| 摘 要： | INTRODUCTIONVermicular red earth is distributed widely in South China,significant for the research into Quaternary environment andglobal change. Huang (1993) discovered the evidence of human activities-popple tools in vermicular red earth of the middle-upper reaches of Hanshui Riverl Zhu et al. (1991 ) statedthat red earth was a good information carrier of global changeafter the research into tropic red earth and environment byweathered mineral and geochemistry. Zhao and Yang (1995)stud…

| Abstract: | Phytolith analysis is employed in bioclimatic research into vermicular red earth, especially into its form, assemblage and zonation. The phytolith assemblage is divided into 10 zones. The statistics and main factor analysis of phytolith show that the obtained main factor load curves could suggest a climate change. Combined with phytolith assemblage feature, the bioclimatic variation of vermicular red earth during its formation stage, consisting of 5 arid-cold stages, 4 warm-humid stages and 2 mild stages, is reconstructed in detail. The research results indicate that phytolith records are ideal paleoclimatic signals in vermicular red earth, and that abundant information on environmental evolution can be located. |
