摘要:
运用营养状态指数法,并结合CN/CP的潜在性富营养化划分方法,以2012年5月～2013年2月连云港近岸海域4个季节的水质调查资料为基础,分析了该海域4个季节的富营养化水平及CN/CP的关系,同时对其影响因素进行探讨.结果表明:(1)连云港近岸海域水体基本呈富营养状态,4个季节的富营养化指数的平面分布特征基本相同,主要表现为近岸高、离岸低,由沿岸向离岸方向逐渐降低的趋势; 4个季节的富营养化指数均值秋季EI(2.06)>春季EI(1.58)>冬季EI(1.53)>夏季EI(1.42),富营养海域的面积由大到小依次为秋季、春季、夏季、冬季,富营养程度较严重的区域主要位于排淡河口和灌河口附近海域.(2)连云港近岸海域4个季节均处于磷中等限制潜在性富营养水平,不同季节CN/CP比值由大到小的顺序依次是夏季(138.1)、春季(110.7)、秋季(86.3)、冬季(65.1).(3)连云港近岸海域富营养水平与盐度、pH和溶解氧有显著的负相关关系,表明陆源径流对该海域海水的富营养化水平起着重要的调控作用.
Abstract:
Based on the monitoring data of oceanographic survey from four seasons including 39 stations carried out in the adjacent water of Lianyungang from May 2012 to February 2013,the seasonal variations character of eutrophication was evaluated.A method of nutrient status index and CN/CP value were used in analysis,and the influential factors was discussed.Some conclusions were as follows:(1)The results showed that horizontal distributions of EI were similar in the four months,indicating that the EI value was high in the coastal waters,and decreased gradually away from the shore,and showed a sequence of autumn(2.06)greater than spring(1.58)greater than winter(1.53)greater than summer(1.42)in the seasonal variation.The major polluted areas lay at the mouth of Paidan and Guanhe.The area of the eutrophic waters of autumn was highest,followed by spring,summer,winter.(2)The adjacent water of Lianyungang could be classified as a phosphorus-medium limited potential eutrophication area,the value of CN/CP of summer(138.1)was highest,followed by spring(110.7),autumn(86.3),winter(65.1).(3)The eutrophication index(EI)showed significant negative relationship with salinity,pH and DO,which showed that the temporal and spatial distribution of eutrophication index were mostly regulated by runoff.
