My topic is on the optimization and improvement strategies of urban ecological space, optimized suggestions are made from the combination of urban growth，aesthetics，intelligence and digitalization. The raising of this issue is an important guiding principle for the creation of sustainable and livable cities. To achieve this, urban growth and aesthetics must be integrated in harmony with modern technology, especially intelligence and digitalization. This combination can promote a more resilient and efficient urban ecosystem while improving the quality of life of residents. The first to be planned urban growth is focused on sustainability and ecological balance. Among them, strategies involving green spaces, water, biodiversity cities. Such spaces provide important ecological services such as air purification, temperature regulation and water management, even also providing recreational and social benefits to residents. To optimize these, cities must prioritize ecological connectivity and resilience to ensure that urban development does not harm the natural environment but enhance it. Aesthetics plays a key role in the optimization of urban ecological space. These spaces should be designed to blend natural elements with urban architecture, creating an environment that is visually pleasing and promotes human well-being. Green spaces, parks and recreational areas should not only provide ecological functions, but also aesthetic experiences, thereby enhancing the relationship between humanbeings and nature. This can be achieved through thoughtful landscape design, the combination of artistic and cultural elements and the preservation of natural landmarks in urban settings. Aesthetic considerations help create a sense of place and foster a sense of community engagement, thus contributing to the overall livability of the city. The integration of intelligence and digitalization is crucial to effectively manage and continuously improve urban ecological space. Advanced artificial intelligence technologies can help monitor and manage the environmental conditions of these spaces. In addition, intelligent systems can also be used to track environmental elements such as air quality, water and biodiversity, so as to intervene in real time and plan for long-term. Digital tools can also enhance public participation, provide citizens with a platform to report on environmental issues, access educational resources, and participate in decision-making processes related to urban ecology. In summary, optimizing and improving urban ecological spaces requires a holistic approach that combines urban growth strategies with aesthetic and technical considerations. By integrating natural, design and digital technologies, cities can create more sustainable, resilient and aesthetic environments that benefit people and the planet.
