本文研究了深圳湾牡蛎体石油烃含量的季节变化特点。结果表明,牡蛎体的石油烃含量从春季到初秋前呈上升趋势,夏末达到最高值,其后趋于下降,到冬季有所回升,达次高值后翌年春季下降到原来的含量水平。冬季节平均含量的大小顺序为:夏季>冬季>秋季>春季。深圳湾牡蛎体石油烃含量的季节变化主要与水体石油烃浓度和牡蛎本身生殖循环引起的总脂类量及体重的变化有关。此外,水温、盐度的变化亦有某些间接的影响。文章对上述影响因子进行了讨论。
In this paper, the seasonal variation of petroleum hydrocarbon content in the oyster of Shenzhen Bay was studied. The results showed that the petroleum hydrocarbon content of the oyster body increased from spring to early autumn, reached the highest value in late summer, then decreased and then returned to the winter, reaching the original level in the following spring after reaching the next highest value. The order of the average content of winter season is: summer> winter> autumn> spring. The seasonal variation of petroleum hydrocarbon content in the oyster of Shenzhen Bay is mainly related to the change of the concentration of petroleum hydrocarbons in the water column and the total lipid content and body weight caused by the oyster itself. In addition, changes in water temperature and salinity also have some indirect effects. The article discussed the above factors.
