摘　　要：合肥市环城水系是以再生水为唯一补水水源的城市景观水体,选择环城水系中具有代表性的银河水体,对河道水体中的磷、氮、溶解氧和pH值的垂直分布及变化规律进行了研究。结果表明,沿水体的深度方向,总磷、氨氮、正磷酸盐浓度逐渐增高,pH值和溶解氧浓度则逐渐降低。溶解氧和pH值可间接反映藻类的生长情况和密度,可作为水华暴发的简便预警指标。The city-circling water system in Hefei City is landscape water body supplemented only by reclaimed water. The representative river, Yinhe River in the city-circling water system was chosen, and the vertical distribution and variation rule of phosphorus, nitrogen, DO and pH in it were investigated. The results show that the concentrations of TP, NH3 - N and PO4^3- - P increase gradually with the depth increasing, while pH and DO decrease. The pH value and DO can indirectly reflect the growth and density of the algae, and may be used as an alarm signal of water bloom.
