摘要
Pollen types identified from the Heqing deep drilling core were divided into different pollen ecological groups in this paper. The changes of seven pollen ecological groups, two palynological diversity indices (D-total and H’-total) and several high percentage pollen taxa are used to reconstruct the palaeoclimatic evolution of the Heqing Basin of Yunnan Province. During 2.780~2.729 Ma, 2.608~1.447 Ma and 0.342~0.118 Ma, the climate was dominate by relative warm and dry conditions, implying a rather weak southwest monsoon. oft-com:office:office" />
