重庆迎龙湖水库富营养化研究

Study on Water Eutrophication in Yinglonghu Reservoir

以水质监测资料为基础,选择综合营养状态指数法对重庆市迎龙湖水库成库后水质的营养状况进行了综合评价.结果表明:迎龙湖水库营养状态指数逐年增加,从中营养逐步向富营养发展.迎龙湖水库具备发生富营养化的水文、地理、气象和水质等基本条件,防治富营养化的关键在于控制营养盐特别是磷元素的输入.

The basic situation of the Yinglonghu Reservoir is analyzed and the method of water quality monitoring is introduced. Based on the monitoring data, the TCI-ACP method is adopted to evaluate water quality comprehensively. The results show eutrophic state of Yinglonghu Reservoir has trended to ingravescence, and it is in mesotrophic state now and tends to be eutrophic. Hydrographic,geological,meteorological and water qualitative conditions of Yinglonghu Reservoir are meet to water eutrophication to occur. And the key measure to control water eutrophication is to cut down the amount of nutrient elements input, especially the amount of phosphorus elements input.
