| 摘 要： | 海洋浮游植物生产力和群落结构在地质年代中的变化对深入理解碳循环的演变规律和机理有着重要的意义.生物标志物方法作为一种较新的研究手段,其含量与比值的变化被广泛用于浮游植物生产力与群落结构变化的重建.讨论了生物标志物方法在各大洋及我国边缘海的应用现状,提出了生物标志物的细胞产生量及其在环境中的保存效率的2种主要不确定因素,使目前多参数生物标志物方法只能够半定量地重建古生产力与群落结构的变化.针对我国边缘海,提出有必要通过现场调查和实验室培养建立生物标志物含量(比值)与浮游植物生产力(群落结构)的定量关系式,以达到能够定量重建生产力和群落结构变化的目的.

| Abstract: | Revealing variations for phytoplankton productivity and community structure is important for understanding ocean carbon change mechanisms. Variations of biomarker contents and ratios have been successfully used in reconstructing phytoplankton productivity and community structure changes. Reviews of applications of muti-biomarker approach in the open ocean and China′s marginal seas suggest that the two major uncertainties associated with cellular contents of biomarkers and preservation efficiency of different biomarkers in the environments have limited the application of biomarkers to the semiquantitative reconstruction of paleoproductivity and community structure changes. It is suggested that, in order to more accurately estimate paleoecosystem changes, future research needs establishing the quantitative formula between biomarker content and productivity, and between biomarker ratios and community structure, by use of in-situ data and algal culture experiments. |
