摘　　要：针对滇池存在pH值和蓝藻浓度双高的生态问题,利用自动监测周报数据,分析了2004—2018年滇池最有代表性的观音山断面pH值及其变化趋势,发现在该时段内,pH值超标率普遍较高,极端pH值高达10.4。结合相关文献,分析了高pH值对滇池生态修复中有重要作用的沉水植物、浮游动物和鱼类的限制作用以及对铜绿微囊藻和水华鱼腥藻的潜在促进作用。为更好地保障滇池生态治理成效和促进生态修复进程,建议加强滇池高pH值形成机制研究,加强入湖河流和牛栏江引水工程对滇池高pH值的减缓作用,加强滇池pH值内源污染治理研究和工程建设。In response to the ecological problem of high pH and blue-green algae concentration in Dianchi Lake,using automatic monitoring weekly report data,the pH value and its change trend of the most representative Guanyinshan Section in Dianchi Lake from 2004 to 2018 were analyzed.It was found that during this period,the rate of pH exceeding the standard was generally high,with an extreme pH value as high as 10.38.Combined with relevant literature,the restrictive effect of high pH values on submerged plants,zooplankton,and fish that play an important role in ecological restoration of Dianchi Lake were analyzed,as well as their potential promoting influence on Microcystis aeruginosa and Anabaena flos-aquae.In order to better promote the effectiveness of ecological governance and ecological restoration process in Dianchi Lake,it is recommended to strengthen the research on the mechanism of high pH formation in Dianchi Lake,strengthen the alleviation effect of water diversion projects from rivers entering the lake and Niulan River on high pH in Dianchi Lake,and strengthen the research and engineering construction of endogenous pollution control of pH in Dianchi Lake.
