Abstract:
Water resources are an important factor for the sustainable development of society and economy, and their security receives more and more attention. In this paper, the variable fuzzy recognition method is applied to assess the water resources security in the water source protection area of Songhua dam, and the binary comparison method is adopted to determine the weights of evaluation indexes. The results show that the water resources in the water source protection area of Songhua dam is in safe condition, which is consistent with the results determined by other methods such as Analytical Hierarchy Process (AHP) and Set Pair Analysis. It is suggested that the variable fuzzy recognition method can be effectively used in the multi-index comprehensive evaluation of water resources security.
