This study focuses on the northern scenic area of Changbai Mountain, aiming to evaluate the emergency evacuation capacity of the region in the context of geological disasters and to formulate corresponding improvement strategies. Due to the relatively small area of this region, difficulties in data acquisition, and insufficient precision, traditional models for evaluating emergency evacuation capacity are typically applied to urban built environments, with relatively few studies addressing scenic areas. To tackle these issues, this research employs the Real-Enhanced Super-Resolution Generative Adversarial Network (Real-ESRGAN), which successfully resolves the problem of blurriness in remote sensing images and significantly enhances image clarity. Coupled with the Graph Convolutional Network (GCN) model, the study calculates the emergency evacuation time for each raster point, providing a comprehensive assessment of the region's evacuation capacity. Based on the evaluation results, the study proposes targeted improvement measures for areas identified as having poor emergency evacuation capacity, taking into account the existing infrastructure of the scenic area. By constructing an indicator system encompassing effectiveness, accessibility, and safety, the feasibility of each proposed enhancement strategy is assessed scientifically and rationally. Through these integrated tools and methodologies, this research significantly improves the accuracy of data processing, evaluation, and decision support, showcasing a comprehensive approach to scenic area research that provides critical support for geological disaster management, emergency planning, and the overall safety of the Changbai Mountain scenic area.
本研究聚焦于长白山北景区,旨在评估该地区在地质灾害背景下的应急疏散能力,并制定相应的改进策略。由于该地区面积相对较小,数据获取困难且精度不足,传统的应急疏散能力评估模型通常应用于城市建成环境,针对景区的研究相对较少。为解决这些问题,本研究采用了真实增强超分辨率生成对抗网络(Real-ESRGAN),成功解决了遥感图像模糊问题并显著提高了图像清晰度。结合图卷积网络(GCN)模型,该研究计算了每个栅格点的应急疏散时间,对该地区的疏散能力进行了全面评估。基于评估结果,该研究针对被认定为应急疏散能力较差的区域提出了有针对性的改进措施,同时考虑了景区现有的基础设施。通过构建一个涵盖有效性、可达性和安全性的指标体系,对每个提出的增强策略的可行性进行了科学合理的评估。通过这些综合工具和方法,本研究显著提高了数据处理、评估和决策支持的准确性,展示了一种全面的景区研究方法,为地质灾害管理、应急预案制定以及长白山景区的整体安全提供了关键支持。
