Soil salt condition is the result of geochemical cycle under the natural physical geographical background, which natural factors together with artificial activity restricted the salt characteristics of ecosystem. Soil salt of oasis system has close relation with some elements including soil parent matter, aridity climate, irrigation, fertilization and cultivates measurement. Based on soil sampling and test in laboratory, the temporal and spatial difference is found in soil salt. The feature also reflects the state of water and hot condition. Based on the sampling and testing, terrain characteristics and climate condition have close relation with the salt accumulation in the irrigation area. The dominated functionary positive ion is Na⁺ + K⁺ for soil salt content. Mg²⁺ and Ca²⁺ are in the next. Meanwhile, The dominated negative ion is the SO₄^2- and Cl^-, HCO₃^- and CO₃^2- have no obviously effect for the soil salt content.To release salt accumulation, ensure the carbon cycle and maintain soil productivity, which is the important strategy for response to global change and improving the agricultural product condition.
