摘 要:[目的]利用熵权模糊综合评价法对养殖池塘水质状况进行评价,以期能对池塘养殖的水质评判提供参考。[方法]利用熵权模糊综合评价法评价以乌克兰鳞鲤(Cyprinus carpio)为主养鱼,平均规格71.4 g/尾,密度分别为6 000、9 000、12 000尾/hm2的3组池塘的水质情况。[结果]根据我国地表水环境质量标准GB3838-2002,在养殖过程中,6 000尾/hm2组池塘属Ⅰ类水,9 000和12 000尾/hm2组池塘属Ⅴ类水。[结论]随着养殖密度的增大,池塘水质逐渐变差,但从综合评价结果也可看出9 000和12 000尾/hm2组池塘的水质没有差异。[Objective] This study was to provide references for the evaluation of water quality in aquaculture ponds by evaluating the pond water quality using fuzzy comprehensive evaluation method based on entropy weight.[Method] The fuzzy comprehensive evaluation method based on entropy weight was used to evaluate the water quality in the ponds with Ukraine scale carp(Cyprinus carpio) as the main cultivated fish.The average size of the fish was 71.4 g/ind,and totally three groups of pond were set with the population density of 6 000,9 000,12 000 ind/hm2.[Result] According to the GB3838-2002 Environmental Quality Standards for Surface Water of China,the water quality of 6 000 ind/hm2 group was Grade I,and the water quality of 9 000 and 12 000 ind/hm2 were Grade V.[Conclusion] With the increasing of feeding density,the pond water quality worsened,however,there was no difference on water quality between 9 000 and 12 000 ind/hm2 groups.
