| 摘 要： | 根据天津市地质灾害特点及与气象条件的关系,从气象因素和地质灾害隐患入手,深化研究地质环境和降水因素与地质灾害发生的关系,综合利用数学算法和GIS技术,建立了天津市地质灾害气象预警模型和预警系统。此外,重点介绍了五名山东滑坡自动化远程监测系统示范工程,运行结果显示,监测系统的实施保证了监测数据的连续性,可以较好的反应滑坡的变形特征及变形趋势。实践证明,应用基于GIS 的地质灾害预警系统已在我市近几年的地质灾害气象预警预报中不断完善,预警精度得到提高,防灾减灾效果明显,对保护人民生命财产安全发挥了重要作用。

| Abstract: | Based on the characteristics of geological hazards and its relation with meteorological condition in Tianjin city, the relation of precipitation and geological environment with geological hazards is studied in the light of meteorological factors and potential geological hazards. Useing the map algebra and GIS technologies, the geological hazard meteorological alarming model and system of Tianjin is established. Besides, this paper fo-cuses on a demonstrative automatic landslide monitoring system in east of Wumingshan area. Operation result shows that the real-time observation system guarantees the monitoring data continuity. There is a good reflection of landslide distortion characteristic and the distortion tendency. Practice proves that, basing on GIS, the warning and predicting system of geological hazard has became more perfect in recent application. It’s precision was im-proved yet and gets an obvious effect in disaster prevention and reduction. The system is playing a considerable important action to protect life and property of human. |
