Under the background of global climate change, human activities have intensified the occurrence of extreme climate events, increased the possibility of grassland fire, and seriously threatened these curity of terrestrial ecosystem and people’s life and property. The Hulunbuir grassland as a border zone of China, Mongolia, and Russia, so the study of spatial and temporal distribution pattern and influencing factors of grassland fire is of great significance to the management and prevention and control of grassland fire in our country. In this study, Fire_CCI51 was used as the main data source, and GIS spatial analysis technology was applied to explore the spatial and temporal distribution of grassland fires in Hulunbuir region from 2001 to 2019. The results show that there has the randomness of large interannual fluctuations and indefinite cycles and the regularity of bimodal concentration in spring and autumn; the spatial distribution is concentrated in the eastern forests and grasslands and near the border line , shows a pattern of more east and less west, more north and less south. In order to explore the influence of meteorological factors on grassland fire in HulunBuir grassland, this study conducted an in-depth analysis of relationship between major meteorological factors and grassland fires by using correlation analysis method. It was found that there was no significant correlation. Therefore, this paper makes a statistical analysis of the causes of grassland fires, and finds that human activities are the main cause of grassland fires. In addition, the spatial analysis is used to extract the burn area in boder area and buffer zone, and found that there are far more fires outside than inside and Russia has far more fires than Mongolia or China. In view of junction environment is not very different, this study conducts a comparative analysis of the different grassland management and prevention and control policies in China, Mongolia and Russia, and finds that China’s policy is more strict and perfect, and has more advantages in border fire prevention and control. Therefore, the study believes that the local government should urge herdsmen to mow the grassland in time, focus on human activities in pastoral areas, and strictly manage anthropogenic fire sources, rationally allocate prevention and control forces, focusing on forest-steppe zone and border zone. At the same time, China’s prevention and control experience should also be shared with neighboring countries to promote joint prevention and control in border areas.

Key words: grassland fire, border fire, grassland fire prevention and control policy, Hulunbuir Grassland
