模拟研究了停留在潮间带海域中低浓度0~#、20~#柴油对海洋浮游植物生长的影响,探讨了不同浓度和不同风化程度的低浓度油对藻类生长的影响;不同营养水平下,低浓度油对混合藻的生长影响。结果表明:通常存在在潮间带海水中的油(<1mg/L),对实验藻种虽具有某种程度刺激或抑制效应,但并不出现毒害死亡现象和不可逆转的生态效应;气相色谱分析表明浮游植物主要吸收C_(17)～C_(36)范围内的烃类,油的不同风化产物对藻类的生长影响显然不同;营养水平变化,改变了油对混合培养各藻种的生长速率的影响,从而引起了藻种间的增殖竞争效应。
The effects of low concentrations of 0 ~ # and 20 ~ # diesel oil staying in the intertidal zone on the growth of marine phytoplankton were studied. The effects of different concentrations and different degrees of weathering on the algae growth were discussed. Under different nutrient levels , Low concentrations of oil on the growth of mixed algae. The results showed that oil (<1 mg / L) usually existed in intertidal seawater and had some stimulation or inhibition effect on experimental algae species, but did not cause toxic death and irreversible ecological effects. Gas chromatography The results showed that the phytoplankton mainly absorbed hydrocarbons in the range of C_ (17) ~ C_ (36), and the different weathering products of oil obviously had different effects on the growth of algae. The change of nutrient level changed the growth rate of oil to mixed algae Which caused the proliferation competition effect between algae species.
