为了评估羊窝头防波堤、旗台作业区等相关工程建设后连云港港内的水质现状，在2013年7月及12月开展了两次水质大面调查，分析了港口区域的表层海水溶解氧、无机氮、无机磷、化学需氧量以及石油类的浓度分布特征，浓度分布分析结果表明港池内水质略差于港外水质，港池末端水质相对较差。采用单项指数法对测量期间的水质进行评价，分析表明两次测量期间港池内了水质单项指标满足港内第四类海水标准，此外还采用富营养化指数方法，对港区内的富营养化程度进行了分析，研究发现港区内富营养化指标略有超出，无机氮为潜在性富营养化的限制环境因子，需要加强港口内部及周围区域无机氮排放的控制。

In order to evaluate the water quality status after the construction of Yangwotou breakwater and Qi?tai operational zone inside the Lianyungang Port, two surveys of water quality were taken in July and December of the year 2013. The distribution of inorganic nitrogen, inorganic phosphate and chemical oxygen demand as well as the petroleum in the surface waters of harbor area were analyzed. The results show that the water quality in the ba?sin is slightly worse than the outer harbor water quality with the relatively poor water quality in the basin end. The index method was adopted to analyze the water quality during the observation period. During the two surveys, the water quality in the harbor meets the national grade four water standards. Moreover, the eutrophication index meth?od was used to analyze the eutrophication state in the harbor. Within the port the water is slightly eutrophication, and the inorganic nitrogen is the limiting eutrophication factors. Control on the pollution discharge will be tightened with special focus on the inorganic nitrogen discharge.
