Dynamics of carbon and nitrogen storage in two typical plantation ecosystems of different stand ages on the Loess Plateau of China.

ABSTRACT: In China's Loess Plateau, afforestation and reforestation are considered the foremost practices for sequestering carbon and conserving soil and water. In order to evaluate the carbon storage changes of tree, soil, and litter, and the soil total nitrogen (STN) in two typical artificial forests in the region, we conducted plot surveys for different ages of both artificial forest types. Soil samples were collected at different depths from 0-100 cm. The results indicated that forest ecosystem carbon storage increased with tree development. The rates of mean annual carbon sequestration of Pinus tabulaeformis and Robinia pseudoacacia plantation ecosystems were 3.31 and 3.53 Mg ha^-1 year^-1, respectively. The rate of mean annual carbon sequestration of R. pse
