requirements of different periods. In response to the requirements of urban development in different periods, parks in Xian have gradually changed from a single function of recreation to a function of cultural exchange and, in recent years, to a function of habitat protection. In order to better discuss and analyze characteristics and provide inspiration for further study, the article aims to divide the period from 1949 to 2020 into four stages according to the historical background, and make a comparative analysis according to the corresponding overall planning requirements and examples. The study will combine data with field visits to representative parks from four periods and analyze the relevance of their design and impact to the requirements of the times.The renovation of ancient gardens lays the foundation for the construction of parks, the protection and development of cultural heritage sites increases the role of parks in cultural construction, and the development and construction of ecological wetlands increases the function and role of parks in the construction of ecological civilisation. It can be concluded that the function of the park is also correspondingly related to its design approach.
