graph maps ( at 1:50000 scale ) and supplement cert-

maps ( at 1:200000 scale).
2 ), The procedure of the interpretation and maping
as follow:
The preparation ( including the data and materials
were collected and basic maps as well as transparence
topographic maps were made ).
The interpretation ( including interpretation mark
were established by going to the field and in the lab.
and defined the standard of clssification and deline-

The going to the field for interpretation check.
The making final maps and caculating the areas.
3 ), The accuracy of identify were about 94« 1 per-
sent that was in comparison with airphotos.
4 ), This method of Song-nen plain natural resour
ces and land use invintory was correct, rapid, and
