本文对秦山核电站邻近水域表层海水中大肠菌群和粪大肠菌群的分布作了春、夏、秋、冬四季的初步调查分析。结果表明,大肠菌群和粪大肠菌群的分布范围为0～3500个/dm~3,并在一年四季中都能检出大肠菌群和粪大肠菌群。其分布趋势为沿岸高于外侧,退潮大于涨潮,南部多于北部。细菌的数量随水温、盐度、潮汐等环境因子的变化而变化。
In this paper, the distribution of coliform bacteria and fecal coliform in surface seawater of Qinshan Nuclear Power Station was investigated in spring, summer, autumn and winter. The results showed that coliform and fecal coliforms distributed in the range of 0 ~ 3500 / dm ~ 3, and coliform bacteria and fecal coliform bacteria could be detected in all seasons. Its distribution trend is higher than the outer coast, ebb tide than tide, south more than the north. The amount of bacteria varies with the environmental factors such as water temperature, salinity and tide.
