摘要

Abstract

This study explores the effects of different vegetation restoration modes on shallow soil during sandy land management in the treatment area.It also investigates the different shallow-soil particle sizes under different vegetation restoration modes,providing a theoretical basis along with scientific and technological support for the restoration of mobile sandy land.The mechanical composition of soil samples was determined using a laser-parti-cle size analyzer and the particle size parameters—average particle size,standard deviation,skewness,kurtosis,and fractal dimension—were determined.It was found that(1)the soil in the study area is dominated by medium sand and fine sand,and the sand content can be reduced in each vegetation restoration mode,most prominently in tree shrub mode(where the decrease reached 11.53%).(2)The sample plot exhibited a high soil fractal dimension(2.30-2.52),which was mainly influenced by the silt and clay content.(3)The soil fractal dimension was highest(2.52)in tree shrub mode,where the average particle size was 18.18%lower than that in flowing sand and the sortability and kurtosis parameters were most optimal.The multi-level vertical structure of tree shrub grass more effectively intercepts the wind and sand and better retains the fine particles than the other restoration modes.Therefore,considering ecological function and sustainability,shrub grass is the preferred choice for vegetation restoration in this area.
