摘要
信息量法是滑坡灾害危险性分析方法之一，通过对区域已知滑坡体特征的分类提取，确定影响因素，按照信息量公式建立信息量模型，进而应用GIS技术实现整个区域的滑坡危险性分区。分选出稳定区、低危险区、中危险区、高危险区四个级别的区划，为库区工程安全、环境保护和防灾减灾提供指导。
The information content method is one of the landslide disaster risk analysis, which determines the influencing factor through the classified extraction of known region landside mass characteristic, establishes the information content model according to the information content formula, and then forms the entire region landslide risk zone by using GIS technology. The zone is divided into 4 grades of stable, low - risk, middle - risk, and high - risk regions, which provides a guidance for the project security, environmental protection, disaster prevention, and disaster reduction in reservoir areas.
