Climatic changes in southeastern Transbaikalia in the Middle and Late Holocene and their influence on alluvial sedimentation environments are reconstructed from the results of study of the Ilya floodplain sediments (Alkhanai National Park). At the beginning of the Subboreal period, the regional climate became more arid, which led to a significant increase in steppe species communities in the landscapes. Intense climate aridization also took place at the beginning and at the end of the Subatlantic period of the Holocene. The alluvial-sedimentation rate increased during the weakening of aridization and decreased during cooling and the intensification of aridization. The obtained regional data are compared with data on the adjacent areas and the global climatic changes in the Northern Hemisphere. 相似文献

The evolution stages of the lacustrine-boggy sedimentary environments and the role of the climatic and volcanic factors were reconstructed on the basis of complex stratigraphic (botanical, palynological, and diatom analyses and tephrostratigraphy) and radiocarbon studies of the peat lands on Rasshua Island during the middle-late Holocene. The stages of the landscape evolution and the time of their reorganization were determined. 相似文献

Data of spore-pollen analysis and radiocarbon dating on soil profiles have been used in reconstructing the development stages
of meadow landscapes of Southern Kurils (Kunashir and Iturup Islands, and the Lesser Kuril Chain). The emergence of meadows
is due both to anthropogenic impacts and to a cooling in the Late Holocene (the last 1.5–2 thousand years ago). In the southern
part of the Lesser Kuril Chain, meadows landscapes have been of widespread occurrence during the last 4–6 thousand years.
The fallout of volcanic ashes differing in chemical composition and, in some cases, the entry of aeolian sand altered the
soil properties and had a dramatic effect on plant associations. 相似文献

The results of the complex study of a Holocene peat bog in the southern part of Ketoi Island, which is proposed to serve as
a reference section for the Central Kuriles, are discussed. The peat bog’s stratigraphy is based on botanic, palynological,
and diatom data, 16 radiocarbon age determinations, and the composition of the volcanic ashes. The peat accumulation initiated
approximately 6500 years ago. The successive changes of the island’s vegetation are traced through the Middle-Late Holocene
with defining of the phases of its development and dating the paleolandscape transformations related to the climatic oscillations
and volcanic eruptions. 相似文献

New data on the evolution of Lake Khanka and the formation of onshore bars at its western coast in the late Holocene are discussed in the paper. The late Subatlantic age of the bars and climatic conditions of their formation have been established. In the middle Holocene (SA II), the climate was warm and Lake Khanka was in the transgressive phase. Its level was 0.8–1 m higher than at present. At the end of the Subatlantic period (SA III), when the climatic conditions were cooler, regression of the lake began and continues up to now. The spore-pollen samples of different genesis taken near the studied section were examined for the more reliable interpretation of paleoclimatic events. 相似文献

The response of landscape biotic components of the western slope of the Sikhote-Alin Mountains (Bikin River middle flow) to the Middle–Late Holocene climate changes is discussed. The paleoreconstruction object was the Krasny Yar mari, which developed under the control of multidirectional short-term climatic changes. The last millennium was marked by particularly rapid and frequent changes in the local landscapes. The closely spaced orographic barrier strongly affected the development of biotic components and changes in the swamp hydrological regime. The moisture dynamics within the river catchment considerably controlled the development and change of the peat-forming plants. Several stages of the mari development were reconstructed; each began from the accumulation of eutrophic peat. It was followed by the transitional eutrophic–mesotrophic stage, with a higher role of atmospheric supply. The larch forests appeared in this part of the valley within the Atlantic–Subboreal cooling period. Korean pine developed in the forest vegetation in the low mountain relief at the beginning of the Subboreal and became one of the leading trees ~2.6–2.3 ka BP. The lower role of the Korean pine and birch forest expansion in the first half of the Subatlantic could be related to the fires. The broadleaf–Korean pine forests became widespread in the Medieval Warm Period. Local swamp landscapes changed dramatically in the Little Ice Age, while the slope vegetation was not subject to any major changes. The landscapes were also affected by the fires, which became more frequent. The derivative communities with birch appeared on the mari. Moreover, this part of the valley was occasionally subject to heavy flooding. 相似文献

An analysis is made of the changes in biotic components of landscapes during the Holocene Little Climatic Optimum on the island and mainland shores of the southern Far East which manifested themselves in all landscape zones. Some paleoclimatic parameters and the shift of landscape zones have been assessed. 相似文献
