摘　　要：河流沉积层中有机氮的矿化对地下水环境的影响很大,影响矿化的因素很多,主要包括环境条件、黏土含量等,通过室内设计的几套土柱实验,详细进行影响矿化作用的因素分析.结果表明:渗滤系统中有机质含量越丰富,系统中有机氮矿化出来的氮量越多.Ammonification of organic nitrogen in river sediment has great effect on groundwater environment. There are many factors influencing ammonification, which include environmental condition, organic content, thickness of sediments, temperature and so on. With several self - designed indoor soil column experiments, the factors influencing the mineralization are analyzed in detail. It can be concluded that the more the organic content is, the more nitrogen of mineralization is. It provide theory element for understanding high concentration ammonium nitrogen of groundwater environment.
