摘要
使用便携式GPS导航技术,建立样本数据。通过分析空间数据样本,获得库区地质灾害各诱发因子的敏感性系数,并使用GIS空间分析法开展库区地质灾害危险性预测。最后通过专家判译法,完成该区地质灾害调查。在地质资料相对匮乏的工作区,该方法能提高工作效率,节约成本,避免重复和遗漏,使成果更全面、系统和合理。
The sample data are obtained with the portable GPS navigation technology.And Sensitivity coefficients for the inducing factors at the reservoir are obtained by analyzing the data.GIS Spatial Analysis is used to predict risks of the geo-hazards at the reservoir.And the investigation is completed by Expert method finally.These methods are suitable for work areas lacking geo-data,raising work efficiency,reducing costs and avoiding duplication and omission,with more comprehensive,systematic and rational results.
