摘要
氨氮是评价水体环境质量的基础指标,根据水质氨氮的监测数据,利用2016-2019年黄河及其支流兰州段监测点位监测分析氨氮浓度的时间变化趋势,对近几年黄河兰州段水质氨氮浓度变化进行分析评价,为更好的保护黄河流域提供一些理论依据。
mmonia nitrogen is a basic indicator for evaluating the environmental quality of water bodies.Based on the monitoring data of water quality ammonia nitrogen,the monitoring points of the Yellow River and its tributaries in Lanzhou in 2016-2019 are used to analyze the time change trend of ammonia nitrogen concentration.Analysis and evaluation of the changes will provide some theoretical basis for better protection of the Yellow River Basin.
