我国南方二叠纪生物礁与造礁生物古生态的研究

STUDY ON PERMIAN REEFS AND PALEOECOLOGY OF REEF-BUILDING ORGANISMS.

二叠纪生物礁在我国南方分布广泛。研究证明,礁与油气关系密切,具有广阔的开发前景。二叠纪造礁生物主要为海绵及钙藻类,海绵的个体古生态及群落古生态学研究揭示了礁的形成和发展过程,从而为成礁模式的提出及开展中国南方二叠纪礁、丘、滩对比研究提供了重要依据,并使生物礁研究提高到一个新的层次。

Middle and Upper Permian reefs are widely distributed and well developed in south China. Sponges (sphinctozoans,inozoans and sclerosponges)are one of the most important frame-building organisms. Algae have played an exceedingly important role in the development of the reefs. Abundant records of Permian reef communities exist in South China. Most reefs clearly exhibit distinct cycles, which are consistent with the reef community flourishing. Results of the author research in individual paleoecology and community paleoecology furnished fresh evidences for further study on the development of Permian reefs of south China.
