Abstract

Based on the soil salt research data, combined with the hierarchical clustering method and geostatistics method, we analyzed the spatial variation characteristics of soil salinity of topsoil to reveal the degree and status of soil salinization in lower reaches of Heihe River. The soil salinity showed clear surface accumulation characteristics. The soil salinity and ions content have a strong variability, with the variation coefficient changing from 0.42 to 1.99. The main type of soil salinization in the lower reaches of Heihe River is chloride sulfate. The salinization is severe, and salinized soil proportion is as high as 42.87%. From the variation characteristics of soil salinity in the horizontal direction, we know that the soil salinity of topsoil has a strong spatial correlation. The optimal model of variation function is spherical model. Soil salinity was scatted in the study area. Overall, low soil salinity was distributed in the Ejina Oasis and along the river bed, and high salinity was distributed in West Juyan Lake and Gurinai area. From the variation characteristics of soil salinity in the vertical direction, we know that soil salinity profile in the study are can be divided into 4 types, in particular, surface accumulation profiles, equably distribution profiles, oscillation profiles, and bottom accumulation profiles.

Key words： soil salinity; hierarchical clustering method; geostatistics method; Heihe River
