三种不同养殖品种池塘水质变化特征分析及比较

Analysis and comparison of water quality among three ponds with different species farmed

研究了养殖泥鳅、翘嘴红鲌和青虾池塘的水质变化特点,并用VIKOR算法比较了三种养殖品种的池塘水环境质量。结果表明:三种养殖品种池塘的水质变化特点基本相同,但是三种池塘中,青虾养殖池塘水质最优,泥鳅池塘次之,翘嘴红鲌池塘最差。

The variation of water quality was analysed in ponds where loach,erythroculter ilishaeformis and freshwater shrimp were farmed respectively,and the water quality of three ponds was compared with the VIKOR algorithm. The results indicated that the variation of water quality of three ponds was similar,but the water quality of the pond where freshwater shrimp farmed was the best,where loach farmed was the second,and the quality of the pond where erythroculter ilishaeformis farmed was the worst among three ponds.
