摘    要:根据辽宁及邻区地质构造与区域地震活动特点,在震例研究和预报实践的基础上分别提炼了辽南和辽西—辽蒙交界两个区域的中强震预警判据,构建了基于时间尺度的震情预警指标模型;采用层次分析法对预警模型的各指标进行了无量纲数字化,得出了各指标的相对重要性排序,确定了各指标的具体权重;最后通过判断矩阵及矩阵运算的数学方法得出辽宁地区中强震预测预警等级。

关 键 词:辽宁  震情  层次分析  判据  预测预警  判断矩阵

Abstract:According to characteristic of geologic structure and seismic activity in Liaoning and the neighboring area,based on the earthquake cases studies and prediction works,the warning criterions of moderate-strong earthquake in the southern Liaoning province and the Liaoning-Inner Mongolia boundary region are extracted,and the earthquake early-warning model based on time-scales is constructed.All kind of indicators used in early-warning model are processed with non-dimensional method by the analytic hierarchy process.The relative order of importance and weighs of each indicator are calculated.Finally,the early-warning level of moderate-strong earthquakes in Liaoning area are obtained by judgment matrix and mathematical method for matrix operation.
Keywords:Liaoning  Seismic activity  Analytic Hierarchy Process(AHP)  Criterion  Early-warning  Judgment matrix
