Abstract:Soil nutrients are the foundation of soil fertility, and it is of great significance in the science of fertilization to master soil nutrient content and distribution characteristics. Therefore, we used ArcGIS technology and correlation analysis to evaluate the spatial distribution rule of the primary soil nutrients in Jinzhong city, Shanxi Province, and its relationship with the type of land. The results showed the following:(1)The mean pH of Jinzhong city soil was 7.97,and all of the soil was alkaline; the nutrient contents of soil varied greatly across counties.(2) The average contents of SOM,TN,TP, and TK in the study area were1.42%,0.08%,0.07%, and 1.97%, respectively. According to the second national soil survey of nutrient classification standards, the surface soil SOM, TN, and TP contents in Jinzhong were low, and the average levels were level four, level four, and level five respectively; however, the TK content was high with an average of level three.(3) With an increase in altitude, the average content of soil SOM increased first and then decreased, the average content of TN significantly increased, and there were no obvious trends in the changes of soil TP or TK.(4) Land-use type and soil nutrient correlation analysis showed that at altitudes of 733-1500 m, SOM,TN, and TP contents were significantly higher than their averages in unused cultivated land and nature reserves, and average TK content was significantly lower than that in other land-use types; the average contents of SOM,TN, and TP in the cultivated land above 1500 m were lower than those of other land types. Within the elevation range covered by the sample points, elevation was significantly correlated with TN content, but the correlations between elevation and SOM,TP, and TK were not significant.
