摘　　要：根据2015-05和2015-08莱州湾及黄河口邻近海域2个航次的现场调查资料,研究了莱州湾营养盐分布特征及影响因素。结果表明,莱州湾表层营养盐浓度分布总体上呈现由西南部湾顶向东、北方向递减的趋势。浮游植物生长繁殖对海湾中央海域营养盐分布有一定影响。春季营养盐分布一定程度上受海湾内环流的影响,但在夏季环流作用不明显。黄河入海口改道变为东北方向入海后,其对莱州湾营养盐输入的影响已很小,陆源营养盐主要来源转变为以小清河为主的西南部入湾河流,据此建议将莱州湾西南部入海河流作为营养盐类污染物重点控制对象。Based on in-situ data obtained in May and August,2015,the characteristic of nutrients distribution and influencing factors in the Laizhou Bay and Yellow River Estuary were investigated.The results indicate that the distributions of nutrients in surface water have demonstrated a decreasing trend from the southwest to the northeast of the Laizhou Bay.Phytoplankton growth and reproduction have a certain influence on the distribution of nutrients in the center of the bay.In spring,the clockwise circulation has a certain impact on the features of nutrients distribution in the bay;however,this role weakens in summer.The Yellow River has little effect on the source of nutrients in the Laizhou Bay after diversion of its channel into the northeast,and especially the Xiaoqinghe River become the main source of terrigenous nutrients from the southwest into the bay.Accordingly,it should pay more attention to the southwestern rivers of the bay for the nutrients pollution control.
