摘要: 运用主成分分析法对三口池塘水质和沉积物共20个指标的检测结果进行了综合评价。结果表明,在养殖前期水质最差,养殖中期水质最好,养殖后期逐渐下降。

关键词: 滨海型盐碱地池塘, 理化因子, 沉积物, 主成分分析

Abstract: In order to evaluate the quality of pond of coastal saline-alkaline land by principal component analysis(PCA), 20 indicators of water and sediment were detected. The results showed that the cultural water quality was the worst at the early stage, but it turned better at the middle, and it got worse at the last stages of the breeding.

Key words: pond of coastal saline-alkaline land, physical-chemical factors, sediment, principal component analysis (PCA)
