2017年春季辽宁省秸秆焚烧火点遥感监测分析

简述了常用于监测秸秆焚烧火点的遥感数据源和监测原理,采用MODIS和VIIRS 2种数据对2017年辽宁省春季秸秆焚烧火点进行监测分析。结果表明,沈阳监测到的火点数量最多,占全省总数的28.0%,本溪最少;采用VIIRS数据监测到的火点数明显多于MODIS数据的监测结果。

On the basis of the review about the remote sensing data source and monitoring principle of crop residue burning site, the fire sites of burning crop residue of Liaoning Province in spring 2017 were monitored and analyzed by using MODIS data and VIIRS data. The results showed that the number of fire sites were monitored in Shenyang City is the largest, accounting for 28.0% of the total number of the province, and the minimum was monitored in Benxi City.
