摘要
根据多年的监测数据,并结合跟踪监测,分析影响滇池水体pH值变化的因素。结果表明,当水体Chl.a浓度低于约1500μg/L,水体pH值变化与DO和Chl.a呈现显著的正相关关系,但当水体叶绿素a超过这个浓度时,DO和pH值也将会下降。表明水体pH值变化与水体中植物的光合作用强度呈现显著正相关关系。
Influenced by geology,geographical environment and climate,the problem of excessive pH value in Yunnan plateau lakes is prominent.In this study,combined with years of tracking monitoring data,the factors affecting the change of pH value in Dianchi Lake have been analyzed.When the concentration of chl.a is less than 1500μg/L,there is a significant positive correlation between the pH value and Chl.a.When concentration of chl.a exceeds 1500μg/L,DO and pH will also decrease.The results showed that there was a significant positive correlation between the water pH value and the photosynthetic intensity of plants in the water.
