Abstract:

In recent years锛� environmental pollution problems caused by straw burning and industrial emissions have become more serious. The use of satellite thermal abnormal products to analyze the temporal and spatial distribution of thermal abnormalities plays an important role in environmental monitoring. Based on MODIS standard products from 2001 to 2018锛� the temporal and spatial distribution characteristics of thermal anomalies in China and seven major regions are studied. The results showed that锛� in terms of spatial distribution锛� thermal anomalies are mainly distributed in most areas except Northwest and East China. In terms of inter-annual trends锛� the number of thermal anomalies continued to increase from 2001 to 2014 years锛� with an average annual growth rate of 15.01%锛� 2015 years After that锛� it decreased year by year锛� with an average annual decline rate of 14.96%. On month and season scales锛� thermal anomalies occur most frequently in spring and autumn 锛坰pring锛� 551 716锛� autumn锛� 416 698锛夛紝 Spring and autumn are relatively most distributed in Northeast China 锛坰pring锛� 164 898锛� autumn锛� 186 727锛�. The highest in October 锛�118 274锛夛紱 the lowest number of hot anomalies in summer 锛�290 793锛夛紝 mostly distributed in East China 锛�120 455锛夛紝 the average monthly number in East China is the highest in June 锛�76 465锛夛紱 the number in winter is 358 483锛� South China has the most distribution 锛�108 209锛夛紝 and South China has the highest monthly average number in January 锛�37 770锛�. This research is helpful to master forest and grassland fires in typical regions of China锛� as well as changes in thermal abnormalities caused by straw burning and industrial emissions锛� and then provide technical support for regional disaster prevention and environmental monitoring.
