以潇河典型污水灌区为研究对象，对选定区域土壤进行剖面取样、样品分析，并分析了灌溉用水中氮素的含量，以确定灌溉用水对于土壤中铵态氮及硝态氮含量分布的影响。结果表明：潇河灌区土壤中的铵态氮与硝态氮含量在垂向分布上具有规律性；灌溉用水作为土壤氮素来源之一对土壤氮素在垂直方向上的分布规律有一定的影响；只要对污水进行有效处理，污水中的氮素将不会对地表水及地下水造成较大影响，完全可以取代地下水及河水用于农业灌溉，缓解灌溉水资源的危机。

This paper took the typical sewage irrigated area which is in Xiaohe irrigated area as the research object. Profile sampling and sample a-nalysis was carried out on soil of selected areas and analyzed the nitrogen content of irrigation water to determine the influence of irrigation water to distribution of ammonium nitrogen and nitrate nitrogen content in soil. The results show that the ammonium nitrogen and nitrate nitrogen content in soil of Xiaohe irrigation area have regularity on vertical distribution. Irrigation water as a source of soil nitrogen have effects on vertical regularities of distribution to soil nitrogen;If only takes effective treatment to wastewater sewage,nitrogen in sewage will not cause great influence to the surface water and underground water. It can completely replace groundwater and river water used for agricultural irrigation and will greatly ease the crisis of the irrigation water resources.
