摘要:

全新世环境演变研究是过去全球变化研究的重点,也是当今全球变化研究的重点和热点。深入了解和研讨全新世成壤环境演变和沙尘暴活动对于丰富全新世环境变迁理论、认识现阶段的沙尘暴活动,促使人与自然环境协调发展都有着十分重要的意义。通过研究关中平原中西部地区全新世地层中粒度、磁化率、CaCO3和pH值四项指标,综合分析了本区全新世11 500—3 100 a BP期间的成壤环境演变及与之相关的沙尘暴活动信息。

Abstract: Holocene environmental change was the focus of global change research in the past, still is the key and hotspot of present global research. To deeply understand the Holocene environmental change of pedogenesis and sandstorm activity has very important significance in enriching the theory of Holocene environmental change, realizing the sandstorm activities at present, and making people and nature develop harmoniously. Taking the midwest of Guanzhong plain as study region and through studying on the four climate proxies: grain size, magnetic susceptibility, CaCO3 content and pH value, the paper synthetically analyzed its pedogenesis environmental change and the related sandstorms references during 11 500—3 100 a BP.

Key words: Holocene, midwest of Guanzhong plain, loess-paleosol sequence, sandstorm activity, pedogenesis process
