摘 要：
总结了1985年11月至1986年7月太平湖水库水质的理化特性，结果表明：太平湖水库水质良好，透明度高平均为321cm；pH值平均为7.4；水中溶解氧丰富；总离子量较低；水质属重碳酸盐类钙组Ⅰ型水(CCaⅠ)。水中主要生物营养元素氮含量较高，总氮平均为1.49mg/L，磷含量较低，总磷平均为0.012mg/L。氮、磷比为124.2∶1，表明磷是该水体生物生产力的限制性营养元素。水中多数理化组分有明显的季节变化，多数理化组分在平面和垂直分布上也有差异，但差异不显著。

摘 要：
This paper summarizes water physicochemical chara cteristics from November,1985 to July,1986 in Taiping Reservoir.The results show e d:Taiping Reservoir has good water quality. Secchi transparency was high,pH val ue was 7.4,dissolved oxygen was rich,hardness was lower,total ionic amounts was l ower.The water type belongs to The contents of TH in water was 1.49mg/L.The cont ents of TP were 0.012mg/L.The N/P ratio was 124.2∶1,which means that phosphorus was the major nutrient limiting biological productivity. There were marked seas onal changes inmost physicochemical components in the water.The differences of m ost physicochemical components were inconspicuous in horizontal and vertical di stributions.
