摘　　要：选取较为敏感、变化幅度较大的水质评价因子,运用对比的方式,研究降雨量与这些评价因子之间的变化规律,评价海源寺114泉所属水文地质单元内地表水与地下水之间的联系性,分析污染因子的来源,探讨降雨对泉水水质的影响。结果表明:海源寺114泉所属水文地质单元内地表水与地下水联系紧密,降雨对浑浊度影响迅速,呈正比例关系,但浑浊度的变化滞后约1天。雨季初期,降雨对锰离子及氨氮的影响呈正比例关系,中后期持续降雨情况下,锰离子及氨氮呈持续下降趋势,特大暴雨情况下,锰离子及氨氮浓度呈直线下降趋势,锰离子与氨氮变化曲线基本一致,可能为同一污染物。To assess the connection between surface water and groundwater in the hydrogeological unit where No.114 Spring of Haiyuan Temple is located,this paper selects sensitive and highly variable water quality evaluation factors and studies the variation patterns between rainfall and these evaluation factors by using a comparative approach.Further exploration is also carried out of the source of pollution factors and their concentration changes with rainfall.The results show that the surface water and groundwater in the hydrogeological unit are closely linked.Rainfall has an immediate impact on turbidity,showing a direct proportional relationship,but the change in turbidity lags by about one day.At the beginning of the rainy season,rainfall has a direct proportional relationship with manganese ions and ammonia nitrogen.During continuous rainfall in the middle and later stages,manganese ions and ammonia nitrogen show a continuous downward trend.Under the influence of extremely heavy rainfall,the concentrations of manganese ions and ammonia nitrogen show a linear downward trend.The variation curves of manganese ions and ammonia nitrogen are basically the same,suggesting they are caused by the same pollutant(s).
