| 摘要：泰国东北部柯叻府及邻区中一新生代木化石非常丰富并保存有完好的解剖构造，泰语论文范文，是探索热带植被历史、古气候演化以及古环境变迁等问题的重要实证材料。最近的野外调查和专题探讨确认该地区中一新生代木化石11科19属约50个种或种级分类单元，分别隶属于裸子植物和被子植物两大分类群，其中有5科7属20种(包括未定种)为前人在泰国未曾报道的类型。当前木材化石群揭示出在中生代后期，泰语论文，泰国东北部热带针叶树植被以南洋杉科为主；在中新世一更新世时期，该地区主要发育落叶和常绿阔叶树植被，代表热带气候环境。 Abstract：Korat and adjacent areas in Northeast Thailand Cenozoic fossil wood is very rich and preserved intact anatomical structure, explore the tropical vegetation history, evolution of paleoclimate and paleoenvironment changes of important empirical materials. Recognition of recent field investigation and study of the topic in the region in the Cenozoic fossil wood 11 families 19 genera about 50 species or species level taxa, belonging to gymnosperms and angiosperms two classified groups, including 5 families, 7 genera 20 species (including undetermined species) for the type of Thailand has never been reported in the past. Current wood fossil group revealed that in the late Mesozoic, northeast Thailand tropical conifer vegetation to Araucariaceae; in Shiyi Pleistocene period, the region mainly developed deciduous and evergreen broadleaf tree vegetation, on behalf of the tropical climate. 引言：泰国地处东南亚中南半岛,不仅现代热带植被 及生物群发育,而且以其地质历史时期独特的地理 位置和特有的中一新生代化石记录备受地质古生物学 界的广泛关注口3口.尤其是泰国东北部柯叻高原及 邻区中一新生代木化石非常丰富,解剖构造保存完 好,成为了解泰国以及东南亚地区热带 |
