| 摘 要： | 基于地质灾害的多样性及其变化的随机性和非稳定性特点,本文综合利用数学算法和GIS技术,设计了地质灾害预警模型,分析了诱发地质灾害的地形、地貌、气象、水文等几方面的因素,应用地质灾害显式统计预警的基本原理,并通过确定性系数模型(CF)综合分析了天津市地质灾害分布与地质环境基础因素的关系,更好的修订了我市地质灾害预警预报模型.实践证明,应用基于GIS 的地质灾害预警预报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,预警预报精度得到提高,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 features of variety and variability of geo-hazards,and using the map algebra and GIS technologies,the authors design a geo-hazard early warning model,and analyze the influence factors of geo-hazard including terrain,physiognomy,hydrology etc,and find out the relationship between the geo-hazard distribution and geo-environmental factors of Tianjin City.The warning system has been playing a considerable important action to protect life and property of human for resent years. |
