文摘

Fine root biomass and production decreased in shrubland converted from steppe. Soil organic carbon (SOC) stocks also declined in converted shrubland. Herbaceous fine roots in shrubland had highest turnover and decomposition rates. Fine root dynamics exert strong influence on SOC stocks and fractions. Shrubland conversion is not appropriate for land degradation control.
