Late Holocene vegetation succession and climate change in the Central Plains of China: Evidence from a high-resolution pollen record
AbsractChanges in the East Asian summer monsoon precipitation will have a significant impact on China’s politics, economy, and social development. To explore the controls and drivers of the Late Holocene (~3350–2560 cal. yr. BP) vegetation succession and East Asian summer monsoon precipitation changes in the Central Plains of China, we conducted pollen analysis of the Pu Tian core collected from ...

Mid-Holocene hydroclimatic changes drove Neolithic agricultural development in the Luoyang Basin of the Central Plains
全新世中期的水文气候变化促进了洛阳盆地新石器时代农业发展 摘要：农业在历史上不仅是社会发展的经济基础，也是连接气候变化与人类活动的重要纽带。研究农业与气候变化之间的关系，有助于深入理解古代社会动荡的成因。中国中原地区的洛阳盆地是中华文明的重要发源地之一，然而，关于该地区新石器时代农业实践与气候变化之间是否存在关联，目前尚不明确。本研究采用花粉数据作为区域水文气候和农业活动变化的代用指标，对距今约8000至3890年期间的环境与农业演变进行了分析。...

Precipitation variations around ~4.2 ka BP in the Luoyang Basin: Apollen-based quantitative reconstruction
基于孢粉的洛阳盆地~4.2 ka BP降水变化定量重建 4.2 ka BP气候事件作为全新世一次关键的千年尺度气候突变事件，对全球古文明的演化进程产生了深远影响，尤其与多个古代文明的衰落密切相关。然而，中国中原地区的史前文明却在该时期表现出显著的连续性与发展韧性。本文聚焦于中原核心区域的洛阳盆地，基于HZ-1剖面高分辨率花粉组合分析，结合17个AMS ¹⁴C测年数据，并综合运用植被群区化方法（BIOME）与加权平均偏最小二乘法（WA-PLS）...

Early-onset of rapid deposition rates of the Mangshan loess challenges the classical hypothesis of full Yellow River connection during the late Pleistocene
AbstractUnderstanding the origin and evolution of the Yellow River is not only crucial for understanding the geomorphic and climatic history, but also pivotal due to its historical significance and ecological impact on China's environment. However, the timing of the full connection of the Yellow River, as a critical event in the genesis of this major river system, is still debated continuously. Among ...

2024-Pollen-based quantitative reconstructions of Holocene climate at Gun Nuur in N Mongolian Plateau
AbstractThis study quantitatively reconstructs Holocene climate based on a palynological analysis of a 745-cm lake core at Gun Nuur in the northern Mongolian Plateau. The core is precisely dated with 49 dates and the dataset comprises 372 pollen samples providing high temporal resolution. We obtained quantitative reconstructions of annual temperature (Tann) and precipitation (Pann) based on com...
