【摘要】 本文根据1989年4、7、10月和1990年1月(春、夏、秋、冬)秦山核电站邻近水域零点生态调查和水质监测结果的资料整理而成。经研究证明,该海域是河-海混合水域,盐度从小于3至12之间变化,受杭州湾的涌潮、风浪的影响,水体混合比较强烈,悬浮颗粒物质的含量比长江口高。由于该测区所处的海岸、海底地形,生态系统、径流输入以及水体交换状况不同,故其海洋学特征也不相同。更多还原

【Abstract】 In this paper, the results of investigation were reported in the sea area near the Qinshan Nuclear Power Station from April 1989 to January 1 990.lt shows that the survey area is a mixing zone.There are high concentration nutrient (N, P, Si), dissolved oxygen, and suspended particulate materials in the water body.The dissolved material is mainly controlled by open sea water.In the case of higher suspenaed particulate materials, the concentration of dissolved trace metals is lower, so there is not contamination in surveying area. But from the point of riew of pollution, the concentration of COD is higher than quality criteria for water.All environmental chemical factors are little change.lt shows clearly that the exchange of water of surveying area with open sea isn’t strong.The high concentration of nutrient isn ’t influenced by biology, and will further provide open sea with rich-in-nutrient water.The bottom soil in the area is mainly sand on which is poor in organtc matter.N3/4Pvalue being high shows that the concentration of N is so high that it influenced seriously the water quality of the sea.更多还原
