Comprehensive Evaluation of Water Resources Carrying Capacity in Qingdao Based on VIKOR-coupling Coordination Degree Model
Based on the VIKOR model and the coupling coordination degree model,the water resources carrying capacity level of Qingdao from 2015 to 2021 was evaluated,and the correlation development between the water resources subsystem and the economic and social subsystem was analyzed.The evaluation of 12 indicators was constructed,and the index data was standardized.The analytic hierarchy process is used to obtain the subjective weight,the coefficient of variation method is used to obtain the objective weight,and the combination weight is given.The VIKOR model is used to calculate the evaluation value,and the coupling coordination degree model is used to judge the coordination degree of the two subsystems.The load force of water resources in Qingdao City has increased as a whole,but there are fluctuations.From 2015 to 2021,the coordination degree of water resources and economic and social systems gradually increased,and the coordination ability of water resources in 2017 and 2019 was relatively low.The results of water resources management in Qingdao are obvious,but it is still necessary to strengthen the monitoring and management of water resources,promote the good development of the allocation of the two subsystems,improve the efficiency of water resources and utilization,and ensure the sustainable use of water resources.
