Evaluation on the Regional Water Security Based on Virtual Water Theory and Fuzzy-AHP Model
摘要
Abstract
From the aspect of social-economic security, food security, and water resource and ecological security, the evaluation index system of regional water security was established, which was composed of 13 indexes with some indicators quantified by virtual water theory. The Fuzzy-AHP method was applied to evaluate the regional water security situation of Zhengzhou City from 1998 to 2005, besides the year of 2015 and 2020 in the 25%, 50% and 75% hydrology years. Results showed that the indexes of water footprint per capita, water resources per capita, food security index, dependency ratio, degree of food self-sufficiency and water stress weights accounted for 79% of the total weight, so the water safety conditions was determined by the six aspects. The integrated security situation and the security situation of socio-economic layer, and the security situation of the safety of food layer were all safe, while the resources-ecological security layer was unsafe, suggesting that the security socio-economic and the safety of food were achieved at the expense of regional resources and ecological security. Therefore, the regional water security situation in Zhengzhou City was in the safe security with irrational structure.关键词
