Soil shrinkage happens in the process of saturation to air dry, often accompanied by the phenomenon of surface subsidence and cracks. The measured variations in soil shrinkage of sugar cane, pear tree, soybean experimental plots in Guilin agricultural scientific academy were fitted by Soil Shrinkage Simulator software. The results showed that the SSS software which fitted the measured data well (r > 0.97) presented the "S" type shrinkage curve in 3 plots, however, the differences were also found in three conditions. The lower bulk density companying with larger total porosity, higher organic content and no-tillage method in pear tree plot which induced to the loose soil structure and higher soil moisture content, finally caused the largest degree of soil shrinkage. Anyway such phenomenon was not observed in sugar-cane and soybean plots, which was opposite to our hypothesis (the soil shrinkage was greater in sugar-cane plot than in soybean plot). On the one hand, furrow planting of sugar-cane plot increased bulk density of partially superficial soil; on the other hand, water stored in the furrow directly infiltrating into the subsoil rarely contributed to the surface soil moisture. Both of them resulted in soil shrinkage of sugar-cane was not obvious than soybean’s. In a conclusion, expect for the soil properties itself, the land-use management had a great influence on soil shrinkage.
