Natural Vegetation Restoration Is More Beneficial to Soil Surface Carbon Sequestration on Loess Plateau

摘要

The Loess Plateau of China is a unique geographical unit characterized by extensive loess distribution,serious soil erosion,low vegetation coverage and high soil carbonate content.Since the 1950s,the Chinese government has made great efforts to control soil erosion and restore vegetation,including large-scale tree plantation in the 1970s,integrated soil erosion control in the 1980s and 1990s,and the'Grain for Green Project'in the 2000s.Currently,the
