The flow of the entire renewal is completed through the organic 
synthesis of field operation and office operation, and the office 
work full excavates each kind of data information existing to 
confirm the forest change information; then through field 
operation GPS investigation to see office work correct or not; 
finally carries on the compilation of the forest graphic or the 
database renewal under the unified GIS software platform, and 
produces the statistics report form and the graphic of the forest 
resources. The renewal flow is a quite complex project, which 
not only needs very strong office work handling ability, but 
also needs the good ability of GPS field actual operation and 
investigation. Moreover the two must union closely and 
complement each other. 
3. THE DYNAMIC MONITORING OF FOREST 
RESOURCES ON THE INTEGRATION OF 3S 
Formidable forest resources ground datum can be gained by the 
using of the GPS fast accurate localization function and the 
magnanimous data of RS is processed by the GIS software, 
which provides the fast accurate useful data to the user. By the 
contrast of the historical database and the renewal database 
information we may discover the change situation of the forest 
resources very quickly. The Dynamic Monitoring System of 
Forest Resources on the Integration of 3S is shown in Figure 3 
positioning and original data 
Figure 3. The Dynamic Monitoring System of Forest Resources on the Integration of 3S 
It is easy for the “3S” technology to overcome the the flaw of 
the traditional monitor system. We can do: (1) dynamic 
monitoring of spatial distribution information forest resources; 
(2) not only carry on the macroscopic monitoring of forest 
resources to national and the wide range but also carry on the 
monitoring of forest resources change to the partial microscopic 
region; (3) in monitor content, not only carry on the monitoring 
of the forest resources quantity, also strengthen to the 
ecological environment information dynamic monitor; (4) in 
data renewal aspect, use “3S” technology real-time function, to 
complete the data renewal of the monitoring system. 
Using “3S” the technology to monitor the forest resources, will 
be able effectively serve for the national economy development 
and the ecological environment construction.
