摘　　要：本文以0～30cm和30～100cm土层的填土和黄绵土为供试土壤,研究了EN-1固化剂的施用对土壤入渗能力、土壤结构、土壤持水能力和土壤酸度的影响.以表征土壤结构、土壤持水能力和土壤酸度的指标作为土壤入渗能力评价指标,利用逐步回归分析法,建立了经固化剂处理后的土壤入渗能力评价模型.研究结果表明,EN-1固化剂对土壤物理和化学性质的影响程度与固化剂掺量、土壤类型和土壤的取土层次有关.在评价土壤入渗能力的模型中,除大于0.25mm的毛管饱和水稳性团聚体含量和滞留含水量是共有指标外,其它指标的选取随土壤类型和取土层次的不同而改变.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.
