摘要:

根据黑龙江省1980—1999年的森林火灾统计数据和对黑龙江省各森林类型地上生物量的估算,计算出黑龙江省森林年平均森林火灾损失地上生物量391758.65~522344.95t,占全国的6.4%~8.4%。年均释放碳176291.39~235055.23t,约占全国年均森林火灾排放碳的8%。用排放比法得出黑龙江省年平均森林火灾释放的CO2、CO、CH4、NMHC量分别为581761.6~775682·25t、34892.275~46523.04t、14091.11~18788.15t和6500~9000t。

Abstract:

Forest fire is an important natural factor influencing the balance of atmospheric carbon in global change. In recent years, due to the human activities and some terrific climate events associated with global change, forest fires are aggravated day by day and effects global forest ecosystem. The influence of global climatic change from greenhouse gas included carbon from forest fires cause more attention. Based on the data of forest fire accounting from 1980 to 1999 and ground biomass estimation for some forest types in Heilongjiang Province, the amount of mean annual consumed biomass of forest was estimated to be {391 758.65~}522 344.95 t,about 6.4%~8.4% of total national consummation from forest fires, and the amount of carbon released to be 176 291.39~235 055.23 t, about 8% of total national emissions from forest fires. CO2、CO、CH4 and NMHC emission from forest fires every year in Heilongjiang Province were 581 761.6~775 682.25 t、34 892.275~46 523.04 t、(14 091.11~)18 788.15 t和6 500~9 000 t.
