摘　　要：通过对松花江哈尔滨段的5个监测站点分析,选用BOD5、CODmn、DO、NH3-N四项主要污染因子,对其2006~2015年的年平均浓度,利用PWQTrend水质分析软件运用季节性肯达尔检验原理进行了水质变化趋势检验,并且运用GM(1,1)模型预测2016~2025年四种主要污染因子的浓度变化.根据水质变化趋势分析和预测结果,可以有针对性的治理流域内的某一因子引起的污染问题.Based on five monitoring stations in Harbin section of Songhua River,the annual average concentration of BOD5,CODmn,DO and NH3-N in 2006-2015 was tested by using seasonal Kendall test principle and PWQ Rend water quality analysis software.GM(1,1)model was used to predict the trend of water quality change.The concentration change of four major pollution factors 2016~2025 years are measured.According to the trend analysis and prediction results of water quality change,the pollution problems caused by a factor in the river basin can be harnessed.
