连云港近岸海域富营养化水平的季节性变化及其影响因素
Seasonal Variations of Eutrophication and the Influential Factors in the Adjacent Water of Lianyungang
摘要
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 e-valuated. 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.关键词
