秦山核电站邻近水域大肠菌群和粪大肠菌群的分布

Distributions of coliform bacteria and feal coliform bacteria in the waters near Qinshan Nuclear Power Station

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。

The distributions of conform bacteria and feal coliform bacteria in the surface water neary Qinshan Nuclear Power Station were tentatively investigated and analysed in the four seasons from April1989 to January1990. The results show that the bacterial density ranges from 0 to 3500 cell / dm3, and can be found out throughout the year. The distribution in the coastal water is higher than in the outside, the falling tide is larger than rising tide, the south of Qinshan is more than the nouth. The bacterial number changed with the environmental factors such as water temperature, salinity, tide and so on.
