Glacial-interglacial changes in the distribution of C3/C4 vegetation on Chinese Loess Plateau have been related to East Asian summer monsoon intensity and position, could provide insights into future caused by global warming. Here, we present δ(13)C records bulk organic matter since Last Glacial Maximum (LGM) from 21 loess sections across Plateau. The values (range: -25‰ -16‰) increased gradually both LGM mid-Holocene each section northwest southeast time interval. During LGM, C4 biomass <5%...
Abstract A high-resolution pollen and Pediastrum record, spanning 12,500 yr, is presented for Lake Bayanchagan , southern Inner Mongolia. Individual taxa (PT-MAT) the PFT affinity scores (PFT-MAT) were used quantitative climatic reconstruction from algal data. Both techniques indicate that a cold dry climate, similar to of today, prevailed before 10,500 cal yr B.P. The wettest climate occurred between ∼10,500 6500 B.P., at which time annual precipitation was up 30–60% higher than today....
Summary China has been investing heavily in afforestation programmes to control soil erosion on the vast C hinese L oess P lateau ( CLP ). This massive led a considerable increase forest and decrease dust‐storm activity some areas. However, there have also negative outcomes, including low tree survival rate, increased erosion, exacerbated water shortages deep desiccation. One important explanation for these is use of inappropriate species because lack knowledge natural vegetation area, which...
Abstract The responses of the Indian and East Asian summer monsoons (ISM EASM) to warming since last deglaciation are controversial. Pollen results from a subalpine lake in ISM area show that Tsuga dumosa forest zone migrated at least 650 m upward during 18.6–7.1 kyr BP, indicating gradual rise mean annual temperature exceeding 3.9 °C. In response, grasses deciduous evergreen broad‐leaved trees successively colonized mountainous environment. By contrast, around EASM was gradually occupied by...
Carbon-based perovskite solar cells (C-PSCs) hold great prospects for commercialization due to their lower manufacturing cost and better stability when compared with metal electrode perovskite. Nevertheless, power conversion efficiency (PCE) is than those of metal-based because the inadequate interface contact between carbon layer. In this study, hole transport layer (HTL)-free carbon-based configuration utilized further reduce cost, methylammonium chloride (MACl) additive introduced...
&#160; A 39,000-year record of sedimentary environmental changes, based on high-resolution grain size and diatom records from core ZK13-22, in the eastern shore Dongzhaigang harbor, Hainan Island, make it possible to study relationship between changes area sea level South China Sea.&#160; The results show that during period 39.4 15.3 ka B.P., ZK13-22 sediments was relatively coarse, no diatoms were observed corresponding layer, suggesting mainly a terrestrial environment. Between...
The response of vegetation to past global warming, as revealed by geological records, can provide insights into future changes. We used pollen records reconstruct spatial changes in the boundary between steppe and forest/forest-steppe for Last Glacial Maximum (LGM), mid-Holocene, Interglacial (LIG), mid-Pliocene, representing major temperature. results showed that region east 110&#176; E, trend rotated anticlockwise around 30&#176;, 5&#176; 10&#176;, during warm periods LIG,...
Mountainous areas experience significant variations in temperature, humidity, and vegetation over short distances, thus mountain ecosystems are particularly sensitive to climate change. The Hengduan Mountains, located east of the Tibetan Plateau, characterized by a diverse terrain that includes plateau surfaces, alpines lake basins. In this study, we present two pollen records from cores Mountains. Core YL Lake Tianchi spans last 23 ka, while core XMLT-1 Ximenlongtan covers 9.4 ka.Around...

This study presents an method plant functional type (PFT‐MAT) which environmental proxies a moisture index (α, i.e. ratio actual evapotranspiration to potential evapotranspiration) are used constrain selection analogues.

Abstract. Sedimentary charcoal records are widely used to reconstruct regional changes in fire regimes through time the geological past. Existing global compilations not geographically comprehensive and do provide consistent metadata for all sites. Furthermore, age models provided these harmonised many based on older calibrations of radiocarbon ages. These issues limit use existing research into past regimes. Here, we present an expanded database records, accompanied by new recalibration...
To determine the timing and spatial distribution of mid‐Holocene drying over northern China, mineralogical oxygen isotopic composition authigenic carbonate from a closed lake at Bayanchagan, southern Inner Mongolia, were measured. Further analysis synthesis geological data performed. Results Lake Bayanchagan show significant 6000 calendar years (cal years) B.P., indicated by dolomite precipitation striking rise in δ 18 O values. The reveals zonal for China mid‐Holocene, which began 9000–7000...
