Erosion-induced massive organic carbon burial and carbon emission in the Yellow River basin, China
Soil erosion and terrestrial deposition of soil organic carbon (SOC) can potentially play a significant role in global carbon cycling. Assessing the redistribution of SOC during erosion and subsequent transport and burial is of critical importance. Using hydrological records of soil erosion and sediment load, and compiled organic carbon (OC) data, estimates of the eroded soils and OC induced by...
متن کاملDynamics of soil organic and inorganic carbon in the cropland of upper Yellow River Delta, China
Soil inorganic carbon (SIC) and organic carbon (SOC) are important carbon reservoirs in terrestrial ecosystems. However, little attention was paid to SIC dynamics in cropland. We conducted a survey in the upper Yellow River Delta of North China Plain. We collected 155 soil samples from 31 profiles, and measured SOC, SIC and soluble Ca2+ and Mg2+ contents. Our results showed that mean SOC conten...
متن کاملSoil organic carbon of degraded wetlands treated with freshwater in the Yellow River Delta, China.
Supplying freshwater is one of the important methods to help restore degraded wetlands. Changes in soil properties and plant community biomass were evaluated by comparing sites with freshwater treatment versus reference sites following freshwater addition to wetlands of the Yellow River Delta for 7 years. The results indicated that soil organic carbon (SOC) was significantly increased in all we...

15 صفحه اولManaging Soil Erosion on the Loess Plateau of China to Control Sediment Transport in the Yellow River-A Geomorphic Perspective
A key part of the strategy to manage the problems of flooding and sedimentation of the lower Yellow River in China is the control of soil erosion on the loess plateau. Land use practices are assumed to be the root cause of the high sediment yield and therefore able to be controlled. An analysis of the geomorphology of the loess plateau region shows that there are natural causes of high sediment...
