Description
Summary:The complex urban water circulation system is developing in a more severe and complicated direction, and the phenomenon of urban water metabolism imbalance and water metabolism crisis become more and more obvious. The PSR framework model is introduced to construct the urban water metabolism safety evaluation index, and the entropy weight method is used to determine the weight of the corresponding evaluation index and the calculation of the safety index, at the same time, taking Tianjin city as an example. Research results show that, the evolution process of water metabolism in Tianjin showed a trend of development during the evaluation period, that is, obviously improved in the early stage, stable in the medium term, and decreased in the later period, the empirical data show that the evaluation results are reasonable.
