本文根据1987年2月至1988年2月的调查资料,讨论了珠江河口水体pH、碱度和比碱度的变化规律及它们与盐度的关系。结果表明,从虎门外至桂山岛的珠江口主水道上,pH随盐度增加而增加。pH与盐度的相关性最好,均在99.9％的置信水平上显著;pH与碱度的相关性次之。珠江河口水的碱度是保守的;在从虎门外至桂山岛的珠江口主水道上,比碱度与氯度是密切的负相关。
Based on the survey data from February 1987 to February 1988, the paper discussed the variation law of pH, alkalinity and specific alkalinity in the Pearl River Estuary and their relationship with salinity. The results showed that the pH of the Pearl River Estuary from Humen to Guishan Island increased with the increase of salinity. The correlation between pH and salinity was the best, all of which were significant at the confidence level of 99.9%. The correlation between pH and alkalinity was second. The alkalinity of Pearl River Estuary water is conservative. On the Pearl River Estuary main waterway from Humen to Guishan Island, the alkalinity and chlorinity are closely negatively correlated.
