This research is based on the standard false colour composite images of French SPOT satellite obtained on 30th

May

1987 as main infcrmation resource to study forest fire damages of the forest land in Amuer Forest Bureau of Great Xingan Mountains.The article is emphasis on principles

methods and errors of area measurement. The comparison is made between the results of district forest surrey （a kind of field surrey） and the method of calculated timber stock volume damage using moderate ground sample plots enumeration and visual measurement assisted by an angle gauge as well as with statistical sampling techniques; particularly

the comparison of consistency among the image interpretation of forest fire damage classes

the ground landscape and the percentages of burn-out timber stock （quantitative description of forest fire damages）.The results show that the application of SPOT satellite data to estimate forest fire damage using the above introduced research method can quicply and economically obtain the necessary results and meet the requested precision.
