Abstract: | Material in field investigation and experiment shows that four paleolsols developed during Holocene in Lintong .The two paleosols among them developed in warm-moist climate, other two paleosols did in cold-arid climate .The soils developed in warm-moist climate are Brown forest soil and leaching Cinnamon soil , the soils developed in cold-arid climate are Connamon soil and clay grouting Dark loessia soil . Microtexture and particle size of Holocene soils in Lintong and Chang'an area indicate that the climate became arid gradually in Xi'an region since Holocene climatic optimum . |
