[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(Cyprinuscarpio)为主养鱼,平均规格71.4g/尾,密度分别为6000、9000、12000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,6000尾/hm2组池塘属Ⅰ类水,9000和12000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9000和12000尾/hm2组池塘的水质没有差异。 [Objective] The entropy weight fuzzy comprehensive evaluation method was used to evaluate the water quality of farmed ponds in order to provide reference for water quality evaluation of pond culture. [Method] The entropy weight fuzzy comprehensive evaluation method was used to evaluate the water quality of three groups of ponds which were dominated by Cyprinus carpio and averaged 71.4g / tail density and 6000, 9000, 12000 tail / hm2 respectively. [Result] According to the surface water environmental quality standard GB3838-2002 of our country, in the breeding process, the pond of 6000 tail / hm2 group belongs to the class Ⅰ water, and the 9000 and 12000 tail / hm2 pond belong to the Ⅴ water. [Conclusion] With the increase of stocking density, the water quality of pond gradually became worse, but from the result of comprehensive evaluation, it can be seen that there was no difference in water quality between 9000 and 12000 tail / hm2 ponds.
