象山港中西部水文特征与赤潮形成的关系

Relationship between the Hydrologic Characteristics in the Western Central Part of Xiangshan Harbour and the Formation of Red Tide

一、前言象山港位于浙江省中部,介于东经121°25′～122°03′、北纬29°24′～29°48′之间。象山港从下游的莲花附近朝西南纵深内陆,形成峡道形海湾。由主港和三个支港(西沪港、黄墩港和铁港)组成。海域面积约为392平方公里,其中10米等深线以内的海域约占60%,主湾中心线全长约60公里,港内水深由上游向下逐渐增深。

On the basis of the temperature-salinity data monitored monthlyin the western central part of Xiangshan Harbour from January,1988through March,1989 and the tidal current data recorded at the threeobservation stations,the reasons for the formation of red tidein Xiangshan Harhour were analysed from the viewpoints ofoceanography.
