Evaluation and Optimization Model of Green Space Ecosystem Services in Urbanization Process

In the rapidly advancing wave of urbanization in China, a series of urban environmental problems have gradually surfaced, seriously threatening the quality of life of residents and the sustainable development of cities. In this context, the importance of urban green space ecosystems as the "lungs of the city" is increasingly prominent. Green spaces not only effectively absorb pollutants from the air, regulate urban microclimate, and alleviate the heat island effect, but also provide valuable leisure space and spiritual comfort for urban residents, playing an irreplaceable role in improving citizens' well-being and beautifying urban landscapes. This article explores in depth the evaluation methods of green space ecosystem services in the process of urbanization, aiming to comprehensively analyze the service functions and values of green space systems in various aspects such as air purification, climate regulation, biodiversity conservation, leisure and entertainment, and cultural education through scientific quantitative methods. At the same time, this article also constructs an optimization model for green space ecosystem services, aiming to guide urban planners and managers on how to scientifically layout green space systems, achieve maximum utilization and rational allocation of green space resources.
