摘要

The water quality of main rivers in Binzhou City,Shandong Province was comprehensively evaluated based on RAGA-PPCE model.Six main factors such as ammonia nitrogen(NH3-N),total phosphorus(TP),total nitrogen(TN),chemical oxygen demand(COD),dissolved oxygen(DO)and pH were used to establish the evaluation and classification standards of water quality.The results showthat the evaluation results of water quality by RAGA-PPCE model and the fuzzy comprehensive evaluation method are basically the same.The evaluation results of RAGA-PPCE model are objective and reasonable and can be applied to the comprehensive evaluation of water quality.
