Abstract:
The 0-20 cm surface soil nutrients in Xilingol grassland were used as test marerial.The field sampling and laboratory experiments were carried out，the characteristics and spatial variability of the soil nutrients were studied by classical statistics，geostatistics，spatial autocorrelation analysis and GIS technology,in order to provide reference for grassland ecological environment protection and sustainable utilization of soil resources.The results showed that,1) SOC content was deficient，TN content was abundant and TP content was extremely scarce in Xilingol grassland.The variation of soil C，N，P and their stoichiometric ratios were moderate.2) In Xilingol grassland,SOC，TN，TP，C/P and C/N had strong spatial variability，which was mainly caused by structural factors.N/P was a medium spatial variation，which was mainly caused by random factors and structural factors.3) SOC，TN and the global ecostoichiometric Moran′s I were positive in Xilingol grassland，belonging to the cluster distribution type，while TP belonged to the isolated distribution type.4) The horizontal spatial distribution of SOC，TN，C/N，C/P and N/P in the 0-20 cm soil layer of Xilingol grassland showed a zonal distribution，gradually decreasing from east to west，and the spatial distribution of TP was not significantly different.5) Except that soil TP had no significant correlation with C/N and C/P，the other indexes had significant or extremely significant correlation characteristics.
