资源简介：
关中盆地渭南地区十五万年来的黄土剖面记载了6个大的成壤期。全新世土壤S0是联合国土壤分类中的淋溶湿草原土。马兰黄土中包含两层古土壤，属典型黑钙土。S1古土壤由三层土壤复合组成，从上到下依次为典型黑钙土、淋溶湿草原土和深色淋溶土。成壤期与全球冰量较小的时期相对应，但古土壤的类型及发育程度与深海氧同位素所推测的全球冰量的变化有很大的不一致性，相反许多方面与北半球夏季太阳辐射的变化有较大的可比性。
The loess-paleosol sequence spanning the last 150,000 years in the Weinan area of the Guanzhong Basin documents six major pedogenic intervals. The Holocene soil S0 is categorized as Argillic Wet Grassland Soil per the United Nations Soil Classification System. The Malan Loess preserves two paleosol layers, which are classified as typical Chernozems. The S1 paleosol is a composite of three distinct soil horizons: from top to bottom, they are typical Chernozem, Argillic Wet Grassland Soil, and Dark Luvisol. These pedogenic intervals correspond to periods of relatively low global ice volume. However, the types and pedogenic development intensities of these paleosols exhibit significant inconsistency with the global ice volume variations inferred from deep-sea oxygen isotope records. Conversely, they show strong comparability with changes in Northern Hemisphere summer solar radiation across multiple aspects.
