Abstract: We put great importance to research of leaching behavior of elements in soil science and aeolian sedimentary geochemistry. However, the present study is limited to the level of qualitative description, at the same time, there are many mistakes in the methods and parameters. This paper mainly analyzes the microcosmic process of chemical leaching. we hold the view that it is Logarithmic between the atmospheric precipitation and the poured out elements in liquid. Futhermore, the exact function relation is given. The experimental result of the soil soaking, centrifuging and ion chromatography using the soil surrounding Lanzhou city, also proved the function relation is established. Additionally, we obtained the methods how do a quantitative representation of elements leaching properties by using leaching coefficient η or λ. It may have a important significance on the research of the assessment of soil fertility maintenance capability and aeolian deposition-geochemistry
