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。
The physical and chemical properties of Taipinghu reservoir from November 1985 to July 1986 are summarized. The results show that the water quality of Taipinghu reservoir is good, the average transparency is 321cm, the average pH is 7.4, the dissolved oxygen in water is abundant, the total amount of ions is low ; Water quality is bicarbonate calcium group Ⅰ water (CCa Ⅰ). The nitrogen content of main biological nutrient elements in water is higher, the average total nitrogen is 1.49mg / L, the phosphorus content is lower, the average phosphorus is 0.012mg / L. The ratio of nitrogen to phosphorus was 124.2:1, indicating that phosphorus is a limiting nutrient for the biological productivity of this water body. Most of the physical and chemical components in water have obvious seasonal changes, and most of the physical and chemical components also have differences in horizontal distribution and vertical distribution, but the differences are not significant.
