利用室内定水头入渗法,观测三峡不同森林地段烘干土的入渗性能,比较大孔隙域与基质域烘干土入渗的差异,探究影响烘干土入渗性能的原因,评价常用入渗模型对不同属性烘干土壤入渗过程的适宜性。结果表明:三峡库区各森林地段基质域A层土壤的入渗能力强于B（或C）层土壤,B（或C）层土的40 min累积入渗量只占到A层土的29.79%45.07%;不同林型覆盖下基质域烘干土壤入渗能力相比较,温性落叶阔叶林山地棕壤>常绿落叶阔叶混交林山地黄棕壤>暖性针叶林山地黄壤>常绿阔叶林山地棕红壤,温性落叶阔叶林山地棕壤40 min的累积入渗量是常绿阔叶林山地棕红壤的32.0848.53倍。大孔隙域烘干土的入渗速率亦符合先下降...

This study used the constant waterhead infiltration method to compare the infiltration characteristics of homogeneous oven-dried soils in different mountain forest districts of Three Gorges Reservoir area. Our objectives were to explore the infiltration differences of oven-dried soils between macroporous and in homogeneous domain and to evaluate the suitability of infiltration models during the infiltration process of different oven-dried soils. The results showed that the infiltration capacity of topsoil was better than that of subsurface soil...
