Structural characteristics of the moss (bryophyte) layer and its underlying soil structure and water retention characteristics

The influence of the moss layer on soil structure and water retention is not well understood. Therefore, this study aims to investigate changes in under reveal influencing factors these changes. 3D networks macropores were quantified using CT scanning image analysis techniques, characteristics explored through curves (SWRCs) VG model. length densities thin thick layers approximately 2.7 1.6 times higher than that no cover. greater those cover, with highest plant-available capacity layer. maximum water-holding was significantly positively correlated field negatively equivalent diameter macropores, while storage effective content soil. (FC) permanent wilting point (PWP) organic matter. effect may be mainly realized by pore distribution matter accumulation. had a positive ecohydrological even conservation forest soils.
