Tree‐Ring Insights Into Past and Future Streamflow Variations in Beijing, Northern China

Water Resources Research, Год журнала: 2025, Номер 61(1)

Опубликована: Янв. 1, 2025

Abstract As the largest city in northern China and capital of China, rapid increases Beijing’s water consumption recent years have made resources provision an increasing problem. To rationally allocate resources, it is important to obtain long‐term runoff information Beijing. In this study we develop a 236‐year chronology tree‐ring widths based on cores from Pinus tabuliformis four sampling sites. The resulting regression model reconstructs December–July Yongding River Beijing, with 49.5% variance explained, back 1786 CE. Among last 236 years, 1868, 1956, 1991, 1998, 2018, 2021 were extremely high years; 1900, 1906, 1999, 2000 low years. Comparison reconstruction results climate grid data demonstrated large magnitude change North during period. Linkage analysis between reconstructed large‐scale vapor indicated that occurred negative phases Pacific Decadal Oscillation, which may be influenced by East Asian Summer Monsoon. Projections indicate flow will increase future. Supported policies such as Ecological Water Supply South‐to‐North Diversion, regional vegetation productivity increased substantially since 2000. Vegetation growth interacts volume. It unclear how long these continue.

Abstract Central Asia (CA), a typical arid and semiarid region, has experienced worsening droughts, adversely impacting agricultural production socioeconomic development. However, the evolution of hydrological droughts in CA remains unclear. Here, we used instrumental streamflow reanalysis to demonstrate decline surface runoff since 1990s, with 44.6% 33.2% area dominated by reductions snowmelt precipitation, respectively. We found that global warming contributes long‐term decrease runoff, while short‐term fluctuations are caused El Niño‐Southern Oscillation, such as southern drying induced decreasing precipitation during La Niña. project future drought characteristics based on state‐of‐the‐art simulations increasing duration severity CA, especially Amu Darya basin, Caspian Sea East Coast basin. These exacerbated higher anthropogenic emissions, posing high‐level risks 39.01% land 35.9% human population under an extremely high emissions scenario. findings highlight need for improved water conservation technologies concerted development strategies should be considered national policy makers this water‐scarce climatically sensitive region.

Late Ming Dynasty weak monsoon induced a harmonized megadrought across north-to-south China

Historians and paleoclimatologists have long studied the connection between ecoclimatic changes empire growth, transformation, decline, but striking cases remain rare. Here, we introduce a tree-ring chronology from southern China to reconstruct in April-to-November water balance of middle reaches Yangtze River over last 464 years. The reconstruction supports quantitative assessment spatiotemporal structure late Ming megadrought potential effects on subsequent dynastic transitions. Our results indicate that 1625 – 1644 CE occurred both northern parts East Asian monsoon region China. However, variations onset, duration, magnitude this event differ regions. combination factors such as Pacific sea surface temperature anomalies, weakened solar activity, large-scale volcanic eruptions may contributed occurrence megadrought. These are also identified key drivers interannual decadal fluctuations drought River. provides an historical context for development adaptive measures mitigate future impacts region. across north-to-south China, lasting 1625-1644 CE, was influenced by eruptions, according River's using chronology.
