Fire Heterogeneity Index (FHI) 2019/20

Remote sensing scientists from the NSW Department of Climate Change, Energy, the Environment and Water (NSW DCCEEW) Science and Insights Division have developed a new approach to mapping the landscape patterns of high severity fire, based on NSW Fire Extent and Severity Mapping (FESM). \r\n\r\nHigh severity fire impacts an ecosystem by completely scorching or consuming the canopy biomass. Such impacts can be harmful to biodiversity, although some species benefit or even depend on this level of fire impact. \r\n\r\nRecent advances in remote sensing of fire and innovative computation solutions by DCCEEW Remote Sensing Scientists offer accessibility to data on fire severity and landscape patterns of fire heterogeneity across broad regions.\r\n来自新南威尔士州气候变化、能源、环境与水利部（NSW Department of Climate Change, Energy, the Environment and Water，简称NSW DCCEEW）科学与洞察司的遥感科学家，基于新南威尔士州火灾范围与烈度制图（Fire Extent and Severity Mapping，简称FESM）数据集，开发了一种全新的高烈度火灾景观格局制图方法。 高烈度火灾会通过完全灼烧或消耗冠层生物量的方式对生态系统造成破坏。此类影响可能对生物多样性产生危害，但部分物种会从中获益，甚至依赖这类烈度的火灾扰动。 该部门遥感科学家在火灾遥感监测与创新计算方案领域取得的最新进展，使得大范围区域内的火灾烈度与火灾异质性景观格局数据的获取更为便捷。
