on the basis of materials grain size analysis，CaCO3 content and microstructure determination of the soil sample from Tianjia village profile in Lantian, Sifu village profile in Chang'an and Yongchuan profile in Qishan, we know that the soil S0 developed in the middle Holocene had obvious illuvial clay grouting characteristics. The S0 has the typical characteristics of soil profile under the recent depositional break hiatus. At least, a part of its parent matter was mainly from L1 which was reconstructed by the soilforming action. The S0 clay grouting type in Guanzhong Plain not only to be possible to indicate the characteristics of local biological climate environment and little activity of sanddust storm, but also to indicate the remote correlation of environmental variation in thousand scale between this area and the northwest desert area. But the L0 developed in the later Holocene was soil in narrow sense and had the obvious sedentary grouting characteristics or sedentary—illuvial clay grouting characteristics, it developed in the process of continuous sediment of sanddust storm, and formed the thick clay grouting layer which developed weakly, the thick CaCO3 illuvial layer which distributed evenly. The profdile characteristics of the Holocene L0 indicate that soils developed under continuous deposit process of sanddust storm, there are no obvious horizons in the soil profile and soil thickness can be much larger than 2 m. There was the remote correlation of the climate between Guanzhong Plain and the northwest desert area during development of L0.
