Soil Erosion and Controls in the Slope-Gully System of the Loess Plateau of China: A Review

The Loess Plateau has long been suffering from serious soil erosion of which the slope-gully system is now dominant. characterized with distinctive distribution zones consisting inner and inter gully areas wherein patterns spatially vary, acting as both sediment source dominant water transport mechanism. In this paper, a substantial body research reviewed concentrating on processes control practices in system. area identified main while runoff inter-gully upland found to significantly affect down slope processes. Correspondingly, protective vegetation pattern coverage should be strategically designed for different an emphasis critical cover reduce yield whole Check-dam could change base level length side, will further decrease possibility magnitude gravity erosion. We concluded that understanding implementing are importance require more efforts emphasize: 1) influence at downslope; 2) relationship between hydraulic characteristics overland flow process scale; 3) physical mechanisms process.
