笔者在研究了新疆地区的二迭纪地层及其所含的植物化石后,发现对新疆二迭纪的古植物地理分区,以及安加拉和华夏两大植物区系的关系问题的研究,是有意义的。新疆北部地区(即北疆的准格尔、吐鲁番二个盆地)二迭纪的植物基本上属“安加拉”型,即与苏联库兹涅茨盆地的库兹涅茨植物群(也称“安加拉”植物群)相类似,但其中也有不少与华夏植物混生的情况出现。新疆南部的塔里木盆地则是以华夏植物为主,在北缘亦有典型的安加拉型分子。总之,新疆地区在研究安加拉植物区系与华夏区系的关系上有重要意义及独特的地理上的价值。笔者于1977年3月参加在新疆召开的北方地槽地质会议期间,在会上粗略介绍了有关新疆二迭纪植物的区系问题,现整理成文,错误和不成熟之处难免,望批评指正。对提供资料和化石的新疆石油局、地质局、156煤田地质勘探队等单位和有关人士,笔者深表谢意。
After studying the Permian strata in Xinjiang and the plant fossils it contains, I found that the study on the relationship between the Permian ancient plant geographical division in Xinjiang and the relationship between Angara and Huaxia flora was meaningful. The northern part of Xinjiang (that is, the Junggar and Turpan two basins in North Xinjiang) basically belong to the “Angara” type, which is similar to the Kuznets flora of the Soviet Kuznets Basin “Angara” flora) are similar, but there are also many mixed with the emergence of Chinese plants appear. The Tarim Basin in southern Xinjiang is dominated by Cathaysia plants and also typical Angara type molecules in the northern margin. In conclusion, Xinjiang is of great importance in studying the relationship between the Angara flora and the Huaxia fauna and its unique geographical value. During the Northern Geosyncline Conference held in Xinjiang in March 1977, the author gave a rough introduction to the flora of the Ordovician in Xinjiang in March 1977. It is unavoidable that the writings, mistakes and immatures are inevitable. . I am very grateful to the units and people involved in providing information and fossils such as the Xinjiang Bureau of Petroleum, the Bureau of Geology, and the Coal Geological Exploration Brigade 156.
