摘 要：
于2012年对鸭河口水库粪大肠菌群、叶绿素a和水质理化指标进行监测,按水样采集标准方法于水库出口处采样,采用营养状态指数法对中线水源区进行营养状态评价。结果表明,鸭河口水库叶绿素a的营养状态指数为38.70,水质综合营养状态指数为43.1;单项理化监测指标中除总氮为Ⅲ类水质标准外,其他监测指标均符合Ⅰ类水质标准;丰水期、枯水期和平水期3个水期水质基本相近。综合评价,鸭河口水库水质稳定,处于中营养状态。

摘 要：
Fecal coliform, chlorophyll a content and physicochemical indexes were monitored at the outlet of Yahekou Reservoir in 2012. Water samples were collected by standard methods. The method of trophic status index was used to evaluate the trophic status of the water quality. The results showed the trophic status index of chlorophyll a was 38.70 and the nutritional index of water was 43.1. The physicochemical indexes excepted total nitrogen are under the standard ofⅠtype water, and the total nitrogen was under the standard of Ⅲ type water. The water quality of wet water period, common water period and low water period was similar. Comprehensive results showed that water trophic state of this water area was stable and could be regarded as mesotrophy.
