融合多源特征的轻量化深度学习跨场景滑坡智能识别
Lightweight Deep Learning for Cross⁃Scene Landslide Intelligent Recognition with Multi⁃Source Feature Fusion

极端环境因素影响下诱发的区域性滑坡对生命财产安全构成严重威胁. 因此,推进区域性滑坡识别的自动化,提升复杂地形下隐患区域的信息透明度,对地质灾害数据库建设和风险管理至关重要. 深度学习方法提供了有效的解决方案,克服了传统方法自动化程度不足的问题. 然而,现有研究多侧重于模型结构优化与训练策略改进,在多源地形数据的有效融合与跨区域识别能力提升方面仍存在挑战. 针对上述瓶颈,提出了一种具有跨区域识别能力的深度学习ResU⁃CBNet模型. 该模型将空间和通道混合的注意力机制融入神经网络模型,并采用残差网络替换原有普通网络结构. 模型在多尺度特征融合条件下的性能显著优于单一遥感数据,具体表现为PA、CPA、F1_Score、MIoU分别提升2.1%、2.6%、6.9%、2.9%;同时,模型在不同场景、不同光谱波段和空间分布的区域中验证了其跨场景泛化能力,PA和F1_Score分别达到了92.8%、91.3%和83.2%、80.0%的性能,识别效果与实际区域高度吻合.提出的跨场景的识别方法可为滑坡智能识别和风险评估提供一定的参考.
Regional⁃scale landslides triggered by extreme environmental factors pose a significant threat to life and property safety. Consequently, advancing the automation of regional landslide identification and enhancing the information transparency of potential hazard zones in complex terrain are paramount for the construction of geological hazard databases and effective risk management.Deep learning methods provide an effective solution, overcoming the problem of insufficient automation in traditional methods. However, existing research primarily focuses on optimizing model architecture and improving training strategies, leaving challenges in the effective fusion of multi⁃source topographic data and the enhancement of cross⁃regional identification capability. To address these bottlenecks, this paper proposes ResU⁃CBNet, a deep learning model with robust cross⁃regional identification capability. The model integrates a hybrid spatial and channel attention mechanism into the neural network and utilizes a residual network to replace the conventional network structure. The model’s performance under multi⁃scale feature fusion conditions significantly outperforms that of single remote sensing data, specifically showing improvements of 2.1% in PA, 2.6% in CPA, 6.9% in F1_Score, and 2.9% in MIoU.Furthermore, the model validates its cross⁃scene generalization capability across regions with different scenarios, spectral bands, and spatial distributions, achieving PA and F1_Score performances of 92.8%, 91.3% and 83.2%, 80.0%, respectively. The identification results demonstrate a high degree of consistency with the actual regions.The cross⁃scene identification method presented here offers a valuable reference for intelligent landslide recognition and risk assessment.
