| 摘 要： | 采用韩江下游近年水质分析资料,应用Mann-Kendall检验方法等,对2006-2012年主要指标的变化特征进行研究.结果表明:韩江中下游水质总体较为良好,部分水质因子如铁、粪大肠菌群、氨氮、总氮等指标存在超标现象,其中铁、粪大肠杆菌群、氨氮且呈现不同程度的下降趋势,总氮则呈现上升趋势;部分指标因子与汛期关联紧密.

| Abstract: | Examining recent water quality analyses of the lower reaches of the Hanjiang River and employing the Mann-Kendall method, this paper studies the 2006-2012 changing pattern of the major factors. The findings indicate that the lower reaches of the Hanjiang River have a generally good water quality, except that some factors such as iron, fecal coliform, ammonia nitrogen and total nitrogen are out of limits. The first three factors show a downtrend of varied extent, whereas the last factor, total nitrogen, displays an uptrend. Some index factors are closely related with the flood season. |
