Abstract:
Spatial and temporal changes in vegetation patterns of the Yinma River Basin were reconstructed using analysis of modern pollen-vegetation type relationships and a pollen core. This 4. 6 m alluvial section was collected Yanshen Port in Lulong county, Hebei province. Forest coverage in 11000-9000 aBP was about 10% and this increased to 20%-40% in 9000-4000 aBP. During 3000~2500 aBP the forest coverage decreased to 10%~20%. The large quantity of Picea and Abies pollen found about 9000 aBP, indicates that movement in the altitudinal zonation of vegetation occurred in Yinma River Basin at around this time.
