2019年黑龙江省秸秆焚烧时空分布研究

Study on the Temporal and Spatial Distribution of Straw Burning in Heilongjiang Province in 2019

近年来,秸秆焚烧给周围的大气环境造成了巨大的影响,是形成雾霾的重要原因之一,影响人们的日常生活.主要基于VIRR火点监测数据,对黑龙江省2019年全年火点时空分布进行分析,选取全年火点数量最多的3、4月份,对其进行时空分布研究,得出了3月份有4个城市火点数量都超过了1000个,其中最多的是黑河市;而在4月份火点数量最多的是齐齐哈尔市,火点数量也超过了1000个.通过对黑龙江省2019年火点分布研究,可以给相关部门提供有效监测火点的依据,改善大气环境质量.

In recent years,straw burning has greatly affected the atmospheric environment around us.It is one of the important reasons for smog formation and affects people's daily life.Based on VIRR fire monitoring data,in this paper the temporal and spatial distribution of fire points is analyzed in Heilongjiang Province in 2019.March and April are selected,which are the largest number of fire points in the year,and their temporal and spatial distribution are studied.It is concluded that there are four cities with more than 1000 fire points in March,the largest of which is Heihe City.In April,Qiqihar is the city with the largest number of fires,with more than 1000.Through the research on the distribution of fire spots in Heilongjiang province in 2019,the basis for relevant departments to effectively monitor fire spots is provided,and the quality of atmospheric environment is improved.
