摘要
研究1997～2004年胶州湾海域石油烃的含量，分析了其时空变化规律。结果表明。近几年胶州湾的石油烃浓度变化范围为0．03～430．00μg／L，平均值为44．56μg／L，其中82％属于二类以上海水。湾东部和东北部污染较重的区域石油烃的浓度较高。总体来看，1997～2004年之间，石油烃的年平均浓度变化不大，变化范围为28．52～50．94μg/L，只有2003年石油烃的年平均浓度超过了50μg／L。胶州湾石油烃含量的季节变化规律大致为8月份最高，其次是春季，最小的是秋季。石油烃与其它环境因子的回归分析表明。石油烃与DIN和DIP有着较好的正相关性，说明两者可能有相似的来源。
The petroleum hydrocarbon concentrations and distribution features in Jiaozhou Bay from 1997 to 2004 are analyzed and discussed. The results show that the mean concentration of petroleum hydrocarbon is 44.56μg/L, varying from 0.03 to 430.00μg/L in Jiaozhou Bay and at most of the survey sataions, the water quality reached Grade Ⅱ according to the National Seawater Standard. The petroleum hydrocarbon concentrations are higher in the east and northeast of the Bay. In adition, the variation of annual average petroleum hydrocarbon concentration, which was in the range of 28.52—50.94μg/L, was not significant during the survey period and only in 2003, the petroleum hydrocarbon concentration was higher than 50μg/L. The seasonal variations in petroleum hydrocarbon in Jiaozhou Bay indicate that among the three seasons, the average concentration of petroleum hydrocarbon was highest in August, lower in May, and lowest in October. The relationship between the petroleum hydrocarbon concentration and the environmental factors shows that there exists a certain positive correlation between the petroleum hydrocarbon concentration and the dissolved inorganic nitrogen as well as phosphate, suggesting that they might come from a similar source.
