- Abstract:
- The fractal characteristics of soil particles and their influencing factors in different community types in the surrounding area of the Xilamuren grassland were studied in order to provide a basis for the reduction of soil wind erosion and grassland degradation in desert steppe. Using the principle of soil particle size mass distribution and fractal theory to of desert steppe, the fractal dimension, particle size composition and hydrophysical parameters of soil particles of six 16-year enclosed communities of Allium mongolicum, Convoloulus ammannii, Stipa krylovii, Leymus chimensis, Koeleria glauca, Stipa brevii were determined to investigate the fractal characteristics and influencing factors of soil particles in different conmunity types und the near-natural recovery. The results showed that:(1)the fractal dimension of soil particles in this area mainly depended on the percentages of silt and very fine sand, followed by the percentage of fine sand, and the influence of other grain-level soil particles was little; fractal dimension of soil particles was significantly positively correlated with soil total porosity, capillary porosity, saturated water storage capacity and water storage capacity, and had little correlation with soil bulk density, non-capillary porosity, and retained water storage;(2)the maximum fractal dimension of soil particles in 6 different communities was 2.840, and the minimum value was 2.490, the average fractal dimensions of soil particles in 0—30 cm soil laver varied between 2.575 and 2.750, the average fractal dimensions of soil particles decreased in the order: Stipa krylovii>Stipa brevii>Koeleria glauca>Convoloulus ammannii>Allium mongolicum>Leymus chimensis; the fractal dimensions of soil fractals of six different community types varied with the depth of soil sampling, and showed a linear decline trend with increase of soil depth;(3)fractal dimension can be used as a comprehensive index to measure the degree of soil structure and restoration of grassland degradation. According to the fractal dimension of soil particles and its water storage performance, the improved soil characteristics and water storage functions of communities of Stipa krylovii, Stipa brevii and Koeleria glauca are superior to those of the other communities.
