This research aims to investigate the fractal characteristics of soil particles and how they relate to soil properties in different forest stands in Liaoning Province.
Selected various forest types, including natural and plantation forests, in Qingyuan County as study sites.
Analyzed soil particle size composition, physicochemical properties, and fractal dimensions using treeless plots as controls.
Conducted multifractal analysis to assess spatial distribution and relationships between soil characteristics.
Soil particle size compositions in all forest stands were dominated by sand, with excellent sorting and narrow peaks.
Average particle size and single-fractal dimensions were significantly higher in forest stands compared to control plots.
A positive correlation exists between single-fractal dimension and clay/silt volume fractions, indicating soil quality improvement under forest protection.
Abstract
In this study, natural Pinus koraiensis Siebold thus, evaluating soil quality requires combining single- and multifractal dimensions to characterize physicochemical properties and particle size variation.
