【 摘 要 】

Drought is considered a serious disaster after floods and typhoons and is tending to increase frequency and intensity due to climate change on a global scale. In addition, droughts also cause large and small fires that occur daily around the world, damaging forests and forest ecosystems and having a significant impact on the economy, society, and people. This paper presents the situation of forest fires in U Minh Ha forest of Ca Mau province, which is the southernmost province of Vietnam. The study used satellite imagery processing, which combined spatial analysis to identify areas of fire sensitivity, in the face of drought risk associated with climate change in the dry season in 2016. AHP hierarchy analysis was performed using factors such as surface temperature, leaf moisture, vegetation cover, vegetation density, the distance to water sources, the distance to residential areas, and the distance to fire protection establishments. The results show that the zone with average fire sensitivity accounted for nearly half of the forest area and is distributed in the south and southwest. The high fire sensitivity area is negligible. The study results are useful for planning strategies to protect forest resources against the drought risk caused by climate change, which is becoming increasingly harsh.
