摘　　要：2016年9月和2017年6月对射阳河近海段的温度、浊度、盐度、叶绿素a、酸碱度、溶解氧(DO)、氨氮(NH3-N)、总磷(TP)和高锰酸盐指数(CODMn)进行监测分析。结果显示:不同时期温度相差不大,入海口浊度、盐度和TP浓度远高于上游,下游pH值和DO浓度高于上游,2016年9月NH3-N和CODMn浓度大于2017年6月。上游入境客水带来的有机污染影响较大,同时入海口在2016年9月有机污染较重,入海口富营养化水平也比上游高。2016年9月综合水质达到Ⅳ类标准,2017年6月达到Ⅲ类标准,盐淮高速断面和建新村断面综合水质较差,CODMn、DO和TP是主要污染物。相关性分析显示叶绿素a、DO和pH值三者正相关,TP、浊度和盐度均由人为活动导致,农业生产是NH3-N和CODMn的主要来源。Temperature,Turbidity,Salinity,Chlorophyll a,pH,DO,NH 3-N,TP,and COD Mn of the Sheyang River in coastal section were measured at September,2016 and June,2017. The temperature of the Sheyang Riverin coastal section was similar at the two different times. The turbidity,salinity,and TP in estuary section were significantly higher than those in other upstream sections. The pH and DO in downstream sections were higher than those in the upstream sections. The NH 3-N and COD Mn at September,2016 were higher than those at June,2017. Organic pollution brought by foreign water entering from upstream had a great impact,and the estuary experienced serious organic pollution in September of 2016,with the eutrophication level at the estuary also higher than upstream. The integrated water quality in September of 2016 reached Category IV standards,and Category Ⅲ in June,2017. The integrated water qualities of the Yancheng-Huai’an Expressway cross section and the Jianxin Village cross section were rather poor,with CODMn,DO and TP as the main pollutants. There were positive correlations between Chlorophyll a,DO,and pH. The TP,turbidity,and salinity were primarily caused by human activities,and agricultural production was the main source of NH 3-N and COD Mn .
