| 摘 要： | 目的：分析评价新昌江下游地表水水质变化趋势,为进一步改善水质提供科学依据。方法：采用季节性肯达尔检验法对新昌江下游地表水7年（2004-2010年）氨氮、总磷、溶解氧、高锰酸钾指数和化学需氧量主要污染指标进行水质趋势分析。结果：新昌江下游地表水氨氮、总磷、溶解氧、高锰酸钾指数和化学需氧量到2008年基本达到地表水III类水质标准。溶解氧呈高度显著上升趋势,氨氮、总磷、高锰酸钾指数和化学需氧量呈高度下降趋势。结论：新昌江下游地表水污染状况被控制,水质指标以下降变化为主,总体水质状况基本好转。

| Abstract: | Objective To analyze and evaluate the water quality fluctuation trend of surface water at the downstream of Xinchang River,so as to provide scientific basis for improving the water quality.Methods The water quality trend of NH3-N,TP,CODmn,DO and COD was analyzed with the seasonal Kendall method by using the water quality data of the downstream of Xinchang River in recent years(from2004 to2010).Results The results showed that among the water quality trend,the COD,CODmn,NH3-N and TP showed downtrend significantly.The dissolved oxygen showed uptrend significantly.Water quality in main monitoring data of Xinchang River was the third class generally.Conclusion The water pollution at the downstream of Xinchang has been controlled.The pollutant concentrations has a downward trend generally,showing an improvement trend. |
