| 摘 要： | 基于Mann-Kendall趋势检验法和小波分析法,研究了汾河河津段2004—2013年高锰酸盐指数、氨氮、溶解氧含量时间序列的变化趋势和突变特性。结果表明:高锰酸盐指数和氨氮含量有显著下降趋势,溶解氧含量有显著上升趋势。高锰酸盐指数和氨氮含量在1、2月较大,8、9月较小;溶解氧含量在1、2月较大,6、7月较小。高锰酸盐指数含量在2004—2009年差异较大;氨氮含量在2004—2013年差异均较大;溶解氧含量在2010—2013年差异较大。

| Abstract: | The time series trends and mutation features of CODMn, NH3-N and DO in Hejin section of Fenhe River were analyzed via Mann-Kendall method and Wavelet Analysis. The results indicated that:The concentrations of CODMn and NH3-N had a significant downward trend and the concentration of DO had a significant upward trend. The concentrations of CODMn and NH3-N were large in January and February and were low in August and September; the concentration of DO was large in January and February and was low in June and July. The concentration of CODMn had significant differences between 2004 and 2009; there were differences on the concentration of NH3-N between 2004 and 2013; the concentration of DO had significant differences between 2010 and 2013. |
