As the fundamental spatial unit of daily life and social governance for urban residents, the urban community plays a crucial role in shaping the quality of life and promoting sustainable urban development. It serves as an essential carrier for meeting human needs, fostering social interactions, and ensuring the healthy and sustainable growth of cities. However, with the rapid pace of urbanization, significant environmental challenges have emerged, including the loss of ecological land, the intensification of the urban heat island effect, an increased risk of waterlogging, a decline in biodiversity, and the spread of allergenic plant pollen. These issues not only degrade urban living environments but also pose serious threats to public health and ecosystem stability. Given these pressing challenges, it is imperative to thoroughly investigate the changes in green infrastructure within urban communities and to identify the key driving factors influencing these changes. Understanding these dynamics will help in the development of effective strategies for improving urban living environments and enhancing ecosystem services. This study aims to explore the complex interactions between landscape patterns, ecological processes, and ecosystem services in urban communities. Specifically, it seeks to uncover the coupling mechanisms between 3-D landscape patterns and critical ecological processes such as hydrothermal regulation, allergenic plant pollen transmission, and biodiversity maintenance. The primary objectives of this study are as follows: To analyze the spatial characteristics of urban communities in different ecological regions across China and to investigate the intricate relationships between landscape patterns, ecological processes, and ecosystem services. By doing so, we aim to establish a scientific foundation for urban ecological research and planning. To develop innovative technologies for optimizing 3-D landscape patterns and creating environmentally friendly urban spaces. This includes designing solutions for hydrothermal balance, mitigating allergenic plant pollen dispersion, and advancing intelligent monitoring systems for biodiversity conservation and ecosystem service management. To implement and demonstrate urban community renewal and management strategies by integrating ecosystem service improvement technologies in typical urban communities. Through pilot projects and case studies, we seek to provide scalable and practical models for sustainable urban development. By addressing these objectives, this study aspires to contribute to the advancement of urban ecological science and the implementation of sustainable urban planning practices. The findings will not only support the creation of healthier and more resilient urban communities but also offer valuable insights for policymakers, urban planners, and environmental scientists. Ultimately, by integrating ecological principles into urban development, we can foster a more harmonious relationship between urbanization and nature, ensuring a sustainable and livable future for all.
