Electrical conductivity method is a simple and rapid way to determine soil salinity, and it has been widely applied to modern soil, but limitedly applied to loess-paleosol sequence. In this paper, samples from Luochuan and Zhouyuan loess sections have been analyzed to measure the salinity by using electrical conductivity method. We focus on the impact of water-soil ratio and oscillation time on the determination, and the optimum conditions for conductivity determination of salinity in loess-paleosol sequence are identified on the basis of numerous experiments.
Key words： loess-paleosol; electrical conductivity; soluble salts; water-soil ratio
