Walter Greiner,Joachim Reinhardtctive features of ecological urbanism in many ways. In ecological urbanism, cities are interpreted as ecosystems. These are human and nonhuman systems that co-exist to simultaneously provide and access ecosystem services symbiotically. It is argued in ecological urbanism that there is an interface b作者: Costume 時間: 2025-3-22 18:43 作者: Charade 時間: 2025-3-22 23:03 作者: 階層 時間: 2025-3-23 01:46 作者: 推延 時間: 2025-3-23 07:50 作者: Lethargic 時間: 2025-3-23 10:31
