摘　　要：氮是滦河附近地下水的主要污染指标之一,有NH3-N、NO2-N、NO3-N三种存在形式,主要来源于大气、土壤非饱和带和地表水。通过钻孔地下水样分析获得了滦河地下水中的离子含量,分析了滦河三个断面附近地下水中的氮含量。基于地下水污染敏感性模型DRASTIC,提出了DRASTMICK模型,该模型主要增加了河床底积物厚度和渗透性等指标,敏感性分析结果显示,滦河研究区域附近地下水从上游至下游抗污染能力逐渐增强。Nitrogen is one of the groundwater key pollution indicators of Luanhe River. It has three main forms including NH3 - N, NO2 - N, NO3 - N which mainly come from the atmosphere, the soil in the unsaturated zone and surface water. Through the analysis of groundwater samples, this paper obtained the ions content of groundwater and analyzed the nitrogen content of groundwater near three sections of the Luanhe River. Based on the groundwater pollution sensitivity model DRASTIC, this paper put forward DRASTMICK model which adds indictors of river sediment thickness and permeability. The sensitivity analysis shows that the antipollution capacity of groundwater is gradually increased from upstream to downstream in the study area.
