【摘要】 以Cl-、矿化度和硬度作为评价因子,研究了海水对老港垃圾填埋场地区地下水的影响。结果表明:该地区地下水绝大部分属Cl--Na+型、咸水和极硬水;地下水越深,海水混入比例越大,但地下水距海岸线远近与海水影响程度的相关性不明显;历年地下水监测数据说明此处无海水入侵态势或洗盐淡化趋势;降水、潮汐等因素会引起地下水Cl-含量、矿化度和硬度的波动,反映了海水的影响。更多还原

【Abstract】 Using mineralization degree and hardness as evaluation factorst. The effect of seawater on groundwater of Laogang Waste Landfill site area was studied.The result showed that most parts of groundwater in the area are types of Cl--Na+,salt water and hardest water;the deeper of groundwater, the higher of mixing seawater rate, but the relativity between distance from groundwater to beachline and seawater effect extent is not obvious.Over the years monitoring data of groundwater shows that there are not seawater invading or salt-leaching desalination trends.The factors of rainwater and tide can make Cl-content, mineralization degree and hardness of groundwater change, which reflects influence of groundwater.更多还原
