吉林省森林火灾释放碳量的时间变化规律
Time Variation of Carbon Emission from Forest Fires in Jilin Province
【摘要】 根据吉林省1969—2004年的森林火灾统计数据,计算出吉林省森林火灾年均释放碳22004.38~29339.17t,约占全国年均森林火灾排放碳的1.05%。用排放比法得出吉林省年平均森林火灾释放的CO2、CO、CH4量分别为72614.45~96819.27、5283.01~7044.02和1784.40~2379.20t。吉林省森林火灾碳和含碳气体释放最多的月份是9月,占总释放量的60.6%,其次为10、5和4月,分别占总释放量的16.1%、11.4%和9.8%。吉林省森林火灾碳和含碳气体释放最多的时间段是13:00—13:59,占总释放量的31.4%,其次是14:00—14:59、15:00—15:59和11:00—11:59,分别占总释放量的18.7%、16.4%和16.0%。
【Abstract】 The mean annual carbon emissions from forest fires in Jilin Province is estimated to range between 22 004.38 t and29 339.17 t,accounting for 1.05 percent of the total national emissions,based on the forest fire data from 1969 to 2004.The annual emissions of CO2,CO and CH4 from forest fires every year in Jilin Province range from 72 614.45 t to 96 819.27 t,5 283.01 t to 7 044.02 t and 1 784.40 t to 2 379.20 t,respectively.Carbon and carbonaceous gas emissions from forest fires are the most in September,making up about 60.6 percent of the total,and then followed by October(16.1 percent),May(11.4 percent)and April(9.8 percent).Carbon and carbonaceous gas emissions from forest fires are the most at 13:00—13:59,accounting for about 31.4 percent of the total,and then followed by 14:00—14:59(18.7 percent),15:00—15:59(16.4 percent)and 11:00—11:59(16.0 percent).
