Comprehensive evaluation of water resources security in the Yellow River basin based on a fuzzy multi-attribute decision analysis approach

摘要

In this paper, a fuzzy multi-attribute decision anal- ysis 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 modi?ed left–right scoring approach were adopted to cope with the uncertainties in the acquired in-formation. Also, four conventional multi-attribute decision analysis (MADA) methods were implemented in the evalua-tion model for impact evaluation, including simple weighted addition (SWA), weighted product (WP), cooperative game theory (CGT) and technique for order preference by simi-larity to ideal solution (TOPSIS). Moreover, several aggre-gation methods including average ranking procedure, Borda and Copeland methods were used to integrate the ranking re-sults, helping rank the water resources security in those nine provinces as well as improving reliability of evaluation re-sults. The ranking results showed that the water resources security of the entire basin was in critical condition, includ-ing the insecurity and absolute insecurity states, especially in Shanxi, Inner Mongolia and Ningxia provinces in which wa-ter 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.
