The seasonal variations in the rainfall pH and chemical composition were evident, which may be related to the seasonal variations in precipitation amount in Jinyun Mountain. 缙云山降水pH值和各离子含量存在明显的季节变化特点,总体表现为冬春季污染程度高于夏秋季,这可能与降水量的季节变化有关。
However, the EC values of precipitation exhibited strong seasonal patterns practically identical to that for ion concentrations, consistently with minimal values in summer months, intermediate in spring and fall, and maximal in winter, which appeared highly dependent on rainfall amount. 而降水电导率则表现出与离子浓度相同的明显的季节变化格局,两者月均值均以夏季最低,冬季最高,春秋季居中,这种格局强烈受降雨量的控制。
