摘　　要：在综合研究了贺兰山北段晚石炭世晚期和早二叠世早期植物群的特征和性质的基础上 ,对此植物群进行了古生态学方面的分析研究。采用了传统的埋藏学研究模式 ,对不同地区植物化石分别进行了埋藏学的研究 ,得出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 ,有极少量为异地埋藏。其化石群落基本能反映当时植物群的生活面貌 ,再结合分异度的数据恢复了古群落。此外 ,根据植物群的特征分析 。On the basis of the study on the flora characteristic of the late Late Carboniferous and early Early Permian in the Helan Mountains, the palaeoecology study on this flora has been analyzed. The major burial type is autochonous, the following is hypautochthonous burial and the third is allochonous burial. The fossil community has been able to rebuid the life community. In addition, based on the study on the characteristic of the flora, the palaeoclimate of late Late Carboniferous and early Early Permian in the study area has been turned out to be a tropical climate of a lower latitude.
