Determination of soil texture is affected by various factors and ought to adopt a method of comprehensive fuzzy evaluation. Based on Kaczynski soil classification standard and ridge-type subordinate function,texture type of 4 Holocene loess profiles with 30 layers in the Guanzhong region was determined by applying synthetically decided method of weighting average. Results indicated that texture types of Malan loess (L₁)，illuvial horizon (Ck)，and Holocene loess (L₀) are identical and thus，do not have the significance of instruction. However,Holocene paleo sol (S₀)，airslake andleaching loess (C₁)，and modern topsoil(Ts) are difEerent.From east to west,soil texture types of So and G change from heavy loam soil,medium textured soil,to light textured soil. The change of topsoil(Ts) is indeterminacy because it is obviously affected by the human activities.
