Abstract—Effective improvement of saline-alkali soil is very significant for the yield and the ecological environment, thus accurate parameters of different saline-alkali soils are deeply required. In this paper, the areas and perimeters of different soil cracks are detected in a non-contact, non-invasive online way by the three-dimensional laser imaging technology and several common texture feature measures are also derived from GLCMs of different soil crack images. Then the regression analysis among soil crack characteristics, soil conductivity, soil soluble sodium and SOM is studied and the result is very satisfactory which means soil conductivity, soil soluble sodium and SOM of saline soil can be referred very well through this method with the soil crack parameters.

Key words—saline-alkali soil, soil crack, soil conductivity, soluble sodium, SOM.
