有关中国奥陶纪古生物地理问题,无论过去还是近年来,都曾有过一些论述(卢衍豪等,1976;陈均远,1980;穆恩之,1980,1983;王鸿祯,1985;戎嘉余、陈旭,1987;李志明,1988;B.Y.Lin & B.D.Webby,1989;汪啸风,1989;S.C.Finney & X.Chen, 1990)。但关于古气候的研究至今还涉及的不多。随着古生物学、生物地层学和生态地层学研究的日趋深入,尤其是近年来在全球奥陶纪古地理重建和古生物地理研究方面又获得新的进展(C.R.Scotese & W.S.McKerrow,1990,1991),这就为重新认识和研究中国
There have been some expositions on Ordovician palaeontological issues in China both in the past and in recent years (Lu et al., 1976; Chen Junyuan, 1980; Mu’enzhi, 1980,1983; Wang Hongzhen, 1985; Rong Jiayu, Chen Xu, 1987; Li Zhiming, 1988; BY Lin & BD Webby, 1989; Wang Xiaofeng, 1989; SC Finney & X. Chen, 1990). However, the research on paleoclimate is still not involved so far. With the development of palaeontology, bio-stratigraphy and ecological stratigraphy, especially in recent years, new progress has been made in the research of Ordovician paleogeography and paleobiology in the world (CR Scotese & WS McKerrow, 1990, 1991) This is to re-understand and study China
