Spatial variability of soil moisture and salinity in four typicalplant communities in the Ebinur Lake wetland was analyzed by traditional statistics and geo-statistics methods.The results indicate that:(1)Apart from the strong variability in the Phragmites community,soil moisture and salinity are of medium variation in the other plant communities;(2)With soil depth increasing,the variability of soil moisture in the Haloxylon ammodendron community and Halocnemum strohilaceum community shows no obvious change while that of Suaeda salsa community and Phragmites community goes declining.As for soil salinity,apart from the Haloxylon ammodendron community,the variability of soil salinity was reduced gradually from top to bottom in the other plant communities with the high salt content in the surface layer;(3)The spatial strut tural analysis shows that the distribution of soil moisture and salinity is well accorded to the Uaussian model in certain areas with strong spatial autocorrelation affected by climate condition,distance from the lake,area fluctuation of the lake and soil types of four plant communities;(4)As for the correlations of the soil moil ture and salinity among four kinds of plant communities,all correlations are relatively small,of which correlation between Suaeda salsa community and Phragmites community is positive,and that between Halocnemum strohilaceum community and Haloxylon ammodendron community was negative.The variabilities of soil moisture and salinity in the Suaeda salsa community and Phrahmites community are generally bigger than those in the Haloxylon ammodendron community distance from the lake adffected spatial variability and Halocnemum strobilaceum community showing that of soil moisture and salinity.
