To examine the pore-size distribution (PSD) evolution of intact, compacted, and saturated loess during deformation associated with consolidation or shearing, nominally identical specimens were consolidated to different confining stresses sheared sequential axial strains under same stress, PSD each deformed specimen was characterized using Mercury intrusion porosimetry (MIP) technique. The resul...
Native tree species are frequently unable to effectively grow in non-native cultivation scenarios. In the Loess Plateau, China, it is difficult find native oak (Quercus liaotungensis) seedlings black locust forests. Black an arbuscular mycorrhizal (AM) tree, but ectomycorrhizal (ECM) tree. Plants highly depend on their symbiotic fungi take up water, nitrogen (N) and other nutrients. We hypothes...
Soil erosion is a problem that affects the landscape at different scales and represents serious challenge for land management soil conservation in both natural forests meadows. The aim of this study was to determine how parent material use affect physical chemical properties area Fruska Gora Mountain. soils were separated into five bedrock types: serpentinite, marl, trachyte, shale, loess two f...
Tree-ring samples from Chinese Pine (Pinus tabulaeformis Carr.) collected at Mt. Shimen on the western Loess Plateau, China, were used to reconstruct the mean May-July temperature during AD 1630-2011. The regression model explained 48% of the adjusted variance in the instrumentally observed mean May-July temperature. The reconstruction revealed significant temperature variations at interannual ...
The Loess Plateau is well known for its deep loess deposits and serious soil erosion. This paper analyses the characteristic of soil erosion on the Plateau and reviews the small watershed management and ecosystem rehabilitation practice and development in the future. In the last 30 years, the government has paid great attention on the integrated small watershed management and restoration of the...
Microplastics are abundant in agricultural soils and have significant impacts on rainfall infiltration soil water-retaining capacity. To explore the effect of microplastics permeability by simulating irrigation process, a one-dimensional vertical column test device was used to study unsaturated characteristics loess imbued with under conditions. The following conclusions could be obtained: micr...
