滩涂生态系统模拟器用于阐明滞留燃油对滩涂生态系统的影响。结果表明，石油泄漏通过减少沉积物捕食者造成的捕食压力来增加沉积物上的附生生物。漏油事件发生后大约一个月，大型底栖动物的总种群密度恢复了。漏油事件后，表面沉积物的氧化还原电位降至负值，整个沉积物的厌氧条件似乎是大型底栖动物种群密度下降的原因。海水渗入石油搁浅沉积物的渗透量减少到没有溢油情况下的三分之一。大约一个月后入渗量的恢复与大型底栖动物种群密度的恢复相一致。这一结果表明大型底栖动物种群高度依赖于海水的渗透。 (C) 2004 Elsevier Ltd. 保留所有权利。
Tidal flat ecosystem simulators are used to clarify the effects of stranded fuel oil on tidal flat ecosystems. Results show that oil spills increase the periphyton on sediment by decreasing the predation stress caused by deposit feeders. About a month after an oil spill, the total population density of the macrobenthos recovered. The oxidation-reduction potential in the surface sediment drops to a negative value after the oil spill, and the anaerobic condition throughout the sediment seems to be responsible for the decrease in the population density of the macrobenthos. The infiltration volume of seawater into the oil-stranded sediment decreases to a third of that without the oil spill. The recovery of infiltration volume after about a month coincides with the recovery of the population density of the macrobenthos. This result suggests that the macrobenthic population is highly dependent on the infiltration of seawater. (C) 2004 Elsevier Ltd. All rights reserved.
