Responses of runoff and sediment yield to rainfall regimes in a typical slope–gully system on the Loess Plateau: A 24-year field monitoring study

open access: yesGeoderma
Slope–gully system serves as a critical erosion unit on the Loess Plateau, and its slope and gully refer to summit and ridge, and steeper gully wall, respectively.

Impacts of Grass Coverage and Arrangement Patterns on Runoff and Sediment Yield in Slope-Gully System of the Loess Plateau, China

open access: yesWater, 2022
Both vegetation coverage rates and arrangement patterns have important influences on erosion. Very little previous research focuses on the impacts of spatial vegetation distribution patterns on erosion. The slope-gully system was taken as the research object, which is composed of a 5.0 m long hillslope with a slope gradient of 20° and a 3.0 m long ...

The importance of terrain factors in the spatial variability of plant cover diversity in a steppe gully

open access: yesBiosystems Diversity, 2023
Information about the slope angle and its exposure is often given when describing plant communities. However, the slope angle should be noted to affect a complex of different phenomena and processes.

Using high-resolution aerial images to study gully development at the regional scale in southern China

open access: yesInternational Soil and Water Conservation Research, 2020
There are 239,100 gullies in southern China, which cause the degradation of ecological system. However, studies on gully development at the regional scale is relatively lack. The purpose of this study is to analyze the regional gully dynamics and explore

The Progressive Failure Mechanism of the Tunnel-Slope System under Rainfall: An Experimental Investigation

open access: yesGeofluids, 2022
Tunnel excavation has always been an important reason for the stability failure of the tunnel-slope system at the portal section. In case of rainfall, it is likely to cause serious disasters such as tunnel vault collapse, water inrush from the tunnel ...

Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

open access: yesBiological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.
