【摘要】 应用因子分析法对2006年5月长江口及邻近渔业水域14个水质指标的监测数据进行了分析研究。结果表明:无机氮和硅酸盐与水体中的温度、盐度和pH水平均呈现较强的相关性,其水平和分布状况主要受海流状况的影响。因子分析中第一个因子的贡献率为37.54%,主要反映了陆源污染对水体的影响。综合因子得分排序表明位于长江口的1、2号站位污染最为严重。更多还原

【Abstract】 The quality of Yangtze River Estuary and Adjacent East China Sea in May 2005 was analysed by using factors analysis.The results showed coefficients among DIN and salinity and water temperature,salinity and pH had a higher positive correlation.Whose level and distributing were mostly effected by the ocean current.The first factors contributed 37.541%, which represented the external sources of pollution.And the components score showed the stations(1,2) on Yangtze River Estuary had the most serious pollution problem.更多还原
