Restoration of Degraded Ecosystem: A Pathway to Sustainability

The concept of sustainable development, despite theoretically faultless, is less practicable due to its abstract quality. This paper cites a degraded small drainage area to analyze how the ecosystem, through controlling, has evolved from a seriously degraded baseline to a weak, and further a strongly sustainable status, by observing the change of I/O relationship. Accordingly, this paper proposes a conceptual model of ecosystem degradation and the sustainability, and divides 5 types of system states and finally, explores the sustainable restoration model of the sample.
