摘要
为了研究洱海水环境现状,应用2021年1月—2022年4月大理洱海金河国家水质自动监测站水质监测资料及洱海水质监测数据,采用综合评价法、单因子评价法分析了洱海金河水质现状及运动变化趋势,结果显示,4个月达到Ⅱ类水质标准,12个月达到Ⅲ类标准,自2016年洱海实施抢救模式以来,T-P、T-N得到有效遏制。
To study the current status of the water quality of Erhai Lake,the monitoring information of the Jinhe National Automatic Water Quality Monitoring Station and the water quality monitoring data of Erhai Lake from January 2021 to April 2022 were applied and analyzed.The trend of the changes was examined using the comprehensive evaluation method and the single-factor evaluation method.The results showed that the water quality reached the standard of Class II in 4 months and Class III in 12 months.TP and TN have been effectively curbed since the implementation of the salvage mode was complemented in the Erhai Lake basin in 2016.
