Influence of plantation of a shelter-belt on component of organic carbon in the Taklimakan desert over last decade

Abstract

The soils were collected from the Taklimakan Desert Highway shelter-belt with different planting years in Xinjiang, northwest of China. The soil organic carbon stork (SOCstork) in each layers. By chemical and physical pretreatment, we measured four carbon passive organic carbons, i.e., microaggregates organic carbon(OCMIA), humus organic carbon (OCHS), carbon resistance to oxidation (OCNaClO) and acid hydrolysis (OCHCl). The results showed that the OC and SOCstork was decreased with soil depth mainly in 0-50 cm. The artificial vegetation have more influence on TOC, OCMIA and OCHS than OCNaClO and OCHCl. The Tamarix chinensis shelter-belt is the most helpful for carbon sequestration in sandy soil and stabilization in surface layer than Calligonum mongolicunl and Haloxylon ammodendron.
