【摘要】 本文从植物形态学、解剖学等方面入手,结合沉积学研究,详细讨论了贵州西部晚二叠世煤系植物古生态,划分出四种基本群落类型,即以石松类为优势植物的沼泽群落;以芦木类为优势植物的岸边群落;以大羽羊齿、辉木等为优势植物的中生群落和以裸子植物为优势植物的高地群落。给出了各种群落的种类组成和结构特征,初步恢复了本区晚二叠世的植被面貌。文章最后简要讨论了火山喷发与森林火灾之间,动物与植物之间的相互关系,认为森林火灾可能是本区晚二叠世常见的自然现象。更多还原

【Abstract】 The paper discusses in detail Palaeoecology of flora from coal measures of the Upper Permian in Western Guizhou based on investigation of morphology,anatomy of paleobotany,palynology and sedimentology. Four main floras are as the following, the swamp floras dominated by Lycopodiales,the water front floras dominated by Calamites; the floodplain floras dominated by Gigantopterides,Psaronius and the upland floras dominated by conifers,Ginkgos and Pteridosperms. The paper describes the composition and structural features of different types of floras and it restores gradually the vegetation of the Late Pemian in this area.Finally,the paper discusses the relation between volcanic eruption and forest fire,and the relation between animals and vegetables. It considers that the forest fires may be a natural phenomenon commonly found in the Late Permian in this area.更多还原
