“…Lastly, c 1 J 1 and c 2 J 2 indicate partial differential contrary degree and contrary degree, respectively, and J 1 , J 2 are their coefficients, which are regulated to be minus unity. The water resources vulnerability is generally divided into five levels [14,19], and assuming that x ij (i = 1, 2, . .…”

“…This paper presents the concept of water resources vulnerability, which is the nature and state of a water resources system, wherein, the normal structure and function are compromised by a changing environment. Vulnerability also includes, the sensitivity and adaptation to the disturbance and destruction under a changing environment, the ability to bear and cope with such change, and the level of resilience to damage [12][13][14]19].…”

“…SPA considers both certainty and uncertainty as a system for the purpose of conducting identical-discrepancy-contrary analysis as well as further quantitative mathematical process using a connection number. Because of its realistic approach to deal with uncertainty, SPA has been put to extensive applications in sociology, economics, engineering technology, and management, and has produced numerous research results [14,[27][28][29][30].…”

“…The connection numbers of the vulnerability index with Equation (13), and thereafter, connection entropy of the vulnerability index, are described as follows: (14) where S s1 = a 1ij ln(a 1ij + e) indicates identical entropy, S s2 = a 2ij ln(a 2ij + e) denotes critical identical entropy, and S f 1 = b 1ij ln(b 1ij + e) × I 1 indicates upper discrepancy entropy, Furthermore, S f 2 = b 2ij ln(b 2ij + e) × I 2 implies medium discrepancy entropy, S f 3 = b 3ij ln(b 3ij + e) × I 3 represents lower discrepancy entropy, S p1 = c 1ij ln(c 1ij + e) × J 1 is critical contrary entropy, and S p2 = c 2ij ln(c 2ij + e) × J 2 suggests contrary entropy.…”

This paper establishes a water resources vulnerability framework based on sensitivity, natural resilience and artificial adaptation, through the analyses of the four states of the water system and its accompanying transformation processes. Furthermore, it proposes an analysis method for water resources vulnerability based on connection entropy, which extends the concept of contact entropy. An example is given of the water resources vulnerability in Anhui Province of China, which analysis illustrates that, overall, vulnerability levels fluctuated and showed apparent improvement trends from 2001 to 2015. Some suggestions are also provided for the improvement of the level of water resources vulnerability in Anhui Province, considering the viewpoint of the vulnerability index.

Research Impact Statement: Importance of the MR-SNWDP (middle route of the South-to-North Water Diversion Project) for ensuring available water supplies in Beijing.ABSTRACT: Since its implementation in 2015, the Middle Route of the South-to-North Water Diversion Project (MR-SNWDP) has transferred an average of 45 billion cubic meters of surface water per year from the Yangtze River in southern China to the Yellow River and Hai River Basin in northern China, but how that supply is able to cope with droughts under different scenarios has not been explored. In this study, using the water demand for 2020 as the guaranteed water target, a Water Evaluation and Planning system was used to simulate available water supplies in Beijing under different drought scenarios. In the case of a single-year drought, without the MR-SNWDP, Beijing's water shortage ratio was 16.7%; with the MR-SNWDP, this ratio reduced to 7.3%. In the case of a multi-year drought, without the MR-SNWDP, Beijing's water shortage ratio was 25.3%; with the MR-SNWDP, this ratio reduced to 7.4% and domestic water supply was improved. Our research suggests that to prepare for multi-year drought in the Beijing area, the SNWDP supports increased supplies to the region that would mitigate drought effects. This study is, however, mostly focused on water supply provision to Beijing and does not comprehensively evaluate other potential impacts. Multiple additional avenues could be pursued that include replenishing groundwater, increasing reservoir storage, and water conservation methods. Further research is needed to explore the relative costs and benefits of these approaches.
