摘要
对平凉二道沟剖面二叠系山西组植物化石的特征、性质及其古生态学方面进行了分析研究。认为本区植物群的主要埋藏类型为原地埋藏,其次为亚原地埋藏,其化石群落基本能反映当时植物群的生活面貌。并根据植物群的特征分析,指出当时的环境为亚热带湿热近湖或临近滨浅海的低山丘陵区湿地浅水沼泽环境。
Based on studying on the plant characteristic of the Permian Shanxi formation in the Erdao Gou field section in Ping Liang area,the palaeoecology study on this flora has been analyzed.The major burial type was autochthonous,the following was hypautochthonous.The fossil community has been able to rebuild the life community.In addition,based on the study on the characteristic of the flora,the palaeoclimate of the early Permian in the study area has been turned out to be a shallow water marsh environment near the lake or sea of the sub-tropic.
