北庙水库pH值升高原因分析
Cause Analysis of pH Rise in Beimiao Reservoir
摘要: 为探索北庙水库的pH值在2017年之后呈现明显上升趋势的原因，文章对2015年1月至2022年7月北庙水库的pH值与水温、溶解氧、叶绿素a、硝酸盐氮和五日生化需氧量等潜在影响指标之间的对应关系和指标之间的相关性进行了分析，同时对相关影响机制进行了探讨。结果表明，除浮游植物繁殖导致北庙水库pH值升高外，近年来在春季至夏末时段，反硝化作用的明显增强是导致北庙水库pH值出现异常升高的一个重要原因，而浮游植物的繁殖和反硝化作用的增强均反映出流域内农业面源污染对北庙水库水质的影响。
Abstract: To explore the reasons why the pH value of Beimiao Reservoir showed a significant rising trend after 2017, the corresponding relationship and correlation between pH value and the potential indicators such as water temperature, dissolved oxygen, chlorophyll a, nitrate nitrogen and five days’ biochemical oxygen demand (BOD5) in Beimiao Reservoir from January 2015 to July 2022 were analyzed in this paper, and the relevant influencing mechanisms were also discussed. The results showed that in addition to the growth of phytoplankton, the evident enhancement of denitrification from spring to late summer in recent years was an important cause of the abnormal increase in the pH value of Beimiao Reservoir, and both the growth of phytoplankton and the enhancement of denitrification reflected the influence of agricultural non-point source pollution on the water quality of Beimiao Reservoir.
