| 中文摘要: |
| 基于内蒙古大兴安岭1990—2019年森林火灾历史档案和同期气象因子的数据，对该地区林火与气象因子间的相关性进行了研究。结果表明，林火发生与气象因子间的关系密切。林火发生次数随着温度的升高和降水的减少呈上升趋势；研究区日均相对湿度范围在58%~62%，火灾发生次数最多；林火发生次数与日照时数、日均温、日最高温间均呈显著正相关；过火面积与日均相对湿度间呈显著负相关，与日照时数间呈显著正相关。 |
| 英文摘要: |
| Based on the historical archives of forest fires and meteorological data of the same period from 1990 to 2019 in Greater Khingan Mountains of Inner Mongolia, the correlation between forest fires and meteorological factors was studied. The results showed that there was a close relationship between the occurrence of forest fire and meteorological factors.The number of forest fires increased with the increase of temperature and the decrease of precipitation; the daily average relative humidity ranged from 58% to 62%, and the fires occurred most frequently; the occurrence of forest fires was significantly positively correlated with sunshine duration, daily average temperature and daily maximum temperature; the burned area had a significant negative correlation with daily average relative humidity and a significant positive correlation with sunshine duration. |
