Abstract:
【Objective】 Forest fires are an important form of disturbance in forest ecosystems, seriously affecting the structure and function of the forest. The Greater Khingan Range in Inner Mongolia is one of the most important forest ecosystems in China. This region has frequent forest fires, making it a suitable location for determining the temporal and spatial factors that cause fires. This study can provide a strong scientific basis for forest fire prevention and management. 【Method】 We used ArcGIS10.2 and Origin software to analyze remote sensing images and examine forest fire characteristics in Inner Mongolia from 1980 to 2015. Forest fire dynamics were assessed based on temporal and spatial factors.【Result】The temporal and spatial distribution of forest fires in Inner Mongolia showed a distinct pattern. We observed periodical patterns in annual variations in damaged forest areas with an interval of 16 years. Spring was the season with the highest occurrence of forest fires. During the time period when forest fire prevention resources were being adjusted, forest fires occurred most frequently in April and May(during the Spring Equinox, fresh green and grain rain solar terms), the main contents should be controlling the fire sources. In addition, the probability of forest fire occurrence was relatively high at the beginning of the month, so vigilance should be increased during this time. Forest fires mainly occurred from 9:00 to 17:00, primarily in areas such as Hulunbuir City, Chifeng City, Ordos City and Hinggan League. Hinggan League had the largest burned area and fire occurrence in the Greater Khingan Range forest area was more frequent than that in other regions.【Conclusion】Forest fires in Inner Mongolia are frequent and burned areas are relatively large, with frequent fires being closely related to human activities and climate characteristics. Thus, it is important to strictly control field fire sources and fire-use activities. Based on the temporal and spatial dynamic characteristics of forest fires in the Inner Mongolia Autonomous Region, we suggest that fire prevention propaganda and education should be strengthened and scientific forest fire prevention measures should be used to formulate reasonable forest protection policies.
