Operating mechanism and set pair analysis model of a sustainable water resources system

In view of the uncertainty of evaluation indicators for water resources carrying capacity the theory of set pair analysis is adopted. The samples are preliminarily classified by calculating the connection degree between the samples and evaluation indicators. Then the samples are further ranked through the identity, difference and antagonism set pair analysis. The weights of evaluation factors in the model are obtained from the avail value of data reflecting the information entropy, by which the weight allocation is more reasonable. The application result of this model to an example is compared with those obtained from integrated evaluating methods and the attribute recognition method. It shows that the proposed method is practical and reasonable.

Sustainable Water Resources

Based on the studies on water resource system, we discuss the connotation of sustainable water resource system and explore the operating mechanisms of sustainable water resource system, including dynamic, resistance and coordination for three mechanisms, which control the evolution of sustainable water resource system. Then, after the establishment of the indicator system of sustainable water resource system evaluation, the regional sustainable water resource system evaluation model is set up by using set pair analysis theory. The evaluation results are obtained by calculating connection degree of each indicator. Finally, taking Shanghai as an example, it analyzes the water resource sustainability in Shanghai by using this model. The calculating results indicate that the situation of sustainable water resources system was better, which is in accordance with the actual situation in Shanghai.

Water Resources Vulnerability

Climate change has tremendously changed the hydrological processes with global warming. There are many uncertainties in assessing water resources vulnerability. To assess the water resources vulnerability rationally under climate change, an improved set pair analysis model is established, in which set pair analysis theory is introduced and the weights are determined by the analytic hierarchy process method. The index systems and criteria of water resources vulnerability assessment in terms of water cycle, socio-economy, and ecological environment are established based on the analysis of sensibility and adaptability. Improved set pair analysis model is used to assess water resource vulnerability in Ningxia with twelve indexes under four kinds of future climate scenarios. Certain and uncertain information quantity of water resource vulnerability is calculated by connection numbers in the improved set pair analysis model. Results show that Ningxia is higher vulnerability under climate change scenarios. Improved set pair analysis model can fully take advantage of certain and uncertain knowledge, subjective and objective information compared with fuzzy assessment model and artificial neural network model. The improved set pair analysis is an extension to the vulnerability assessment model of water resources system.
