Abstract

Abstract:

Clarifying the spatial variability of soil salinity is the aim of soil salinization research and saline-alkali land improvements. In this study, the Minqin Basin in the lower reaches of the Shiyang River in the arid inland river basin was selected as the study area. By analyzing the statistical characteristics, spatial autocorrelation, variability, and distribution patterns of soil salinity in situ data of the 0-30 cm soil layer, the changes in the spatial heterogeneity of soil salinity could be explored to provide a theoretical basis for soil salinity in the study area. The measured soil salinity content and its variation range both decreased as the soil layer increased, and both were in a skewed normal distribution. Moran’s I index showed a “∽” type fluctuation trend, and the range of values increased with the soil layer, and the positive (negative) spatial autocorrelation decreased as the distance increased (negative spatial autocorrelation of 0-10 cm was opposite). The exponential model was the most suitable for use with the variogram. The R² increased with soil depth (0.62→0.69→0.81), and the RSS was 0.0002. Variation rules of C₀/(C₀+C) and A₀ were consistent, and the spatial heterogeneity ranged from weak to strong to moderate with soil depth. Accuracy of the interpolation was 10-20 cm > 20-30 cm > 0-10 cm. The soil salinity of the three layers had spatial differentiation characteristics, and the degree of salinization increased gradually from southwest to northeast in the horizontal direction (the same soil layer). In the vertical direction (different soil layers), the distribution patterns changed from simple to complex, and gradually tended to patches (10-20 cm) and spots (20-30 cm) from the aggregation state (0-10 cm). Nonsalinized soil (<1.50%) and four different levels of saline soil were distributed in the three soil layers, and the area of saline soil was moderate (>70.00%) > strength (approximately 20.00%) > mild (approximately 9.00%) > saline soil (<0.50 %).

Key words: soil salinity, spatial variation, geostatistics, Minqin Basin, downstrearm of Shiyang River
