Abstract
Spatial variability in conductivity of the coastal saline soils was analyzed using geostatistics Semivariance function and their diagrams were used The results showed that spatial variability in soil conductivity was composed of system and stochastic spatial variabilities Environmental factors such as microrelief, soil management have influence on system variability, so different plot has different system variability structure, and system variability of surface layers was stronger than that of sub layers It was also found that stochastic spatial variability structure was very stable in different plots and has component construction, the smallest limit distance was about 2 0 m, the next limit distance was about 6 0 m in this experiment, and those limit distances were not influenced by directions of sample sites and experimental time
