摘要
The aquaculture pond water quality was taken as research objects,based on the general analysis of factors influencing the pond water quality,the system of index estimation and assessment standard were established after sorting by importance of the factors by means of Delphi and expert investigation.In this study,index weight was confirmed according to the importance of the factors and relative membership grade of the measured values,thus and the fuzzy comprehensive evaluation model of aquaculture pond water quality was constructed,and the fuzzy comprehensive evaluation system of freshwater aquaculture pond water quality was designed and implemented.The application of this system in the assessment of aquaculture pond water quality by a company had achieved better result.
以池塘淡水养殖水质为研究对象,在综合分析池塘水质各影响因子的基础上,通过专家问卷调查法和德尔裴法对水质因子的重要程度进行了排序,建立了池塘水质评价指标体系和评价标准,用重要程度法和实测值相对隶属度法确定了指标权重,建立了池塘水质模糊综合评价模型,并设计和实现了淡水池塘养殖水质模糊综合评价系统。将该系统应用于某企业淡水养殖池塘水质的评价,取得了较好效果。
