摘要
为研究抚仙湖水体总磷(TP)的周年变化,进一步了解水质状况,分析了2018年5月(春季)、8月(夏季)、11月(秋季)、2019年2月(冬季)水体总磷(TP)和部分理化指标的监测数据,采用综合指数法(TLI(∑))进行水质营养状态评价,并分析其变化趋势。结果表明,总磷(TP)是影响抚仙湖水质营养状态变化的主要指标,综合营养指数(TLI(∑))年均值小于30。评价认为,抚仙湖水质处于贫营养状态。
In order to study the annual change of total phosphorus(TP) in the water body of Fuxian Lake and further understand the water quality, May(Spring), August(Summer), November(Autumn), and February 2019(Winter) Monitoring data of total phosphorus(TP) and some physical and chemical indicators of water body, using comprehensive index method(TLI(∑)) to evaluate water nutrition status, and analyze its changing trend.The results show that total phosphorus(TP) is the main indicator that affects the nutritional status of water quality in Fuxian Lake. According to the evaluation, the water quality of Fuxian Lake is in a poor nutrition state.
