长江流域某水库pH值与环境因子的相关性研究

Study on the Correlation between pH and Environmental Factors in a Reservoir in the Yangtze River Basin

通过对2013年3月至2014年3月长江流域某水库上游库外及输水区pH值、水温、溶解氧、叶绿素a、总碱度、总硬度的数据进行统计,分析了这两个站点pH值与水质因子的相关关系。根据输水区pH值与水质因子的相关性分析结果,初步探究降低pH值的方法。一是降低水的碳酸盐硬度,控制水中的营养盐;二是建立生物链控藻;三是下游库外合理排水,置换水库水体。

Based on the data of pH value, water temperature, dissolved oxygen, chlorophyll a, total alkalinity and total hardness of the upstream and outside of the reservoir in the Yangtze River Basin from March 2013 to March 2014, the correlation between pH value and water quality factors of these two stations was analyzed. According to the correlation analysis between the pH value and the water quality factor in the water supply area, the method of reducing the pH value is preliminarily explored. The first is to reduce the water＇s carbonate hardness and control the nutrients in the water; the second is to establish the biological chain-controlled algae; and the third is to rationally drain the reservoir outside the reservoir and replace the reservoir water body.
