以粤东山区梅州市石灰岩矿山分布区域为研究对象，采用信息量法和GIS技术对矿山岩溶地面塌陷灾害进行危险性评价。选取岩性、地下水动力条件、地壳稳定性、第四系厚度、地下活动强度（与矿井距离）等指标构建岩溶地面塌陷危险性评价体系，并结合GIS技术进行空间数据采集、管理和分析，将梅州市岩溶地面塌陷风险划分为不稳定、较稳定和稳定3个等级，其中稳定区域的分布范围最广，主要位于基岩裸露的低山与丘陵地带。研究成果可为城市地质安全评估与预测以及灾害防治策略的制定提供理论支撑。

Taking the distribution of limestone mines in Meizhou, a mountainous area in eastern Guangdong Province as the research objects, we used information quantity method and GIS technology to assess the risk of Karst ground collapse disasters. We selected the lithology, groundwater dynamic, crustal stability, Quaternary thickness, and underground activity intensity(distance to mine shaft) to construct risk assessment system for Karst ground collapse, and used GIS technology to conduct spatial data collection, management, and analysis. Consequently, we classified the Karst ground collapse risk in Meizhou into unstable, relatively stable, and stable three levels. The stable zones, which cover the widest distribution,are primarily located in low hills and hilly regions with exposed bedrock. The research findings provide theoretical support for urban geological safety assessment and prediction, as well as the formulation of disaster prevention strategies.
