摘要: Field observations and literature reveal that land use soil characteristics play an important role in the devel- opment of piping. In this study, hypothesis is tested discontinuities profile favour piping erosion loess-derived soils a temperate humid climate. Abiotic (clay content, bulk density, Ksat, penetration resis- tance) biological activity were measured for each horizon until depth at least 40 cm below pipes (ca. 1.30 m) 12 representative profiles with different (pasture without collapsed pipes, arable forest). No clear abiotic observed depths where subsurface oc- curred, but pastures had significantly more earthworm channels mole burrows larger than piping, or forest.
