Academy of Sichuan, Chengdu 610081, China) Abstract:
Multiple ecological benefits have been the society's focus during
the process of the forest recovery since the natural forest's
resources protection engineering was carried out. A study on the
dynamic monitoring which based on the benefits monitoring
information system included the resources, environments and
ecological benefits in the natural forest protection engineering
regions. The system was founded by spot monitoring, field
investigation and resource statistic according to the zoning by the
natural geographical characteristic of the forest vegetation. The
results from 1999 to 2001 showed below: The forest area was 1751.964×104hm2,
the standing timber volume was 12.11×108m3
in 2001, which increased 2393.57×104m3
during the three years. The total forest biomass was 10.04×108t,
which increased 6374.2×104t
and the carbon sink of forest was 3187.1×104t.
The total litter storage quantity was 1887.94×104t
as well the returning quantity was 3241.4×104t.
The returning quantity of nitrogen, phosphorus and kalium with the
litter was 52.25×104t. The entrapment
quantity of soil and sand was 2.06×108t.
The ability of the total water storage was 200.74×108t.
It also studied and evaluated the costs of per year ecological
benefits and ecological service. Keywords:
natural forest resource; benefits; monitoring and evaluation
