| 摘要 | Sensitive changes in precipitation influence the stability of semiarid ecosystem, rain-fed agriculture, and densely populated society in northern monsoonal China (NC). However, shortage of regional-scale quantitative syntheses imposes restrictions on investigating long-term relationships among precipitation dynamics, possible climatic forces, and prehistoric demographic fluctuations. Herein, we contribute a regionally compiled anomaly record for Holocene annual mean precipitation (PANN) relative to its modern-day values in NC. The Holocene PANN variations in NC may be essentially determined by changing thermal gradients of continental land-ocean and west-east equatorial Pacific, profoundly affecting strength and location of West Pacific Subtropical High that may principally modulate intensity of East Asian summer monsoon and resultant rainfall in NC. Importantly, variation partitioning analysis quantitatively demonstrates that the overall changes of precipitation (43.3%) may play a more important role than temperature (3.2%) and their shared effects (0.8%) in independently accounting for long-term variation of regional-scale Holocene population fluctuations in NC. Plain Language Summary Quantitative inferences of regional-scale precipitation fluctuations on time spans longer than instrumental climatic records are requested to better predict long-term changes of East Asian summer monsoon that influences the lives of nearly one fourth of the total population in our world. Evaluating the possible role of large-scale climatic changes on affecting human population sizes of the distant past is a pressing concern and remains contentious. In this study, for the first time, we provide a regionally synthesized record of Holocene precipitation anomalies relative to present-day values for the monsoon-influenced northern China. This composite record has been demonstrated to be reliable as a representative for reflecting broad-scale precipitation variations across northern China. In addition, we first quantify the relative contribution from both precipitation and temperature on influencing the Holocene demographic changes in northern China. Our results suggest that precipitation may be more important compared with temperature when independently explaining the total variation in long-term prehistoric population patterns. |
