摘　　要：根据2006、2007、2008年5～10月份海洋环境监测航次调查的资料,分析了烟台四十里湾海域营养盐、COD、叶绿素a的分布特征、变化规律以及海湾的营养状况。结果表明,该海域营养盐随时间变化较为明显,磷酸盐秋季含量较高;叶绿素a最高值出现在9月份,COD整体变化不大;受人类活动和沿岸径流输入的影响,平面分布上营养盐、COD等的高值区出现在调查海域的东南部和西部。四十里湾海域无机氮浓度较高,N/P、Si/P值均大于Redfield比值,部分时节调查海域处于富营养化水平。The distribution features of water quality factors and nutrient status in Yantai Sishili Bay are discussed based on the monitoring results from May to October in 2006,2007,and 2008.The results indicate that the seasonal variation of nutrients is obvious;the concentrations of chlorophyll-a are the highest in September;the concentrations of COD show a little obvious change.There are abundant nutrients and COD in the area of the southeast and west of Sishili Bay because of human activity and riverine input.Based on the Redfield ratio（Si：N：P=16：16：1）,N：P and Si：P ratios are higher than Redfield,some months the nutrient status of Sishili Bay is eutrophied.
