erosion.Soil erosion in northern Shaanxi region has been greatly affected by human activities. On the one hand, newly occurred soil and water loss has been observed due to accelerated soil erosion caused by irrational human economic activities such as excessive reclamation, mining, etc.. ...
The biogeochemical footprint of agricultural soil erosion We discuss the major processes through which erosion affects these global cycles and pay particular attention to the knowledge gaps that prevent us from accurately assessing the impact of soil erosion on global biogeochemical cycling at ... G ...
The Impact of Agricultural Soil Erosion on the Global Carbon Cycle. Agricultural soil erosion is thought to perturb the global carbon cycle, but estimates of its effect range from a source of 1 petagram per year-1 to a sink... - 《Science》 被引量: 724发表: 2007年 Agricultural activities...

on soil erosion risk assessment,an improved method of soil erosion risk assessment was adopted in this paper.Firstly,distribution of soil erosion degree by various impact factors including altitude,gradient,land use type and soil types were calculated by GIS and statistic analysis.Secondly,integrative ...
Soil erosion processes in vineyards, beyond surface runoff and sediment transport, have a strong effect on soil organic carbon (SOC) loss and redistribution along the slope. Variation in SOC across the landscape can determine differences in soil fertility and vine vigor. The goal of this research...
Human activity and related land use change are the primary cause of accelerated soil erosion, which has substantial implications for nutrient and carbon cycling, land productivity and in turn, worldwide socio-economic conditions. Here we present an unprecedentedly high resolution (250×250m) global ...
Therefore, along with the procedures to terminate contamination, an investigation with family members and the people present at the time of contamination, and information on patient care should exist. These individual will be questioned, about the way in which the patient was exposed to the ...

The potential for global climate changes to increase the risk of soil erosion is clear, but the actual damage is not. The objectives of this study were to evaluate the potential impacts of climate change on soil erosion, surface runoff, and wheat productivity in central Oklahoma. Monthly project...
