3 CONCLUSIONS
According to the above-mentioned principles
and.foundations for establishing the expla
natory symbols, we must first set up the vi
sual explanatory symbols and the interpreta
tion indexing catalogue of the various re
sources in the work area, And then, use the
various optically processed satellite and
aerial photos to visually interpret and ex
plan, to classify various resources, and to
draw various specialized diagrams with a
scale of 1:50,000.It has been proven by field
experiments, that the rate of accuracy can
amount to 92.3%.
By this method, we have investigated clea
rly the area of forest distribution, the
form of forrests and their storage amount,
and the area, grade, and yield of reed re
sources, in our working area. At the same
time, we also clorifid the type and distri
bution area of grasslands, vegetation cover,
and the soil resources in the area. This has
provided a scientific foundation for produc
tion planning and distribution.
