摘　　要：本文将以“震旦生物群”来总括中国境内所发现的震旦纪范围内的后生生物化石类群,避免更多具有同时代意义的地方特色的名词术语。本文归纳了“震旦生物群”各类群的主要组合面貌,强调其演化特征和地层对比意义,并总结了迄今为止中国“震旦生物群”的地理分布和地层分布。Since the 1970s, Precambrian metazoans and metaphytes, such as megalgae, soft-body fossils, sponge spines, skeletal fossils and trace fossils in the whole Sinian biota have been studied in China, except stromatolites and microplants. A series of biotas or floras have been set up in different localities, including the Huainan biota, Liaonan biota, Lantian flora, Miaohe biota, Gaoji-ashan biota and Xilingxia biota. In order to carry out a more intensive study of Precambrian palaeontology and grenetic stratigraphy, facilitate an intercontinental correlation of those biotas and explore the origins and histories of various phyta in the Phanerozoic, it is advisable to adopt the concept of the 'Sinian biota', which includes various types of metazoans found in China. In order to avoid using many other local terms to designate typical biotas of the same ages, the authors summarize and describe the features of the main assemblages of the Sinian biota and their evolutionary characteristics and stratigraphic correlation, and sum up their geographic and strati-graphic distributions.
