Abstract Soil organic matter (SOM) plays an important role in improving soil fertility and crop productivity, and studying its spatial variability can provide a scientific basis for targeted fertilization and sustainable land use and management. This paper selected Changji Prefecture of Xinjiang as the study area, and used three-stage SOM data (the second soil survey, 2010 and 2018) to calculate the generalized dimension spectrum D(q), multifractal singularity index ɑ(q) and the multifractal spectrum function f(ɑ(q)) based on the multifractal method to explore the dynamic changes of SOM spatial variability. The results showed that: (1) The average SOM contents in the three periods were 10.46, 16.69 and 18.16 g/kg, respectively, showing an upward trend. However, the SOM contents of all counties were lower than the national average level (24.30 g/kg) in 2018. (2) The spatial distribution of SOM in Changji Prefecture had non-uniform multifractal characteristics from the second soil survey to 2018. The distribution range of SOM value gradually became narrowed, and the spatial distribution variability decreased, tending to be uniform. The degree of SOM spatial variability in Fukang city, Jimusaer county, and Mulei Kazakh autonomous county increased slightly from 2010 to 2018. (3) In 2018, the spatial distribution range of SOM widened from west to east, with an increasing variation degree, and internal differences became larger, tending to be non-uniform. (4) In the three periods, all the low-value data had a greater variability, with the variation degree being higher than that of the high-value data. Fukang and Mulei were dominated by the high-value data in 2018. Long-term farming had increased the SOM content, and the spatial distribution gradually tended to be uniform. However, there was obvious spatial heterogeneity of SOM. It is necessary to adopt targeted approaches to improve overall soil fertility in different parts of the study area. It is recommended to promote targeted fertilization and to improve irrigation and farming measures in the places with high spatial variability of organic matter, such as Fukang, Jimusaer and Mulei.
