以河南省封丘县为研究区域,应用7种土壤传递函数(Campbell、Cosby、Brakensiek、wosten1997/1999、Saxton和Li的方法)分别对该地区不同深度土壤的饱和导水率值进行了模拟预测。通过与野外采样数据的统计分析比较,获得了适用于该地区各层次土壤饱和导水率的传递函数方程,分别选用Wosten1999和Li的方法建立了分层土壤饱和导水率分布图,为该地区的土壤水分运动模拟提供了基本土壤水文资料。
In this study, saturated soil hydraulic conduetivities of different depth of Fengqiu county were estimated by 7 pedo-transfer functions (Campbell, Cosby, Brakensiek, Wosten1997/1999, Saxton and Li methods). By comparing to measured data, the most suitable pedo-transfer functions for different soil depths (Li, Wosten1999 and Li methods) were selected to draw saturated soil hydraulic conductivity maps of Fengqiu county, and they could provide basic soil hydrological parameters for modeling soil water movements in the region.
