摘要
于2016年7月19—24日,在长江口邻近海域5个连续站获取了温度、盐度、营养盐浓度、化学需氧量、叶绿素a浓度和总悬浮颗粒物浓度等18个海洋参数数据,通过综合运用K值聚类、斯皮尔曼相关性分析及主成分分析法等,划分了夏季在122.7°E附近的水团分布情况,并进一步探究了各海洋参数间的相关性及其驱动力.结果表明:夏季长江口调查海域可划分为3个水团,初步判断为长江冲淡水、陆架混合水以及两者相互混合而成的水团;海洋参数主要受物质垂向输送、浮游植物生产和悬浮颗粒物3个因素控制.
From July 19 to July 24 in 2016,five time-series stations in the Yangtze River Estuary adjacent sea area were sampled and 18 marine variates such as salinity,temperature,nutrient concentrations,chemical oxygen demand,chlorophyll a concentration,total suspended particles concentration,etc,were obtained.Water masses and correlations between these marine variates and their driving forces around 122.7°E during summer were explored using approaches including K means clustering,Spearman correlation analysis and principle component analysis.Results show that the investigated sea area could be divided to three water masses,the Yangtze River diluted water,the shelf mixed water and the water mixed by them.The environmental marine variables were influenced mainly by vertical transport,primary production and suspended particulate matter.
