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

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
