Evaluation of Construction Effect of River and Lake Chief System Based on Quaternionic Linkage Number Set-pair Analysis
In order to scientifically evaluate the effect of the construction of the river and lake chief system,20 indica-tors were selected to build an indicator system from aspects of water resources management,waterside shoreline manage-ment,water project construction and management,water pollution prevention and control,water environment manage-ment,law enforcement and organisation and implementation.Sequential relationship method(G1)is chosen to determine the subjective weights.Entropy weight method(EWM)is used to determine the objective weights.The final weights are obtained by combining the subjective and objective weights through the multiplicative synthesis method,so as to construct an evaluation model based on quaternionic linkage number set-pair analysis.The model was used to evaluate the effect of the construction of the river and lake chief system in 14 district cities in Liaoning Province in 2022.The results show that the implementation of the effect of the construction of the river and lake chief length system in Liaoning Province was good on the whole.Dalian,Anshan,Fushun,Yingkou and Chaoyang had the best implementation.Panjin had the lowest overall evaluation rating,with a large gap between it and the other regions.
