放射虫现代生态学的研究进展及其应用前景——利用放射虫化石揭示古海洋、古环境的基础研究

放射虫以其不易溶解的硅质壳体在古海洋、古环境研究中起着不可替代的作用，其种类组合与海洋物理、水文环境有着很好的对应关系。随着放射虫在古海洋环境研究中的广泛应用以及研究手段的改进，放射虫现代生态学研究在世界各大洋得到了广泛开展。中国加入综合大洋钻探计划，势必会加快JP2]我国古海洋学的研究步伐，放射虫作为海洋微体古生物中的一个重要类群，其生态学知识是重建古海洋、古环境的基础。因此，有必要向我国学术界提供放射虫现代生态学的研究成果及最新发展趋势，促使我国放射虫的研究与国际接轨，以提供更多的古海洋、古环境替代性指标。

Progress and Prospect in Research on Living Radiolaria Ecoloy: A Basic Study of Paleoenvironmental and Paleoeanographic Reconstructions

Polycystine radiolarians play an important role in the research of paleoceanography and paleoenvironment because of their indiscerptible siliceous skeletons and the good corresponding relation between radiolarian assemblage and physical oceanography, hydrographical conditions. With widespread radiolarian application in paleoceanography reconstruction and the improvement of research measures, living radiolarians have been widely studied in the world. China has participated in such deep-sea research programs as IODP, which should accelerate the step of the study of paleoceanography. Radiolaria is an important fauna among the marine micropaleontology, whose ecology knowledge is the base of paleoceanographical and paleoenvironmental reconstruction. Therefore, it is very necessary to offer the latest achievement and progress trends in ecological studies on living radiolarians to research communities, with a view to making our research on radiolarian keep pace with the world and offering more proxies of paleoenvironment and paleoceanography.
