摘　　要：文章通过对现有相关资料的分析 ,支持在华南地区末次冰盛期时热带植被消失 ,地带性植被为亚热带常绿阔叶林的观点 ,但认为在末次冰盛期时该区存在“温带草原”的说法欠妥。认为无论是以蒿属占优势还是以禾草为主的草本植物群落 ,都是由于局部环境的改变所致 ,与气候变化无直接关系 。The vegetation types during the Last Glacial Maximum in South China were assessed in the paper using the relevant data available. The present authors agree with the viewpoint that the tropical vegetation in South China disappeared during the LGM and the regional vegetation with latitudinal distribution was subtropical evergreen broad leaved forest in nature, but disagree with the statement that advocates the occurrence of 'temperate steppes' in those areas during the LGM. The 'herbaceous communities' dominated by either Artemisia or Gramineae were actually resulted from local environment rather than climatic changes and can not be taken as the representatives of regional vegetation. It is suggested that the south boundary for steppe in the LGM was situated in the present north bounds of the middle subtropics, approximately equal to the southernmost distribution of the Xiashu Loess in China.
