Wildfires are one of the main disturbance factors in forest ecosystems. Frequently occurred fires not only damage the forest ecosystems, but also emitting large amount of green house gases to the atmosphere. There have been a lot of research on the emission of green house gases of forest fires in the world, and Chinese scholars also have done a lot of research on this subject. The main shortcoming of former research on estimating green house emission from fire is mainly based on average biomass of forest ecosystems, but not based on actual biomass consumed by each fire events. Further more, there are not enough studies on the variation of green house gases emission among different forest types. What new in this research is that we used actually biomass consumed by each forest fire events to estimate green house emission for all major forest types in Jilin Province. The carbon emission from forest fires of main forest types in Jilin Province is estimated based on historical fire records during 1969-2004. These types, which are Betula alba forest, mixed broad-leaved forest, coniferous broad-leaved forest, larch forest, mongolian oak forest, Populus forest and Korean Pine forest, accounted for 997 total emission of that time, and each emitted 6593.75-8791.66, 5650.28-7533.71, 3906.57-5208.76, 211075-2814.33, 1613.71-2151.61, 295.49-393.98 and 234.37-312.50 t of carbon each year, respectively. This carbon emission is further assigned to CO2, CO and CH4 based on release ratio method. These types, which are Betula alba forest, mixed broad-leaved forest, coniferous broad-leaved forest, larch forest, mongolian oak forest, Populus forest and Korean Pine forest, emitted 21759.36-29012.48, 18645.93-24861.24, 12891.69-17188.92, 6965.46-9287.29, 5325.25-7100.33, 975.11-1300.14 and 773.43-1031.24 t of CO2 each year, respectively. Each emitted 1583.09-2110.78, 1356.57-1808.76, 937.93-1250.57, 506.77-675.69, 387.43-516.58, 70.94-94.59 and 56.27-75.03 t of CO each year, respectively. Each emitted 534.71-712.94, 458.20-610.93, 316.80-42239, 171.17-228.22, 130.86-174.48, 23.96-31.95 and 19.01-25.34 t of CH4 each year, respectively. Time serial analysis shows that 3 main types, Betula alba forest, coniferous broad-leaved forest, and Korean Pine forest stopped being main carbon sources in 1980, 1984, and 1983 respectively. Currently, main carbon emission forest types are mixed broad-leaved forest, larch forest, mongolian oak forest and populus forest. The mongolian oak forest is especially high carbon source with annual emission of 237.12-316.16 t.
