This paper examines spatial and temporal patterns of large to medium‐sized fires across the Indonesian Archipelago using remote sensing, particularly the MODIS fire products, over a 14 years period (2000–13 inclusive) in conjunction with climatic and land data in a GIS. Results showed fires (burned area and number of fires) were detected the most in year 2002 and least in 2010. The extent of burning was correlated with the annual Southern Oscillation Index with most burning occurring during times of sustained negative SOI values, which generally means drier conditions across the region. Most of the detected fires occurred in the middle of the dry season and in drier eastern Indonesia. Across Indonesia, approximately 1.5 per cent of available open vegetation area burned, whereas only 0.5 per cent of forest area burned. Most open vegetation burning was detected in the savanna with an area equivalent to 11.1 per cent of its extent being burned over the 14 years. On Sumba Island, where the pronounced dry season extends for at least four months, open vegetation is the most common land cover type, of which 99 per cent burned by area over the study period making it the island with the most burned areas in the Indonesian Archipelago.

印度尼西亚热带稀树草原火灾的时空格局

本文结合GIS中的气候和土地数据，使用遥感技术（尤其是MODIS消防产品），在14年（含2000-13年）的时间范围内，研究了印尼群岛内大中型火灾的时空格局。结果表明，在2002年和2010年检测到的火灾次数最多（燃烧面积和火灾次数）。燃烧程度与年度南方涛动指数相关，其中大多数燃烧发生在SOI持续为负值的时候。整个地区的天气更干燥。大部分火灾是在旱季中旬和印度尼西亚东部较干燥的地方发生的。在整个印度尼西亚，大约有1.5％的可用开放植被面积被燃烧，而只有0.5％的森林面积被燃烧。在大草原上发现了大部分开放的植被燃烧，其面积相当于过去14年燃烧面积的11.1％。在Sumba岛上，干旱季节至少持续了四个月，其中开放的植被是最常见的土地覆盖类型，在研究期间，其中99％的土地被烧成面积，使该岛成为印度尼西亚最烧毁的区域。群岛。
