An evaluation of the ecological and environmental security on China’s terrestrial ecosystems

Abstract With rapid economic growth, industrialization, and urbanization, various ecological and environmental problems occur, which threaten and undermine the sustainable development and domestic survival of China. On the national scale, our progress remains in a state of qualitative or semi-quanti...
