| 中文摘要: |
| 本研究旨在评估特定研究区域内地裂缝灾害的易发性，以识别高风险区域，从而有效地应对地裂缝对人民群众生活、生命财产安全及地方经济社会发展的危害。基于ArcGIS的空间分析技术，结合层次分析法（AHP）构建了一套全面的地裂缝易发性评价指标体系。通过该体系，利用综合评价模型进行数据的叠加分析与预测，科学划分地裂缝灾害的易发区域。研究区内共发育48条地裂缝，依据易发性评价结果，将该区细分为4个等级：高易发区（3046.58 km²，占比14.77%）、中易发区（4451.37 km²，占比21.58%）、低易发区（8215.10 km²，占比39.82%）和非易发区（4913.25 km²，占比23.82%）。这一分区结果详细揭示了地裂缝灾害在不同区域的潜在威胁程度，基于上述研究结果，提出了针对地裂缝灾害的合理化防治建议，旨在为未来地裂缝灾害的预警、防灾减灾工作提供科学依据和参考，以减轻其对当地社会经济和居民生活的负面影响。 |

| This study aims to assess the susceptibility to ground fissure hazards within a specific research area， in order to identify high-risk zones and effectively address the threats posed by ground fissures to the safety of people’s lives， property， and local socio-economic development. Using spatial analysis techniques based on ArcGIS， a comprehensive evaluation index system for ground fissure susceptibility was established in combination with the Analytic Hierarchy Process （AHP）. Through this system， data overlay analysis and prediction were conducted using a comprehensive evaluation model to scientifically delineate ground fissure hazard susceptibility zones. A total of 48 ground fissures were identified in the study area， and based on the susceptibility evaluation results， the area was classified into four levels： high susceptibility zone （3046.58 km²， accounting for 14.77%）， medium susceptibility zone （4451.37 km²， accounting for 21.58%）， low susceptibility zone （8215.10 km²， accounting for 39.82%）， and non-susceptibility zone （4913.25 km²， accounting for 23.82%）. This classification reveals the potential threat levels of ground fissure hazards across different regions. Based on these findings， rational prevention and control recommendations for ground fissure hazards are proposed， providing a scientific basis and reference for future early warning， disaster prevention， and mitigation efforts， with the goal of reducing the negative impact on local socio-economic conditions and residents’ lives. |
