| 中文摘要: |
| 以淮河流域江苏平原区浅层地下水为研究对象，通过对当地影响较大的污染源调查采样，分析了该地区所采602组水样的无机和有机污染状况。研究表明，区内浅层地下水无机污染较严重，基本形成面状污染，地下水超标率高达83.4％，超标率最高为碘化物。有机污染物检出率34.2％，主要包括二氯甲烷、萘和1,2-二氯乙烷等，以点状分布为主。在此基础上阐述了大气降水、污水灌溉、农业施肥以及地下水开采等人类活动对浅层地下水的影响和污染状况。 |
| 英文摘要: |
| Base on the study on shallow groundwater in the Huaihe valley in the plain in Jiangsu province, 602 groups of water sample were investigated and determined for element concentrations and organic pollutants. It suggested that shallow groundwater was extremely contaminated by inorganic pollution in district and thus formed non point source pollution. Unfortunately, the amount of exceed the standard of inorganic, organic pollution is respectively 83.4%（mainly iodid）,34.2%. Organic pollution is consisted of dichloromethane, naphthalene and 1,2 dichloroethane that was derived from point source. Moreover, the paper discussed the influenced that precipitation, sewage irrigation, agricultural fertilizing and groundwater exploitation. |
