中国石炭纪古生物地理与古气候

本文从分析沉积及生物群出发,结合世界构造古地理和气候分带,将中国早石炭古生物地理分属三个生物区,即华夏生物区,中蒙海生物区和东冈瓦纳生物区。晚石炭世的生物分区与早石炭世大体相似。中国早石炭世的古气候分为华夏热带—亚热带区,准噶尔—兴安北温带区和西藏南部南温带区。其界线大致与古生物地理分区相合。晚石炭世中国气候分带与早石炭世相似。

CARBONIFEROUS PALAEOBIOGEOGRAPHY AND PALAEOCLI- MATE OF CHINA

In this paper we discuss the Carboniferous palaeobiogeography and palaeoclimate of china based on analysis of features of both sediments and organisms with background of structural palaeogeography and palaeoclimatic zones of the world. Three palaeobiogeographic realms in Early Carboniferous of China are recognized as follows: Tethysian, Boreal and Gondwanian realms. Late Carboniferous biogeography of China was similar to that of Early Carboniferous one with a few changes. Carboniferous palaeoclimate of China can be divided into three climatic zones in Early Carboniferous as follows: the Cathaysian tropical-subtropical zone, the Junggar-Xingan north temperate zone and the Gondwanian south temperate zone. Their boundaries approached to these of palaeobiogeography in the same time. The climatic zone of Late Carboniferous roughly corresponded with that of Early Carboniferous one.
