• 摘要：分散剂对某些海洋生物的抑制以及促进初级生产力的现象已为一些研究所证实,而分散剂与原油的混合对生物的影响,由于其污染的增效作用更引起了人们的注意,但上述的研究多见于温带和寒带海域,对于热带、亚热带海域研究尚少。因而,了解污染物对亚热带海域生物区系的影响及地理位置的不同所引起的污染物效应的差别是本研究的中心问题。

• Abstract：Effects of dispersant Corexit 9527 and its mixture with crude oil on the organism in an enclose ecosystem were investigated in Xiamen harbour during May 23 to June 6,1986. During the first 11 days of the experiment, the abundances of phytoplankton and zooplankton were significantly inhibited by the mixture, while Corexit 9527 alone had no influence on the organism except inhibited the development of herbivorous copepodas to some extent. After the eleventh day of the experiment, a bloom dominated by Nitzschia closterium occurred, corresponding to a decrease of salinity and an increase of temperature.Changes in the abundances of bacteria and flagellates during the experiment are discussed.
