摘要
利用河北省近40a的地质灾害发生个例资料,分析了地质灾害时空分布特征;进行预报分区,分别找出了各区泥石流临界雨量指标;采用数学决策模型-权重分布集成法,对未来24h降水预报产品、中央台下发的降水指导预报产品、河北省气象台MM5模式降水预报产品、河北省气象台下发的降水指导预报产品等进行降水集成,将各区的降水集成结果及前期降雨量分别与临界雨量指标进行比较,作出地质灾害预报。
The distribution of geohazard of Hebei Province was analysised using the data of past 40 years. Then geohazard mapping was done, critical rainfall values for debris flow of different areas were proposed. According the mathmatical decision making and weight method, geohazard forecasting was done using the rainfall forecasting data.
