• 摘要：本研究以环境水文地球化学理论为基础并采用数理统计的方法,对研究区地下水样和土样的分析数据进行了处理。通过浸滤模拟试验、红外光谱和差热分析等实验手段,对京杭大运河(杭州段)两侧浅层地下水中铁、锰含量偏高的成因进行了探讨。结果表明,该区地下水中铁、锰主要来自含水粘性土层,本区还原的介质环境及特有的地质条件对铁、锰含量偏高有直接影响。

• Abstract：Ground water and soil samples were collected from bank sides along the Hangzhou reach of the Grand Canal and ajnalyzed by IR spectrum and differential thermal analysis. The experimental results and hy-drogeological investigation revealed that the higher contents of iron and manganese in ground water from unconfined aquifer are caused by the release of the elements from the heavy soils of the area as well as the anaerobic condition of the environment.

• Key words：iron  manganese  ground water.
