Spatial Analysis on Surface Deformation by Soil Erosion in the Chinese Loess Plateau Using Insar Techniques
Monitoring the surface deformation over the loess hills could help us understand the dynamics of soil erosion, the extent of anthropogenic impacts, and the mitigation methods for the potential damage to local ecosystems, agricultural production, socioeconomic infrastructure, water quality, and air quality in the Loess Plateau and the surrounding areas. The objectives of this study were to compr...
متن کاملSpatial Variability of Soil Erosion and Soil Quality on Hillslopes in the Chinese Loess Plateau
Soil erosion rates and soil quality indicators were measured along two hillslope transects in the Loess Plateau near Yan'an, China. The objectives were to: (a) quantify spatial patterns and controlling processes of soil redistribution due to water and tillage erosion, and (b) correlate soil quality parameters with soil redistribution along the hillslope transects for different land use manageme...
متن کاملRegional Evaluation of Soil Erosion by Water: A Case Study in the Loess Plateau of China
Astract: This paper shows how recent situation of soil erosion evaluation and prediction on a regional scale based on the techniques of spatial information. The study, which was carried out in central China, identified sediment discharge, precipitation, soil composition, gully density and land use as erosion factors at the regional level. It showed that soil erosion can be assessed and predicte...
متن کاملSoil erosion and sediment transport in the gullied Loess Plateau: Scale effects and their mechanisms
Scale effects exist in the whole process of rainfall―runoff―soil erosion―sediment transport in river basins. The differences of hydrographs and sediment graphs in different positions in a river basin are treated as basic scale effects, which are more complex in the gullied Loess Plateau, a region notorious for high intensity soil erosion and hyper-concentrated sediment-laden flow. The up-scalin...
متن کاملThe Relationships between Soil Erosion and Human Activities on the Loess Plateau
The Loess Plateau lies in the North of China and is one of the most serious regions of soil erosion in the world. Severe loss of soil and water not only has its devastating effect on farming, forestry, stock-breeding and ecological environment of the area concerned, but also is the root of poverty for local people. The Loess Plateau has a long cultivation history, hence population growth, veget...
