Abstract:
Regional water security is the basis of protection of the regional sustainable development. Based on the characteristics of water resources and specific situation of Anhui Province, a comprehensive evaluation index system of water security was developed, and AHP was used to evaluate the water security situation of Anhui Province from 2005 to 2010. The results suggested that the water security situation is between "unsafe" and "basically safe" in Anhui Province from 2005 to 2010 and thus water security situation is not optimistic. This conclusion was in coincidence with that determined by the set pair analysis, which indicated that AHP is feasible and reliable for water security evaluation. Finally, from the perspective of improving water security, some recommendations were proposed to promote savings, increase the utilization efficiency of water resources, and improve water quality.
