The study looked at the moisture content in layers of soil in Shaolingyuan, China. They found that the moisture content varied between loess layers and red paleosol layers. The amount of water in the soil changed from top to bottom, with fluctuations in moisture content and porosity. The researchers identified five water-bearing layers made of loess and water-resisting layers made of red paleosols. The properties of these layers were influenced by the climate when they formed, with the water-bearing layers developing in a cold-arid climate and the water-resisting layers forming in a warm-moist climate. Groundwater enrichment was found to be influenced by the well-developed water-bearing space in loess layers and the water-resisting characteristics of red paleosol layers.
