摘　　要： 2008年2月(冬季)、5月(春季)、8月(夏季)和11月(秋季)对深圳湾海水中石油烃进行4个航次的调查,研究深圳湾石油烃的分布特征,并对与其相关因素之间的关系进行了探讨。结果表明:整个深圳湾海域石油含量基本呈现出自湾内到湾外逐渐降低的平面分布特征;石油烃含量在季节上存在一定的差异:ρ冬季>ρ夏季>ρ春季>ρ秋季;石油烃与环境因子Chl-a、DIN存在极显著正相关(P<0.01),其相关系数分别为0.90,0.86,与DIP存在显著相关(P<0.05),相关系数为0.78。 Surveys on petroleum hydrocarbon in Shenzhen Bay were respectively carried out in February（Winter）,May（Spring）,August（Summer） and November（Autumn） 2008.The horizontal and seasonal distribution characteristics of petroleum hydrocarbon in Shenzhen Bay were acquired,combining the national standard methods.And the correlation was analyzed between PHC and DIN,DIP and chlorophyll-a.The results showed that PHC was decreased gradually from inside to outside of the Bay.The average content of PHC had a trend of winter〉 summer〉 spring〉autumn;The relationship between the petroleum hydrocarbon concentration and the environmental factors showed that there was obvious positive correlation between concentration of PHC and Chl-a、DIN（P〈0.01）,and there existed significant difference between PHC and DIP（P〈0.05）.At the same time the relative coefficient reached 0.90,0.86,0.78 respectively.
