中文摘要: 生物质燃烧是重要的气候强迫因子,也是影响空气质量的重要污染源。黑龙江作为农林业大省,森林、草地、农业资源丰富,研究和分析黑龙江生物质燃烧情况,能够为秸秆资源综合利用、森林草原防火、环境质量改善等提供依据。本研究基于MODIS卫星数据、土地利用数据及高程数据,对黑龙江2010-2017年生物质燃烧火点时空分布特征进行了分析,包括秸秆焚烧火点、林火、草地野火。结果表明,黑龙江省火点主要集中在松嫩平原、三江平原以及小兴安岭中北部;黑河市火点占总火点的30%,齐齐哈尔次之,占16%;秸秆焚烧火点占总火点的68%,林火占32%。年内火点在春、秋两季最为明显,呈双峰分布,春秋季火点数占比分别为51%、45%。2010年以来林地与草地火点数量波动较小;秸秆焚烧火点数量自2014年起显著增加(P<0.05),2016年禁烧政策的开展下火点数量得到控制,秋季火点减少,但春季依旧呈现增加趋势。
英文摘要: Biomass burning is an important climate forcing factor and pollution source that affects air quality.As a big province of agroforestry,crop straw and rich forest resources,research and analysis of biomass combustion conditions in Heilongjiang Province can benefit for the comprehensive utilization of straw resources,forest fire prevention,and environmental quality improvement.Temporal and spatial distribution characteristics of biomass burning spots are analyzed based on the MODIS sensor data,land use data and altitude data of the Heilongjiang Province in 2010-2017.The results showed that the fires in Heilongjiang Province are mainly concentrated in Songnen Plain,Sanjiang Plain and the north-central part of Xiaoxingan Mountain.Hehe City fire accounted for 30%of the total fire,followed by Qiqihar,accounting for 16%.Straw burning fires accounted for 68%of the total fires,forest fires 32%.The annual fire point was the most obvious in spring and autumn, showing a double peak distribution.The ratio of fire points in spring and autumn was 51%and 45%respectively. Since 2010,the number of forest and grassland fires has fluctuated less.The number of straw burning fires has increased significantly since 2014.In 2016,the number of non-burning fires under the implementation of the no-burning policy has been controlled,and the number of burning fires in autumn decreased,but it still shows an increasing tendency in spring.
