| 摘 要： | 通过分析位于钦州湾的2个海水水质自动监测站2009-2010年的自动监测数据，发现钦州湾水温、盐度、溶解氧季节变化明显，海水表层水温变化是引起钦州湾溶解氧含量变动的主要原因；钦州湾海水表层盐度及pH值主要受钦江、茅岭江径流及潮汐涨落的影响；处于河口区域，受大陆径流影响显著的海域使用海水水质标准来评价有欠妥当。

| Abstract: | Based on the data feedback by two auto-monitoring stations in Qinzhou Gulf during 2009-2010, we analyze the temporal and spatial variation of temperature, salinity, DO and pH. The results showed that the three indexes had significantly seasonal variation. DO change was primary caused by the variation of surface tem- perature,Salinity and pH in the gulf was influenced mostly by the surface runoff of Qin river and Maoling river and the tide. It is irrelevancy to use marine water quality standard to evaluate water quality in estuary that were significantly influenced by overland runoff. |
