    Abstract:

    Fifty soil samples were collected in Chaihe basin in October 2011,and the sampling locations were recorded by GPS.Traditional statistics and geostatistics based on ArcGIS were used to analyze the spatial distribution of soil salt and water-soluble Ca2+ and Mg2+.Results from traditional statistical analysis showed that surface soil salt,water-soluble Ca2+ and Mg2+ were exhibited as logarithmic normal distribution within the study area.The content of water-soluble Ca2+ and Mg2+,total soil organic matter,total nitrogen and total phosphorus has significant positive correlation with soil salt.The soil salinity and soil calcium ions showed strong mobility as there were more in the low-lying place.
