Abstract:

In this study锛� different types of NPP VIIRS 375 m active fire product 锛圓CF锛孨PP-VIIRS active fire/hotspot data锛� in Handan were analysed based on heavy industry heat sources detection model base on long-term data. 锛�1锛� 81 heavy industry heat sources worked between 2012 and 2020 were detected based on 89 249 ACF data. They were mainly distributed in the hilly area 锛坱he west of Beijing Guangzhou line and G4 Expressway锛夛紝 especially in Shexian锛� Wu'An and Fengfeng mining areas. It was consistent with the distribution of mineral resources in Handan city. And锛� compared the num of working heavy industrial heat sources between 2020 and 2013锛� 32 锛�42.67%锛� industrial heat sources were shut down锛� 19 锛�25.33%锛� industrial heat sources which thermal abnormal points were significantly reduced锛� also 5 new enterprises appeared. And heavy industrial heat sources detected were maily belong to iron and steel and foundry锛� coal chemical and coking锛� cement plants锛� accounting for 53.24%锛� 28.16% and 0.08% respectively. 锛�2锛� Betwwen 2012 and 2020锛� the average annual proportion of thermal anomaly points from industrial heat sources was 91.61%锛� especially more than 94.34% in 2016. There was 42.73% of ACF data on the cultivated land surface coverage belonging to industrial thermal anomaly points锛� 5.5% data on the artificial surface coverage belonging to non industrial thermal anomaly points. And锛� the most of industrial heat anomaly points in Handan were on the artificial land 锛坅ccounting for 89.87%锛夛紝 while the most of non industrial heat anomaly points were on the cultivated land 锛坅ccounting for75.93%锛�.There was obvious "double peak" phenomenon 锛坵ith a larger peak point in June / October锛� for the monthly statistical chart锛� which has disappeared since 2018.

Key words: Heavy Industry Heat Source, Active Fire data, Long-term, Handan
