太湖水源地pH变化与水生生物生长的关系

The relationship between pH change of Taihu and growth of aquatic plant

太湖苏州水域集中式饮用水水源地pH指标在Ⅲ类水标准线值附近波动,成为水源地水质全面稳定提标的制约因素之一。为进一步确保太湖水源地水质安全,提升水源地水质,对出现pH值波动现象比较突出的"金墅港"水源地pH值季节变化规律,pH值变化规律与水生生物生长的关系进行分析,探究太湖水生生物种群及生物量的控制方案。通过分析,金墅港pH值与藻密度呈现显著相关关系,金墅港水源地pH值随藻类生长旺盛而升高,pH值偏高的应对办法主要是科学管护水生植物与藻类。

The pH fluctuations of suzhou Taihu centralized drinking water source become one of the restricting factors of water quality stablization.In order to ensure the water quality and safety of Taihu drinking water source and improve the water quality of drinking water,the seasonal change of the pH value of the"Jinshu Port"water source and the relationship between the change of pH value with the growth of aquatic plant were analyzed to explore the control scheme of the aquatic plant population and biomass in Taihu.According to the analysis,there was a significant correlation between the pH value of Jinshu Port and the density of algae.The pH value of the water source of Jinshu Port increased with the vigorous growth of algae.The measures for controlling high pH value were management of aquatic plants and algae.
