Belitung Island, situated in the Southeast Asian tin belt, experiences substantial transformations in land use and land cover (LULC) driven by mining activities, impacting both local economic growth and the ecosystem. This study aims to elucidate the dynamic LULC changes on Belitung Island and evaluate deforestation trends. LULC data spanning from 1990 to 2020 were acquired from The Indonesian Ministry of Environment and Forestry (KLHK), employing supervised classification of satellite imageries. The dataset demonstrated an overall accuracy ranging from 0.79 to 0.92 and was reclassified into six types based on the Intergovernmental Panel on Climate Change or IPCC's classes, encompassing forest, cropland, grassland, other land, settlements, and wetlands. Our research unveiled a notable reduction of over 25 % in forest cover within the past 30 years. Notably, 2020 exhibited instances of reforestation, which subsequently transformed into cropland (0.57 %), grassland (0.32 %), and other lands (0.39 %). Belitung Island grapples with challenges related to sustainable development, environmental conservation, and food security. Forest Landscape Restoration (FLR) emerges as a potential strategy to address some of the socioeconomic and ecological issues.
勿里洞岛位于东南亚锡矿带，受采矿活动影响，土地利用和土地覆盖（LULC）发生了重大变化，对当地经济增长和生态系统都产生了影响。本研究旨在阐明勿里洞岛LULC的动态变化，并评估森林砍伐趋势。从印度尼西亚环境与林业部（KLHK）获取了1990年至2020年的LULC数据，采用卫星图像监督分类法。该数据集的总体准确率在0.79至0.92之间，并根据政府间气候变化专门委员会（IPCC）的类别重新划分为六种类型，包括森林、农田、草地、其他土地、居民点和湿地。我们的研究表明，在过去30年里，森林覆盖率显著下降了25%以上。值得注意的是，2020年出现了重新造林的情况，随后这些林地转变为农田（0.57%）、草地（0.32%）和其他土地（0.39%）。勿里洞岛面临着与可持续发展、环境保护和粮食安全相关的挑战。森林景观恢复（FLR）成为解决一些社会经济和生态问题的潜在策略。
