The green space formed by the on-site disposal of solid waste is a type of difficult urban site. In the process of rapid ecological restoration and landscape construction of such sites, the improvement of biodiversity of such green space habitats is particularly important for accelerating the construction of green, low-carbon, andwaste-free cities. The author team selected Tianjin Nancuiping Park, Shanghai Yanzhong Green Space, Jiangsu Wuxi Jinkui Park, and other green spaces for solid waste disposal as research objects, conducted in-depth research on plant community landscape construction, vertical terrain remodeling and water-saving supply from the perspective of biodiversity, and put forward relevant strategies suitable for such green space habitat construction, including plant selection and community structure optimization methods; (Terrain slope control) and measures for layered construction of terrain pile; Combined with the artificial intelligence control technology, the combination of various ecological technology means, and the treatment of the hydrological balance strategy within site, finally forming a safe, stable, sustainable recycling ecological environment of the regeneration site.
