Soil particle-size distribution is one of the most important physical attributes due to its strong influence on soil properties related to water movement,productivity and soil erosion.The monofractal and multifractal characteristics of soil particles and their correlation with soil organic matter(SOM) under different land use patterns in lowlands of the Yellow River Delta were studied with the monofractal and multifractal theory and methods.The results showed that the monofractal dimension D of different la...
