| Research Abstract |
Carbon sequestration by saline or alkaline soils through inorganic way and its dynamics in arid ecosystems have been linked with the"missing carbon"mystery which plays a critical role in global scale carbon cycle in recent. However, evaluation of the approach remains a dilemma due to scarcity of available data. This study tries to understand the dynamics of inorganic carbon stocks and abiotic CO_2 exchanges in most barren ecosystems in the world, which may help to solve'missing carbon'. In detail, soil carbon stocks are estimated by lab analysis, soil respiration is quantified by soil respiration chambers and is estimated through eddy covariance in large scale. Furthermore, remote sensing techniques are extensively involved to estimate carbon sequestration in arid area.
