Discussion about correlation distance of loess parameter

[摘要] The correlation distance of soil parameter is a basic indicator which use to descript the spatial variability and autocorrelation of soil. It is of great significance to study the rule of its change with different calculate methods and test samples. Based on the Xi'an loess, the problem of data collection which used to set up the soil random field model was discussed in this paper. Using borehole CPT data as samples, correlation distance of different loess layers were calculated. The differences of correlation distance like between with different method and different indexes was discussed, And questions some the change law of this difference with the space H was discussed.
