Abstract: Analysis of variance and cluster analysis were made on several parameters of water quality for two representative water bodies (Caogang Lake, Pandian reed marshes) in the Fengqiu Experimental District. The results showed that water quality was typical in Northern China and was usually influenced seasonality. There were no apparent differences in water quality between the two water bodies. The pH value was relatively high (annual means, 8.0-9.0) and the water was weakly alkaline. The hardness was high (17 54-20.63) and tended to increase over the years. The waters were rich in ions, with high alkality (4.57-5.20me/L) and concentrations of nutrient salts (eg, TN:1.31-2.08mg/L, TP:0.100-0.135mg/L). In conclusion, the water bodies have good water quality and high potential for fishery development. Phosphorous may be the major limited nutrient for aquatic productivity.
