[Estimation of carbon emission from forest fires in Zhejiang Province of China in 1991-2006].
Forest fire is an important disturbance factor of natural ecosystem, which can release great amount of greenhouse gases. With the persistent global warming, forest fire tends to happen more frequently. Based on the statistical data of forest fires and the biomass data of dominant forest types in Zhejiang Province in 1991-2006, the annual greenhouse gases emission from forest fires in the Province was estimated by using emission factors and emission ratio. The results showed that the annual emissions of CO2, CO, CH4, and non-methane hydrocarbon (NMHC) from forest fires were 127930, 7672.8, 3098.7, and 1475.5 t, and the amounts of annually consumed biomass and carbon were 86148.1 and 38776.7 t, respectively, suggesting that forest fire had definite effects on the regional carbon budget.
