Résumé partiel
Wildfires include forest fire,brush fire,and grassland fire.East Asia is rich in forest and grassland resources.Forest is the main body of terrestrial ecosystem,which is the largest,most complex,multi-species,multi-function and multi-benefit ecosystem on the land.Grassland is an important part of the terrestrial ecosystem and plays an important role in the ecosystem.As the emissary of human civilization,wildfire plays an important role in the natural ecosystem.Each occurrence of wildfires causes incalculable damage to natural resources such as forest resources,grassland resources,economic losses and human lives.The occurrence and spread of wildfires are influenced by many factors,among which climate plays an important role.The frequency of climate anomalies has increased significantly in recent decades,with wildfires increasing in size and severity in many parts of the world.Both sea surface temperature and pressure anomalies affect climate change,which in turn affects regional temperature and precipitation.Changes in regional temperature and precipitation affect the humidity and amount of combustible material,and finally affects the occurrence of wildfires.Correlation analysis,regression analysis,empirical orthogonal function analysis,singular value decomposition and other methods was used to analyze the impact of global sea surface temperature anomalies on the seasonal severity rating of fire in East Asia under each climate zone from 2000 to 2017.
