Research on Landscape Design of Xi'an Metro Construction Project

The construction of rail transit has the characteristics of huge investment, long cycle, and extensive impact, which leads to the long-term occupation of urban space by subway construction sites, causing significant impacts on urban landscape and residents' lives. Taking Xi'an as an example, as a key city for the development of the northwest region, the expansion of its subway network is an important symbol of regional development and also indicates that subway construction sites will become a norm in the city. The report of the 20th National Congress of the Communist Party of China emphasizes the importance of green development, and exploring the optimization design of subway construction sites and their surrounding landscapes has become particularly important. Through observations during school and daily life, as well as on-site inspections and questionnaire data analysis of the construction projects of Xi'an Metro Line 6 and Line 8, this study found that the main environmental problems include poor environmental experience quality, blurred landscape features, difficulty in standardizing design, difficulty in meeting diverse needs with landscape measures, and lack of consideration for urban landscape system integration. Based on these issues, corresponding solutions are proposed: emphasizing the integration of external landscape design with urban and corporate culture, enriching functionality to achieve a win-win situation for economic and social benefits, pursuing standardization and sustainable development of design, adopting diversified design to meet the needs of different groups of people, and achieving unity between landscape design and the overall urban landscape. The aim of this study is to optimize recycling and improve the landscape comfort of subway construction sites and along the line by adopting measures such as green building technology and movable assembly landscape design, and to combine them with historical and cultural heritage to achieve effective integration of commercial advertising and public welfare. This will not only enhance the urban image of Xi'an and even Shaanxi, but also promote the experience gained to relevant projects nationwide and even globally, serving as an important public welfare publicity window and experience demonstration.
