Multilevel fuzzy comprehensive evaluation for water quality of urban inland river based on the AHP to determine the weights

Xiaoyan Zhang

Abstract


Analytic hierarchy process (AHP) is used to optimize the issue of weights in the traditional fuzzy comprehensive evaluation, and a fuzzy comprehensive evaluation model is constructed based on AHP. The water quality of the urban inland rivers is selected as the research object to introduce the process of multilevel fuzzy comprehensive evaluation for the water quality of urban inland river, which is applied to the water quality evaluation of Baoding Fu River in Baoding City. Evaluation comparison is conducted on the water quality of the selected monitoring sites and the monitoring river reaches during different periods. The results show that the water quality of the monitoring reaches of Fu River is Inferior Class V and the inland river is seriously polluted.
