| 摘 要： | 基于土壤质地为壤土的大田水分入渗试验，分析了有机质含量对大田土壤水分入渗能力和考斯加科夫入渗模型参数的影响。研究表明：土壤有机质对大田土壤入渗能力和入渗模型参数的影响都比较明显，土壤累积入渗量随着土壤有机质含量的增加而增大；入渗模型参数k和α值随土壤有机质含量的增加而减小。研究结果对于土壤入渗能力预测模型的建立和地面灌水技术参数的优化具有一定价值。

| Abstract: | Based on the water infiltration experiments into loams in the field, the influences of organic matter content on cumulative infiltration, infiltration parameters of Kostiakov infiltration equations, and the change of infiltration capacity of field soils were analyzed and discussed in this paper. The results indicated that infiltration capacity increased while the organic matter in soils increased, and infiltration parameters k and a of soils decreased while the organic matter increased. The result is of practical meaning in developing prediction model for soils infiltration and instructing the field irrigation. |
