| Zusammenfassung |
| Recent studies based on remote sensing and carbon process models have
revealed that terrestrial net primary production (NPP) in the middle and
high latitudes of the Northern Hemisphere has increased significantly; this
is crucial for explaining the increased terrestrial carbon sink in the past
several decades. Regional NPP estimation based on significant field data,
however, has been rare. In this study, we estimated the long-term changes in
aboveground NPP (ANPP) for Japan's forests from 1980 to 2005 using forest
inventory data, direct field measurements, and an allometric method. The
overall ANPP for all forest types averaged 10.5 Mg ha−1 yr−1, with
a range of 9.6 to 11.5 Mg ha−1 yr−1, and ANPP for the whole
country totaled 249.1 Tg yr−1 (range: 230.0 to 271.4 Tg yr−1)
during the study period. Over the 25 years, the net effect of increased ANPP
in needle-leaf forests and decreased ANPP in broadleaf forests has led to an
increase of 1.9 Mg ha−1 yr−1 (i.e., 0.79 % yr−1). This
increase may be mainly due to the establishment of plantations and the rapid
early growth of these planted forests. |
