      abstract     = {In the humid subtropics, conversion of cropland to forest
                      has been recognized to influence carbon cycling (e.g., soil
                      CO2 emissions) and the associated ecosystem carbon balance.
                      A three-year field study was conducted in situ to
                      quantitatively evaluate effects of land use change on carbon
                      budget in a cropland (under winter wheat-summer maize
                      rotation) comparison with the adjacent forest ecosystem.
                      During the three-year experimental period, on average, soil
                      heterotrophic respirations were 35.19 mg C·m− 2·h− 1
                      for the cropland and 40.02 mg C·m− 2·h− 1 for the
                      adjacent forest ecosystem. The quantified net primary
                      production (NPP) were 8724.78 kg C·ha− 1·year− 1 for
                      the cropland (3218.14 kg C·ha− 1 for winter wheat season
                      and 5506.64 kg C·ha− 1 for summer maize season) and
                      6478.99 kg C·ha− 1·year− 1 for the adjacent forest
                      ecosystem. Thus, the average positive net ecosystem
                      production (NEP) of 5139.33 kg C·ha− 1·year− 1 and
                      2790.43 kg C·ha− 1·year− 1 were gained in the cropland
                      and the adjacent forest ecosystem, respectively.
                      Nonetheless, if take into consideration of crop grain
                      harvest (i.e., removal), the mean NEP was only 976.69 kg
                      C·ha− 1·year− 1 for cropland which were over
                      three-fold lower than for the adjacent forest ecosystem. The
                      practice of conversion of cropland (maize-wheat rotation
                      system) to forest consequently resulted in an average annual
                      net carbon sequestration of 1813.74 kg C·ha− 1·year− 1
                      in the study. Therefore, our findings highlight that
                      practices of conversion of subtropical cropland to forest
                      commonly conducted in the last decades act as sinks of
                      atmospheric CO2 in southwest China.},
