Abstract

Under the background of double carbon targets, the sustainable development of city of major sports events become the focus of global attention. This study focuses on assessing the sustainability of the overall operations within the Qiandao Lake Asian Games Zone. The evaluation utilized an emergy analysis method, resulting in the creation of an emergy chart for the system, and the development of an evaluation index system. The findings indicate that: The environmental load rate of the Qiandao Lake competition area is 50.3, the sustainability index ESI is 0.02, and the system sustainable development emergy index EISD is 0.038. This shows that the environmental pressure in the system is high, the environmental load rate is high, and the environment is in a relatively unsustainable state of development. This is mainly due to the fact that the Qiandao Lake competition area, on the basis of tourism and sightseeing, also has the functions of hosting events and recuperating and vacationing. The operation and maintenance process of sports venues will bring a lot of energy and economic consumption. In the subsequent development, the system can increase the investment of internal renewable resources by expanding the area, reduce the investment of non-renewable resources through green lighting transformation, green transportation planning, photovoltaic system construction, etc. in the competition area, and improve the energy value use efficiency. Strengthen the system's sustainable development capabilities.
