Distribution characteristics and indicative significance of grain size and elemental content in surface-sediments of Qinghai Lake， Northeastern Tibetan Plateau

引用

Journal of Earth Science 2024年

作者： Yuqi Cheng Haicheng Wei Ronglei Duan shun wang Zhixiang wang Hongyu Li Fangming Zeng Yilin Hou Hongpan Xue Key Laboratory of Green and High-end Utilization of Salt Lake Resources， Qinghai Institute of Salt Lakes， Chinese Academy of Sciences Qinghai Provincial Key Laboratory of Geology and Environment of Salt Lakes Qinghai Institute of Salt Lakes， Chinese Academy of Sciences University of Chinese Academy of Sciences

Qinghai Lake in the northeastern Qinghai-Tibet Plateau (QTP)， being sensitive to paleoclimate change and anthropogenic activities， has attracted much attention from paleoenvironmental researchers. Grain size and elemental content in lake sediments are indispensable proxies for reconstructing paleoclimate and paleoenvironment. However， limited research on grain size and elemental content of surface-sediments in Qinghai Lake complicates decoding the information from lacustrine sedimentary strata. In this study， 55 surface-sediment samples were collected for grain size and elemental content analysis， combined with grain size end-member modeling algorithm (EMMA)， correlation (CA) and principal component (PCA) analysis to explore the controlling mechanisms and their environmental indications. Our results show that the hydrodynamic condition controls the distribution of surface-sediments in Qinghai Lake: exhibiting a belt-like pattern of sand-silt-clay， the clockwise circulation in the northwestern and southwestern lake transports sand to the two primary sedimentary centers. Three primary components representing different transport/depositional processes were separated: ‘lacustro-aeolian’， ‘fluvio-aeolian’ and river-transported bedload. Grain size controls the elemental content， particularly in terrestrial particles. Nitrogen (N) and phosphorus (P)， mainly derived from endogenous organic matter (OM)， tend to be absorbed by finer particles. The hydrodynamic conditions and anthropogenic activities also influence their spatial distribution. The chemical weathering index (CIA)， indicating a cold and dry climate， is highly related to grain size. This research provides crucial modern process references for accurately interpreting grain size and element records in sediment cores from Qinghai Lake.

针对GPT3模型在模拟大气剖面时存在精度不足的问题,在剖析其垂直修正方法的基础上,通过引入新的温度递减率和气压垂直改正算法,提出一种改进的GPT3模型,即GPT3v模型,并使用探空资料、NCEP再分析资料和GNSS数据验证新模型的精度。结果表明,垂直方向上GPT3v模型估计的温度、气压、天顶总延迟平均RMSE分别为6.0 K、7.9 hPa和23.0 mm,相比于GPT3模型的11.1 K、19.0 hPa和47.8 mm,精度分别提高46%、58%和52%。而当IGS测站与其周围4个模型格网点存在较大高差时,GPT3模型会存在较大的对流层延迟估计误差,GPT3v模型则能较好地解决这一问题。相较于GPT3模型,GPT3v模型在高空以及地形复杂区域具有更好的应用效果。
