模糊综合评价模型在水库水质分析中的应用OACHSSCD

Reasonable and objective evaluation on reservoir water quality is of great significance for water resource utilization and protection.The fuzzy comprehensive evaluation method was applied to the water quality evaluation of Biliuhe reservoir,the weight of indicators was determined by clustering weight method,and the evaluation results were compared with those of exceeding-standard method,variation coefficient method and entropy weight method.Evaluation results show that the reservoir water quality of all monitoring points meets the national surface water Class Ⅲ standard when using clustering weight method,with total nitrogen exceeding the standard severely.The evaluation method objectively reflects the water quality characteristics of Biliuhe reservoir and can provide a reference for reservoir water quality evaluation.
