Analysis and Forecast of Volume Fractal Dimension of Soil Particle-size Distribution in Yangling of Shaanxi
Abstract:Based on soil particle volume distribution,the paper studied relationship between volume fractal dimension of soil particle-size distribution and soil physical properties,and established its estimation function.The results showed that average values of volume fractal dimension of soil particle-size distribution in 0~20 cm and 20~40 cm soil layers were respectively 2.649 1 and 2.626 2 in Yangling;correlation between volume fractal dimension of soil particle-size distribution in 0~20 cm and 20~40 cm soil layers and clay content was most significant,and correlation between them and sand content took second place;relative error of forecasted volume fractal dimension of soil particle-size distribution in 0~20 cm soil layers was between-0.298% and 0.726%,the one in 0~20 cm soil layers was from-0.179% to 0.772%,which illustrated that forecasting precision of established model was very high.
