中文摘要：

水体质量对渔业的产量和质量有着显著影响。为使水质评价结果更加准确,采用改进的灰色关联分析法对池塘的水质进行评价。在确定指标权重时,采用序关系分析法,避免了采用超标倍数法在计算权重时因某项参数超标而使各综合指标评价偏高的缺点,充分考虑到养殖专家的实际养殖经验,使各指标权重更科学合理,水质关联值更为精准,从而使水质等级更符合事实。以某渔业养殖场4个池塘的水质监测数据为计算实例,选取pH、透明度、总氮、溶氧、COD 5个指标,运用该模型计算的结果与实际情况更吻合。

英文摘要：

water quality has a significant impact on the yield and quality of fishery.In order to make the water quality assessment results more accurate, the improved grey correlation analysis method was used to evaluate the water quality of the pond.When determining the index weight, the order relation analysis method avoid the shortcomings of the excessive multiples method in the calculation, which make the evaluation of comprehensive index too high because a certain parameter exceeds the standard of evaluation, and this method fully consider the actual experience of aquaculture aquaculture experts, the weight of each index is more scientific and reasonable, the water quality association is more accurate, thereby making the water level more in line with the facts.Taking the water quality monitoring data of four ponds of a fishery farms for example, Five indicators such as pH, transparency, total nitrogen, dissolved oxygen, COD were selected , The result calculated by the model is more consistent with the actual situation.
