摘要：为探明不同潮水环境条件下长江口南支宝山近岸水域水环境的变化及其主要影响因素，于2015年5一6 月期间在大、小潮及涨、落潮不同潮期条件下进行水环境监测。监测结果表明，调查水域水质除总磷、总氮部分站位劣于二类水质标准，氨氮符合二类水质标准外，其他参数均符合一类水质标准。Cu，Zn，Pb,Cr和悬浮物明显表现出大溯期含量高于小溯期的特征，其他参数在不同溯期含量差别不大。相关性和主成分分析结果表明，物源输
人是影响该水域水环境的主要因素，其次是生态环境的影响，人为污染也不可忽视。关键词：长江口南支；近岸水域；水环境；影响因素

Abstract: Inshore waters environment was monitored from May to June in 2015 under different levels of tide, in order to find the influencing factors in the area adjacent to Beoshan in the southern branch of the Yangtze estuary. Results suggested that water quality of ammonia nitrogen was Grate 2, total phosphorus and total nitrogen were inferior to Grade 2, while other envi-ronment parameters were Grate 1. It appeared that the concentrations of Cu, Zn, Pb, Cr and suspended solids during spring tide were obviously higher than those during neap tides, while there were little differences among other environment parame-ters. By correlation analysis and principal component analysis, it showed that the principal factor influencing water environment was source input or eco-environment, while man-made pollution affected environment least, not to be neglected though.
