摘要

森林火灾是一个紧迫的全球性问题,对人类生活和环境有着深远的影响,而气候变化又加剧了森林火灾的频率和强度。目前迫切需要先进的预测系统来减轻这些影响。为了解决这个问题,本研究引入了一个整合了无线传感器网络(WSN)、数据分析和机器学习的森林火灾预测框架。部署在林区的传感器节点收集实时气象数据,并使用 LoRaWAN 技术进行传输。数据挖掘技术利用 SVM 算法对数据进行分析,揭示气象参数与野火风险之间的关系。SVM 模型根据温度、湿度、风速和降雨量数据对森林火灾风险等级进行分类的准确率高达 86%。WSN 和 SVM 算法的集成框架为森林火灾风险预测提供了一个高准确度模型。该模型与加拿大森林火灾危险等级系统进行了比较,以验证其准确性,结果表明与历史记录和报告非常吻合。该模型的实际意义包括高效管理、早期检测和预防策略。不过,该模型的局限性也为今后的研究提出了建议,我们应考虑更广泛的地理应用,并使用先进的机器学习方法来增强模型的预测能力。

Advancing Forest-Fire Management: Exploring Sensor Networks, Data Mining Techniques, and SVM Algorithm for Prediction
Forest-fire is a pressing global problem that has far-reaching effects on human life and the environment, with climate change exacerbating their frequency and intensity. There is an urgent need for advanced predictive systems to mitigate these impacts. To address this issue, this study introduces a forest-fire prediction framework integrating wireless sensor networks (WSNs), data analysis, and machine learning. Sensor nodes deployed in a forest area collected real-time meteorological data, which was transmitted using LoRaWAN technology. Data mining techniques prepared the data for analysis using the SVM algorithm, revealing relationships between meteorological parameters and wildfire risk. The SVM model demonstrated an accuracy of 86% in classifying forest-fire risk levels based on temperature, humidity, wind speed, and rainfall data. The integrated framework of WSNs and the SVM algorithm provides a high-accuracy model for forest-fire risk prediction. The model is compared to the Canadian Forest Fire Hazard Rating System to validate its accuracy, demonstrating strong agreement with historical records and reports. The model's practical implications include efficient management, early detection, and prevention strategies. However, the model's limitations suggest avenues for future research, we should consider broader geographic applications and using advanced machine-learning methods to enhance the model's predictive capabilities.
