摘要
选择佛山市为研究区域,通过4年定点观测的129次降雨数据,分析了雨水pH、雨量以及雨强之间的相关性,讨论了酸雨的季节性分布规律,结果表明:1)月平均雨水pH与月份之间呈线性关系,5~10月的雨水pH明显高于其他月份,冬春季节雨水pH平均值不仅明显小于夏秋季节,而且酸雨比例、重度酸雨比例明显高于夏秋季节。2)129次降雨量与雨水pH呈不显著负相关关系,但随酸雨程度增加,降雨量对雨水pH的影响程度增加,重度酸雨的降雨量与雨水pH之间呈显著负相关关系。3)雨强与雨水pH呈显著负相关关系,暴雨使重度酸雨出现的比例与小雨比较增加了22.89%。4)降雨间隔期增长使酸雨发生和程度呈加重的趋势。
Taking Foshan city as the research area,the correlation among rain pH,rainfall and rainfall intensity was analyzed through 129 rainfall data observed in 4 years,and the seasonal distribution of acid rain was discussed.The results showed that:1)the monthly average rain pH was linear with the month.The rain pH from May to October was significantly higher than that in other months,and the average rain pH in winter and spring was not only significantly lower than that in summer and autumn.in addition,the proportion of acid rain and severe acid rain was significantly higher than that in summer and autumn.2)There was no significant negative correlation between 129 times of rainfall and rain pH,but with the increase of acid rain degree,the influence of rainfall on rain pH increased,and there was a significant negative correlation between heavy acid rain rainfall and rain pH.3)There was a significant negative correlation between rain intensity and rain pH.The proportion of heavy acid rain increased by 22.89%compared with light rain.4)The increase of rainfall interval aggravates the occurrence and degree of acid rain.
