- Abstract
The Altay Mountains in China comprise an complete natural geographical complex. Its vertical zonation of natural geographical elements is significant and influences pollen transportation, deposition, and preservation. Based on the analysis of the pollen assemblages of 53 surface samples from the western Altay Mountains and species investigations in plant communities, the relationship between surface pollen and modern vegetation distribution in this region was determined using cluster and principal component analysis. The results showed that (1) The pollen assemblages in the surface soil of the western Altay Mountains were consistent with the distribution of modern vegetation, with unique pollen assemblages in each vegetation zone. Artemisia - Chenopodiaceae - Poaceae - Ephedra, Poaceae - Artemisia - Rosaceae - Chenopodiaceae, Picea (Picea + Abies) - Betula - Rosaceae - Poaceae - Cyperaceae, Betula - Poaceae - Salix - Cyperaceae, and Labiatae - Poaceae - Betula - Rosaceae - Cyperaceae pollen assemblages dominated the desert steppe, steppe scrub, mountain forest, subalpine shrub, and alpine meadow vegetation zones, respectively. Cluster analysis identified each vegetation zone accurately, and principal component analysis showed that humidity was the primary factor that controlled their distribution. (2) Picea, Abies, Rosaceae, Betula, Salix, Leguminosae, Ephedra, Poaceae, Artemisia, Chenopodiaceae, Compositae, Labiatae, Cyperaceae, and Thalictrum were the main pollen types in the western Altay Mountains, Picea and Betula were representative of this area, while Poaceae, Abies, and Cyperaceae were less. Chenopodiaceae and Artemisia were strongly representative. In addition to its own factors, pollen content may also be related to preservation conditions.
