黔西晚三叠世古植物生态学研究

A Study of the Paleophytoecology of Late Triassic Flora in Western Guizhou

本文通过对古植物生活环境的分析,定性地将黔西晚三叠世植物群分为湿生植物群落、低地植物群落和高地植物群落。利用叶相分析结合该植物群构成特征及当时的沉积特点,推断黔西晚三叠世为潮湿多雨、炎热的热带—亚热带雨林气候。

The paleophytoecology of the Late Triassic flora in Western Guizhou has been studied in this paper. This flora can be divided into three plant communities: (1) wetland plant, (2) upland plant and (3) lowland plant. By means of the research of the foliar physiognomy, characteristic of the flora and feature of the deposits, the flora may be a product under a damp and hot climatic condition in southern tropic of the north hemisphere.
