Abstract: Taking the tier soil and loessal soil in 0-30cm and 30-100cm layers as the experimental soil, this paper studied the influence of EN-1 soil stabilizer on soil infiltration capacity and on the soil structure, soil moisture-holding capacity and soil acidity. Using the indicators for showing the soil structure, soil moisture-holding capacity and soil acidity, and using the stepwise regression analysis method, this pa per studied the evaluating indicators for soil infiltration capacity after the application of stabilizer to soil and established its linear simulation equation. The results indicate that the influence degree of stabilizer on soil physical and chemical characters is related with the stabilizer content, soil type and soil layers. In the evaluating model of soil infiltration capacity, the selection of other indicators changed with the soil type and layers except the amount of soil water-stable aggregates and retained water content.

Key words: EN-1soil stabilizer; soil infiltration capacity; stepwise regression analysis; model
