| 摘 要： | 在野外原位入渗试验的基础上,建立了简化Philip入渗模型及其土壤转换函数,借助ARCVIEW软件生成了石羊河流域平原区土壤入渗特性参数的空间分布图,并分析了入渗特性的空间变异特征。研究表明,简化Philip入渗模型是点面转化中比较理想的模型,模型参数α的土壤转换函数可以简便地估算土壤入渗特性,两者的结合是研究大尺度土壤入渗空间变异的一种有效方法。

| Abstract: | The spatial variability of the regional soil water infiltration is one of key issues now, yet there is no better ways to solve it.Based on the experiment data, the simplified Philip model of soil water infiltration and the pedo-transfer functions (PTFs) are established.By using ARCVIEW software, the distribution of infiltration parameters of the plain region of Shiyang river basin are drawed by these two models and the spatial characteristics are analyzed.The results indicate that the simplified Philip model is suitable for the study of transfer from points to region, the PTFs of the infiltration coefficient α can simply calculate the infiltration parameters, the combination of the simplified Philip model and the PTFs is the simple and beneficial method for the research of the spatial variability of the soil water infiltration characteristics of the large-scale region. |
