| 摘 要： | 根据现场取样分析,对张集水源地裂隙岩溶水水化学特征进行了总结和分区,分析了其影响因素,提出了相应的环境保护措施.结果表明,裂隙岩溶水水化学类型一般为HCO3-Ca@Mg型及HCO3-Ca型,个别点出现HCO3@SO4-Ca型水,总体水质较好,存在局部污染现象;水源地裂隙岩溶水水质受含水层岩性和降水、地表水以及孔隙水越流等补给的影响,在制定水源地保护方案时应予考虑.

| Abstract: | For sustainable use and protection of Zhangji well field,based on experimental data of the samples,the characteristics of chemical components of fracture-karst groundwater are analyzed,summed and classified,with the causes analyzed.A primary suggestion is put forward for the well field.The results show that most types of chemical components of fracture-karst groundwater are of HCO\-3-Ca·Mg or HCO\-3-Ca types,except HCO\-3·SO\-4-Ca type in one or two points;as a whole,the quality of fracture-karst groundwater is good for drinking except the polluted points;the factors affecting the quality of fracture-karst groundwater include the components of the rock of the aquifer and the recharge of precipitation,surface water and pore water.These factors must be considered in formulating protection plans for resources in Zhangji well field. |
