| 摘 要： | 北京市西南城近郊是本市高硬度水主要分布区，也是北京平原区地下水主要补给区，浅层地下水水质恶化已成为影响本区经济发展的主要因素。本文通过对区内14个长期观测孔11a来水质资料的统计分析，从统计学和水化学角度分析了本区浅层地下水盐污染特征和机理。结果说明，盐污染主要是硬度升高和硝酸盐污染，而在时间和空间分布上的不均匀性，显示出污染源、污染途径及污染机理的复杂性。最主要的污染原因有：独特的水文地质条件，污灌，砂石坑垃圾回填，及区域地下水位下降。 |

| Abstract: | The southwest suburb of Beijing is the main district of high hardness of water, and is the main recharge area of groundwater in Beijing Plain. The deterioration of shallow groundwater quality in the district has become the main factor that affects the suburbs' development. Based on the statistic analysis of groundwater quality about 14 long\|term observation wells during 11 years, this paper discusses groundwater salt pollution feature and mechanism from the point of view of statistics and hydrochemistry. The results indicate that salt pollution is mainly resulted from the rise of water hardness and the NO - 3 pollution. The unevenness of salt pollution in the distribution of time and space indicates the complexity of pollution sources, pollution causes, and polluation mechanism. The main pollution reasons include the species hydrogeologic conditions, sewage irrigation, landfill of municipal refuse, and regional groundwater drawdown. |
