Resilience Assessment of Water Resources System

The resilience perspective, which emphasizes the integrated, systemic concept of human and nature interactions, is increasingly used as an approach for understanding the dynamic of social-ecological system. As the water resources system (WRS) is a social-ecological system, resilience thinking such as Holling’s adaptive cycle has been adopted as a fundamental unit for understanding the water resources system dynamics in this paper. In the adaptive cycle of WRS, the likelihood shift among different phases largely depends on resilience value; and a quantitative method for estimating the resilience of WRS is proposed. The method is related to the degree of change and characteristics of the WRS, and has been applied to identify the phase of WRS in every city in Zhejiang province, China. The results of resilience assessment have also been discussed in terms of adaptive cycle.
