In this paper, a fuzzy multi-attribute decision analysis approach (FMADAA)
was developed for supporting the evaluation of water resources security in
nine provinces within the Yellow River basin. A numerical approximation
system and a modified left–right scoring approach were adopted to cope with
the uncertainties in the acquired information. Also, four conventional
multi-attribute decision analysis (MADA) methods were implemented in the
evaluation model for impact evaluation, including simple weighted addition
(SWA), weighted product (WP), cooperative game theory (CGT) and technique for
order preference by similarity to ideal solution (TOPSIS). Moreover, several
aggregation methods including average ranking procedure, Borda and Copeland
methods were used to integrate the ranking results, helping rank the water
resources security in those nine provinces as well as improving reliability
of evaluation results. The ranking results showed that the water resources
security of the entire basin was in critical condition, including the
insecurity and absolute insecurity states, especially in Shanxi, Inner
Mongolia and Ningxia provinces in which water resources were lower than the
average quantity in China. Hence, the improvement of water eco-environment
statuses in the above-mentioned provinces should be prioritized in the future
planning of the Yellow River basin.
