Abstract:As an urban theory built on the criticism of city/non-city duality, Planetary Urbanization advocates for the study of non-city territories and proposes operational landscape in a global scale,demonstrating its close relationship with the discipline of landscape architecture. New theoretical trends stem from Planetary Urbanization,including planetary ecology,planetary architecture and planetary infrastructure,provide new manifestation and manipulation methods for the education and practice of landscape architecture,as well as motivate collaboration and integration between multiple disciplines.With its strong characteristic of synthesis and inclusiveness,landscape architecture is taking a critical responsibility in the building of global environment under a planetary perspective.
