Eurasian boreal forest possesses rich forest resources and accounts for 25% of global forest cover. Changes in forest cover and structure caused by human-induced or natural forest disturbances, such as forest fires,have significant impact on the forest carbon cycle. The considerable progress on earth observation technology makes it entirely possible to provide dynamic monitoring of forest resources. This paper discusses the spatial and temporal changes of forest fire disturbance in European Russia. MODIS Thermal Anomalies/Fire product contains information such as fire location, credibility, fire point radiation energy and other attribute information, which can be used for the monitoring of fire frequency, level, and changes. In this study we use MODIS Thermal Anomalies/Fire daily product from 2005 to 2010, combined with RS image processing and GIS spatial analysis methods, to identify burned pixels in European Russia. Spatial and temporal distribution of forest fire has been analyzed. At last we estimate the amount of loss caused by forest fires. The result shows that forest fires are mainly distributed in central and southern regions of European Russia and the fire number is showing an upward trend, fire coverage of 2010 is 1.5 times greater than that of 2005. The fire data reveals apparent changes within a year, and the fire season is generally from April to October. Large fire events occurred in 2010 can be well reflected in the results of this study.
