                    摘要：为了解山美水库总氮污染特征，初步分析其污染成因，对山美水库“十三五”期间 (2016-
                    2020年)总氮年度监测结果、月度监测结果、进出口浓度差异进行分析，并将总氮月均监测结果与

                    溶解氧、氨氮、BOD等监测指标进行相关分析。结果表明：（1）2016-2020年总氮年均值浓度范围
                    为 2.07~2.68mg/L，进口浓度范围为 2.11~2.75mg/L，出口浓度范围为 2.02~2.61mg/L，进口浓度略
                    高于出口浓度，均低于ⅴ类标准，年均浓度除了 2018 年出现了明显的升高，其它年份变化不明

                    显，总氮污染较为严峻的现象没有出现明显的改变。（2）丰水期(3-9月)山美水库的总氮污染较为

                    相关系数均低于0.3，属不相关；与氟化物、叶绿素a、总磷相关系数分别为0.48、0.39、0.36，均属低
                    度相关；与氨氮、高锰酸盐指数相关系数分别为0.56、0.51，均属中度相关。

              differences of total nitrogen in the 13th Five Year Plan period (2016-2020) of Shanmei reservoir were analyzed. And
              the monthly monitoring results of total nitrogen were analyzed with the monitoring indexes of dissolved oxygen, ammo⁃
