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。
Based on the comprehensive analysis of various influencing factors of pond water quality, the importance of water quality factors was ranked by the expert questionnaire method and Delphi method, and the evaluation index system and evaluation standard of pond water quality were established , The index weights were determined by the degree of importance method and the relative membership degree of the measured values, a fuzzy comprehensive evaluation model of pond water quality was established, and a fuzzy comprehensive evaluation system of freshwater pond culture quality was designed and implemented. The system is applied to the evaluation of freshwater aquaculture pond water quality of an enterprise, and has achieved good results.
