In the penultimate quarter of 2019, Bolivia suffered multiple forest fires in the Chiquitania and the Amazon region. According to experts and authorities, a category six wildfire, consumed at a rate of 4000 hectares per hour. Given this event, this article aims to use Landsat 8 satellite imagery to calculate the Normalized Burn Ratio (NBR), the Normalized Burn Ratio-Thermal (NBR-T), the Normalized Difference Vegetation Index (NDVI), and the Soil Adjusted Vegetation Index (SAVI) to categorize the environmental impact of the wildfires. These four indices were extracted from 22 postfire images, and it was found that the total burned area, in Beni department, that belongs to the Amazon region is 1183 134 hectares and the total burned area, in the municipalities that are inside or cross the Chiquitania is 3 825 359 hectares.

基于卫星的玻利维亚基基塔尼亚和亚马逊地区森林火灾分析：案例2019

在2019年倒数第二个季度，玻利维亚在基基塔尼亚和亚马逊地区遭受了多次森林大火。根据专家和当局的说法，六类野火的消耗量为每小时4000公顷。鉴于此事件，本文旨在使用Landsat 8卫星图像来计算归一化燃烧比（NBR），归一化燃烧比热（NBR-T），归一化植被指数（NDVI）和土壤调整植被指数（SAVI）对野火的环境影响进行分类。这四个指标是从22张火灾后的图像中提取的，发现属于亚马逊地区的贝尼省的总燃烧面积为1183 134公顷，而在基基塔尼亚内部或交叉的自治市中的总燃烧面积是3 825 359公顷。
