沙头角湾海水污染物的时空分布特征研究

Spatial and temporal distribution of seawater pollutants in Shatou Bay

利用2016年11月现场调查的数据和2007年~2016年的监测数据为基础,分析了沙头角湾海水无机氮、活性磷酸盐的时空分布特征,结果表明沙头角湾海水无机氮含量存在一定的季节差异性,活性磷酸盐指标变化范围较小,没有明显的季节性差异;采用富营养化指数评价方法对海水富营养化水平进行分析评价,结果表明沙头角湾海水富营养化指数在介于富营养和非富营养状态间波动;

Based on the data of field survey in November2016and the monitoring data from2007to2016,the temporal and spatial distribution characteristics of inorganic nitrogen and active phosphate in Shatou Bay were analyzed.The results showed that there was no significant difference The results showed that the eutrophication index of Shatoujiao Bay was analyzed by eutrophication index.The results showed that the seawater eutrophication index was significant and the seasonal variation was not significant.The results showed that the main source of inorganic nitrogen in Shatoujiao Bay was Yantian Wastewater Treatment Plant,which was the main source of inorganic nitrogen in Shatoujiao Bay.The results showed that the main source of inorganic nitrogen in Shatoujiao Bay was the same as that of Yantian Sewage Treatment Plant
