新型智慧城市建设为广州地质灾害监测提供了新机遇、新思路.笔者结合近年来地灾监测的科学研究和工程实践,从感知、调度、共治的角度浅谈对于广州地灾监测的一些思考.感知方面:广州市地貌结构复杂,北部丘陵台地作为地灾易发区,建议构建重点区域天-空-地三查体系,及时识别潜在风险源.预警调度:广州市地灾的发生与降雨有很强的时间相关性和空间耦合性,建议在广州市雨窝、降雨集中区构建精细化气象预警网格,提高监测预警精准度;针对地灾监测预警存在的重监测、轻预警现象,建议构建基于数据-知识双驱动的预警模型,实现高精度可解释的地灾预测建模;针对疑难边坡,建立专家研判系统,实现精准"把脉",精准"治疗".共建共治:加强跨部门跨层级合作,加强新建工程项目地灾评估,消减地灾存量,控制地灾增量.
Geological hazard monitoring based on the perspective of innovative smarter city:a case study of Guangzhou
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.
