Abstract: The construction of the innovative smarter city provides new opportunities and new ideas for the geological disaster monitoring in Guangzhou. Combining the scientific research and engineering practice of the geological disaster monitoring in recent years, the author briefly discusses some thoughts on the geological disaster monitoring in Guangzhou from the perspectives of perception, dispatch and co-governance. In terms of perception: the geomorphic structure of Guangzhou is complex, and the northern hilly platform is a disaster-prone area. It is suggested to construct a three-inspection system of sky-air-ground in key areas to identify potential risk sources in time. Early warning and dispatching: The occurrence of ground disasters in Guangzhou has a strong temporal correlation and spatial coupling with rainfall. It is suggested to construct a refined meteorological early warning grid in the rain nest and rainfall concentration area to improve the accuracy of monitoring and early warning; In view of the phenomenon of heavy monitoring and light warning in geological disaster monitoring and warning, it is suggested to build a data-knowledge-driven early warning model to achieve high-precision and interpretable disaster prediction modeling; For the difficult slope, an expert research and judgment system should be established to achieve accurate "pulse" and accurate "treatment". Joint construction and governance: strengthen cross-departmental and cross-level cooperation, strengthen the assessment of new construction projects, reduce the stock of local disasters, and control the increase of local disasters.
