摘要

[Objective] The aim was to study the construction and application of combined evaluation model of regional water quality plan.[Method] By dint of layer analysis,subjective and objective model of entropy evaluation,the water quality plan in Jinghe was evaluated.Combined evaluation model based on information entropy were constructed,and considering the single model evaluation result,the optimal water quality plan was selected.[Result] The combination weight result suggested that COD amount was the most essential indicator in water quality plan and embodied the importance of water environment protection,which met basic objective of environment protection and social,economic effects.Combined evaluation indicated that in the sixteen plans,plan 16 was of highest comprehensive evaluation value,and can be considered as optimum water quality plan.[Conclusion] Combined evaluation model can effectively list the advantages of each evaluation model and improve the dependability of water quality plan,and provided a new research idea for the optimal evaluation of water pollution control plan.
