Carbon exchange from four agro-ecosystems on the Loess Plateau,China

摘要：

Introduction Soil CO2 flux to the atmosphere is a significant component of the global C cycle,approximately 10％ of the atmospheric CO2 pool (Jenkinson et al.,1991) and the second largest flux between terrestrial ecosystems and the atmosphere ( Raich and Tufekcioglu,2000).The Loess Plateau has one of the more developed agricultural systems in the world and has the longest cropping history in China.The objective of this study was to estimate the amount of carbon sequestration and soil emissions from different agro-ecosystems in the representative areas of the Loess Plateau.
