Application of Entropy Weight Method and Philo Model Coupling in Evaluation of Water Resources Carrying Capacity——Taking Hefei City as an example

摘要

Since the reform and opening up, with the rapid development of economy and society, China's water resources are facing severe challenges. However, there is no recognized best method for the evaluation of water resources carrying capacity. The evaluation process is either subjective and random. Either the researcher relies too much on the inherent information of the sample and ignores the subjective initiative. The results of both evaluations are not objective and fair. The entropy weight method is used to determine the weight of sample index, and the water resources carrying capacity is comprehensively evaluated through the coupling of the Philo model. Taking Hefei City as an example, the evaluation results are scientific, reasonable and authentic, which can provide reference for the comprehensive evaluation of water resources carrying capacity of related cities.
