中文摘要：

海底冷泉区是海洋能源和生物资源同时富集的一类特殊区域。底栖有孔虫群落及其地球化学组成是海底冷泉区发育的重要指示标志之一。海底冷泉区的底栖有孔虫及其碳同位素研究,对于探讨冷泉演化、评估古冷泉甲烷排放对全球气候变化的影响有重要的研究意义。综述了全球一些主要冷泉区的底栖有孔虫研究方法及其进展,对比了各冷泉区底栖有孔虫群落结构的主要特征及地域差异,评述了冷泉区底栖有孔虫的碳同位素记录特征、影响因素及其对冷泉活动的潜在指示意义,最后提出了南海北部冷泉活动区底栖有孔虫方面的研究展望。

英文摘要：

Cold seeps are typical areas abundant both in marine energy resources and biological resources.Benthic foraminiferal assemblages and the geochemical composition of their carbonate shells,such as δ13C,are important indicators of cold seep.These proxies have important significances in the study of the paleo-cold seeps evolution,and also in the evaluation study of methane released from cold seeps and their effects on global climate changes.This paper reviews the methods and recent progress in cold seep benthic foraminiferal studies in some modern active cold seeps.Through comparison the main characteristics of modern cold seep benthic foraminiferal faunal and the discrepancy between different seepages are presented.It also reviews the carbon isotope response of benthic foraminifera in different cold seep areas and its possibly influential factors.Finally we give a general outlook for the study of cold seep benthic foraminifera in the northern South China Sea.
