Wildfire Vulnerability Assessment in Western Sichuan China Based on Multi-Source Spatiotemporal Data

The consideration of fire vulnerability (potential effects of fire on social and ecological values) should always be part of fire risk evaluations. This study aimed to map the fire vulnerability based on six factors, including per capita GDP, population density, housing price, star rating and the number of tourist attractions, land use status, and available fire risk index from previous studies. The analytic hierarchy process was used to analyze the fire vulnerability in three prefectures in western Sichuan (Liangshan Prefecture, Ganzi Prefecture, and Aba Prefecture). The wildfire vulnerability assessment showed strong consistency with real cases. The results provided a scientific basis for the investment in forest fire prevention and the deployment of forest fire prevention teams.
