摘    要:通过对中纬区完全孢粉植被动态组合规律的分析,可以推导出某一地区沉积剖面中第四纪冷暖气候旋回的孢粉植被动态组合,其方式是:冷期孢粉动态组合,以比该区更北(平原)或更高位(山地)的孢粉植被为中间层,其上下依次对称出现比中间层更南(平原)或更低位(山地)的孢粉植被组合;暖期孢粉植被动态组合,以比该区更南(平原)或更低位(山地)的孢粉植被为中间层,其上下依次对称出现比中间层更北(平原)或更高位(山地)孢粉植被组合。

关 键 词:第四纪  古气候旋回  孢粉  孢粉植被动态组合  中间层

Abstract:According to the analysis the all sporo-pollen paleovegetation dynamical association in medial latitude area, a . general sporo-pollen paleovegetation dynamical association mode to cold-warm paleoclimate cycle in Quaternary Period at a certain section can be drawn as follows; A sporo-pollen paleovegetation dynamical association in cold period consists of such parts: the middle bed where sporo-pollen paleovegetation association is that of farther north in 1atitndo(on plains)or still higher in level (in mountains) than the section above and below which are beds of sporo-pollen associations which are farther south in latitude (on plains) or even lower in level (in mountains) than in the middle bed, successively and symmctr.ically displ.y on both sides of the middle bed. A sporo-pollen paleovegetation dynamical association in warm period consists of such parts: the middle bed where sporo-pollen paleovegetation dynamical association is farther south in latitude (on plains) or even lower in level (in mountains) than the section, above and below which are beds of sporo-pollen associations which are farther north in latitude (on plains) or still higher in level (in mountains) than in the middle bed, succesively and symmetrically display on both sides of the middle bed.
Keywords:Quaternary Period    paleoclimate cycle  sporo-pollen  a sporo-pollen paleovegetation dynamical association  middle bed
