The Ecological Green Integration Demonstration Zone (EGIDZ) is in the Yangtze River Delta, one of the fastest growing regions in China. With ongoing rapid urbanization, the unique green–blue structure of water townships in the area has experienced severe human disturbance, which has resulted in habitat fragmentation, water pollution, ecosystem function decline, and biodiversity loss. The monofunctional municipal infrastructure lacks ecological efficacy, while the traditional concept of green infrastructure faces many limitations and adaptability in dealing with complex urban environments. In this context, we introduce the emerging concept of landscape infrastructure (LI), a soft engineered social-ecological-infrastructural system, as a wealth of inspiration and multiangle design solutions to address this challenge. As a performative structure medium, LI has the potential to incorporate all infrastructures (e.g., green and gray) across the spectrum of the urban territory. The study was carried out mainly through remote sensing and GIS technology. In the research process, (i) the ecological sources were identified based on morphological spatial pattern analysis (MSPA) and landscape connectivity, (ii) a resistance model, minimum ecological cost path, and gravity model were used to develop ecological corridors and the green infrastructure network, and (iii) green infrastructure networks were integrated with sociocultural factors to form hybrid multifunctional LI networks.
