区域地质灾害趋势预测理论与方法

THEORY AND METHOD FOR PREDICTION OF REGIONAL GEO-HAZARDS

摘要: 区域地质灾害趋势预测对于国家土地资源的合理开发利用和制定减灾防治对策具有重要意义。本文总结了区域地质灾害三个层次评估的理论与方法, 即基于自然属性的地质灾害研究、基于风险分析的地质灾害研究和基于信息-决策支持系统的地质灾害研究。作者认为, 运用GIS技术, 将这三层次的评价方法结合起来, 是进行区域地质灾害趋势预测的有效途径。本文最后介绍了1∶600万全国地质灾害趋势预测图编制的思路与成果。

Abstract: The three-level theory and method based on the nature,risk and information-decision support system are applied to prediction of regional geologic hazords. GIS is a powerful tool in combination with three-level data to outline the regional geologic hazard features.At last,a Map of the predicted main geologic hazards in China (1:6000000)is presented.
