| 中文摘要: |
| 基于福建省2003—2021年森林火灾历史数据,对福建省森林火灾发生情况进行分析,运用Pearson相关分析将2003—2021年福建省气象因子(年均温、年降水量、日照时数)与相应年份的森林火灾发生次数、平均火场面积和受灾森林面积进行相关性分析。结果表明,2003—2021年间福建省累计发生森林火灾4 790 次,自2012年以来福建省森林火灾发生次数总体减少,平均火场面积与平均受灾森林面积有所降低。森林火灾发生次数与年均温呈显著负相关关系,与日照时数呈
显著正相关关系,但与年降水量无线性相关性。除平均受灾森林面积和年均温之间呈显著负相关关系外,平均火场面积和受灾森林面积与气象因子间无明显相关性。 |
| 英文摘要: |
| Based on historical data of forest fires in Fujian Province from 2003 to 2021, this study analyzed
the occurrence of forest fires in the region. Using Pearson correlation analysis, the meteorological
factors (annual average temperature, annual precipitation, and sunshine duration) from 2003 to 2021 were
correlated with the corresponding annual forest fire frequency, average fire area, and affected forest area.
The results indicated that from 2003 to 2021, a total of 4790 forest fires occurred in Fujian Province. Since
2012, the number of forest fires had generally decreased, and both the average fire area and the average affected
forest area had shown a declining trend. The number of forest fires was significantly negatively correlated
with the annual average temperature and significantly positively correlated with sunshine duration, but
no linear correlation was found with annual precipitation. Except for a significant negative correlation between
the average affected forest area and the annual average temperature, no significant correlations were
observed between the average fire area or the affected forest area and the meteorological factors. |
