Study on the evaluation of ground fissure susceptibility and prevention measures in the northern plain of Henan Province
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.
