由于森林砍伐等环境影响,森林迅速减少,全球变暖,森林火灾等自然灾害以及各种人类活动日益引起人们的关注。森林火灾的频率和严重程度越来越高,对生态系统造成了重大损害,经济,野生动物,和人类安全。在干燥和炎热的季节,森林火灾的可能性也增加了。准确监测和分析森林覆盖的大规模变化对于确保可持续森林管理至关重要。遥感技术有助于随着时间的推移,精确研究大面积森林覆盖的这种变化。这项研究分析了森林火灾随时间的影响,识别热点,并探讨了影响森林覆盖变化的环境因素。Sentinel-2图像用于研究文莱达鲁萨兰国从2017年到2022年的五年森林覆盖面积的变化。基于对象的方法,简单非迭代聚类(SNIC)用于使用NDVI值对区域进行聚类,并分析每个聚类的变化。结果表明,发生火灾的集群面积减少,降水减少。在2017年至2022年之间,森林火灾的增加和降水量的减少导致了集群区域的变化如下:66.11%,69.46%,68.32%,73.88%,77.27%,78.70%,分别。此外,在Belait地区确定了每年响应森林火灾的热点地区。这项研究将帮助森林管理者评估森林覆盖损失的原因,并制定保护和造林策略。
The rapid reduction of forests due to environmental impacts such as deforestation, global warming, natural disasters such as forest fires as well as various human activities is an escalating concern. The increasing frequency and severity of forest fires are causing significant harm to the ecosystem, economy, wildlife, and human safety. During dry and hot seasons, the likelihood of forest fires also increases. It is crucial to accurately monitor and analyze the large-scale changes in the forest cover to ensure sustainable forest management. Remote sensing technology helps to precisely study such changes in forest cover over a wide area over time. This research analyzes the impact of forest fires over time, identifies hotspots, and explores the environmental factors that affect forest cover change. Sentinel-2 imagery was utilized to study changes in Brunei Darussalam\'s forest cover area over five years from 2017 to 2022. An object-based approach, Simple Non-Iterative Clustering (SNIC), is employed to cluster the region using NDVI values and analyze the changes per cluster. The results indicate that the area of the clusters reduced where fire incidence occurred as well as the precipitation dropped. Between 2017 and 2022, the increased forest fires and decreased precipitation levels resulted in the change in cluster areas as follows: 66.11%, 69.46%, 68.32%, 73.88%, 77.27%, and 78.70%, respectively. Additionally, hotspots in response to forest fires each year were identified in the Belait district. This study will help forest managers assess the causes of forest cover loss and develop conservation and afforestation strategies.
