摘要
为了了解晋江市浅层地下水中NH_4^+-N、NO_2^--N和NO_3^--N的含量及其分布状况,按国标对NH_4^+-N、NO_2^--N和NO_3^--N进行测试,研究区NH_4^+-N含量处于0~0.16 mg/L;NO_2^--N含量处于0~0.305 mg/L;NO_3^--N含量处于0.23~45.18 mg/L.NH_4^+-N、NO_2^--N含量水平符合《地下水质量标准》三类水质,而NO_3^--N部分区域则超标.进一步借助地统计与GIS技术分析"三氮"的空间分布情况,可以了解整个研究区浅层地下水质量现状,也可为有关部门在今后的保护、评价和分析地下水等提供参考.
In order to know more about the shallow groundwater content with NH4^＋- N,NO2^-- N,NO3^-- N and theirs distribution in Jinjiang,We text the groundwater indexes of NH4^＋- N、NO2^-- N and NO3^-- N according to the national standard,the result show that NH4^＋- N is in 0 - 0. 16 mg / L; NO2^-- N is in 0 - 0. 305 mg / L; NO3^-- N is in 0. 23 - 45. 18 mg / L in the whole area. shallow groundwater content with NH_4^＋- N、NO2^-- N comply with groundwater quality standard,only parts of NO3^-- N exceeds bid. Further with the geostatistical and GIS analysis to spatial distribution situation of the ＂ three nitrogen＂,it can understand the quality status in the study area of shallow groundwater,it can also be used for the protection of the relevant departments,evaluation and analysis of groundwater to provide reference in the future.
