Abstract: In order to overcome the problems of low monitoring accuracy and efficiency in the current risk information monitoring methods, this paper proposes a spatial analysis based monitoring method for geographical risk information in sensitive areas. Firstly, this method constructs a real-time monitoring platform with monitoring terminal, information data collection, real-time monitoring and analysis, and designs and analyses the functional modules. Using spatial analysis technology and target location, the real-time collection of hazard information data and target centroid location are carried out. C/S model is used to manage the geohazard information data in sensitive areas. The concept of E-R chart is used to build a database, which provides data support for the monitoring process. The experimental results show that the accuracy and efficiency of the proposed method are high, and the highest monitoring accuracy is 98.7%.
