[Carbon losses from forest fire in Jiangxi Province, China in 1950-2008].
The annual occurrence of forest fire in Jiangxi Province of China in 1950-2008 was averaged 762 times and covering 1.578 x 10(4) hm2. Based on the forest fire statistic data, meteorological data, forest inventory data, and other parameters, this paper analyzed the characters of forest fire in the province, and estimated its carbon release and transfer. In the province, the total forest biomass loss from forest fire in 1950-2008 was about 61. 155 Tg, and the biomass carbon loss was about 30.993 Tg C, accounting for 15.92% of the vegetation carbon pool in the whole province. Before the 1970s, the biomass carbon loss occupied 74.3% of the total loss in 1950-2008, but after the 1990s, this loss decreased rapidly, with an annual average carbon loss less than 0.097 Tg C. The released CO2, CH4, and CO from the forest fire were about 5.408 Tg, 0.047 Tg, and 0.486 Tg, respectively, and led to 22.436 Tg of biomass carbon transferred into soil carbon. The snow and ice disaster in the beginning of 2008 resulted in high frequency forest fire, and led to a 0.463 Tg biomass carbon loss, which was 2. 56 times of the average value (0.181 Tg) in 2003-2007.
