ABSTRACT

Through different water-soil ratio, oscillation time, ion contents and soil salt quantity, the correlation and regression between the whole soil salinity in oasis-desert ecotones in Tarim basin and electro conductivity of soil soak-out-liquid have been studied by electric conductivity methods. The results indicated: when water-soil ratio was 1:1-6:1, there was significantly correlation between electro conductibility and whole-salt quantity. But the 5:1 water-soil ratio is better according to the soil characteristic in this locality. After the oscillation time of soil samples was 10 minutes under the 5:1 water-soil ratio, the electro conductibility of soak-out-liquid there was not marked difference. The correlation between ion of comparative large contents and the electro conductibility soak-out liquid was very marked. When soil salinity is large, linear functions can be used to better measure the whole salt quantity of this local by subsection analysis.
