基于华南古生代(主要从志留纪到二叠纪,涉及少许早三叠世)植物资料,通过数据综合分析,揭示华南古生代陆生维管植物多样性演变特征:华南古生代(志留纪到二叠纪)陆生维管植物多样性总体呈现上升趋势;在志留纪,陆生维管植物处于最早期演化阶段,其多样性处于建立阶段;从早泥盆世到早石炭世,陆生维管植物处于分化和分异阶段,其多样性起伏较大,植物类型的更替快,是陆生维管植物物种类型发展最快的时期,植物从开始到完全占据不同陆地生态系统;从二叠纪早期开始,植物的多样性迅速发展,并在中晚二叠世达到了整个古生代植物多样性的最高峰.华南晚古生代海、陆生物多样性对比显示:在共同的地球生态系统中,华南晚古生代动、植物多样性协同发展,体现了海、陆地生态系统中多样性演变的各自特征.F/F和二叠纪末生物大灭绝事件造成了陆生维管植物多样性变化,前者主要表现为多样性在Frasnian期大幅下降,后者除了多样性极度下降外,植物类群发生了根本的更替.
Based on the data from the Paleozoic (mainly from Silurian to Permian, involving a little of the Early Triassic) plant data in South China, the evolution of terrestrial vascular plant diversity in the Paleozoic in southern China was revealed through comprehensive data analysis: Paleozoic (from Silurian to Permian) ) The diversity of terrestrial vascular plants showed an overall upward trend. In Silurian, the terrestrial vascular plants were in the earliest stages of evolution and their diversity was in the establishment stage. From Early Devonian to Early Carboniferous, the terrestrial vascular plants were differentiated and differentiated Stage, its ups and downs of diversity, rapid replacement of plant types is the fastest growing period of terrestrial vascular plant species, plants from the beginning to completely occupy different terrestrial ecosystems; from the early Permian, plant diversity rapidly And reached the peak of the Paleozoic plant diversity in the middle and late Permian.Comparison of the marine and terrestrial biodiversity in Late Paleozoic in South China shows that in the common earth ecosystem, the late Paleozoic dynamic and plant diversity of the South China Sea developed in coordination , Reflecting the diversity of marine and terrestrial ecosystem evolution of their own characteristics.F / F and Permian end of mass extinction event caused terrestrial vascular plant more The former is mainly characterized by a substantial decline in diversity during the Frasnian period, the latter in addition to the extreme decline in diversity, the plant group has undergone a fundamental change.
