| 摘 要： | 本文于2003年1月到2005年12月对罗源湾海区表层海水中的粪大肠菌群数量和分布进行了调查监测。监测结果表明：罗源湾表层海水中粪大肠菌群的数量在〈2～540个／100mL之间，3年中月平均高值出现在8到10月份，低值出现在1到4月份，且年平均值呈逐年递增。原因分析发现，影响湾内海水中FCB的月平均值数量变化的最主要因素是降水量。另外通过多点采样结果比较，发现罗源湾表层海水中FCB的空间分布呈现为：湾内腹海区〉湾中间海区〉湾口海区。通过国家海水水质标准（GB3097-1997）对本次的调查监测结果进行评价，从2003年到2005年罗源湾海区海水中粪大肠菌群的达标率分别为100％，98．0％和97．9％，表明罗源湾海区表层海水的FCB污染相对较轻。

| Abstract: | Fecal Coliform Bacteria (FCB) of marine waters was monitored in Luoyuan Bay from January, 2003 to December, 2005. The results showed that number of FCB in marine water samples ranged from no detection(＜2 cfu/100mL)to 540 cfu/100mL in Luoyuan Bay. Values of FCB during August to October were significantly higher than those during January to April during three year period. Monthly changes of FCB values at each year period were mainly due to monthly precipitation. In addition, compared with FCB values in difference sample sites, values of FCB in Bay-head were significantly higher than those in middle of bay and Bay-mouth, Luoyuan Bay. However, values of FCB in Bay-mouth were significantly less than those in middle of bay. The ratios to the par of FCB in 2003, 2004, and 2005 years were 100%, 98.0%, and 97.9%, respectively. Therefore, we considered that the pollution of FCB of surface marine water in Luoyuan Bay was not serious. |
