| 摘 要： | 基于用R值评分方法对青海省1990～2006年以来的地震预报效能进行了评价，通过2种方法计算，结果表明，17年来青海省地震预报效能检验平均R值约为0．261。表明了地震危险区域的划分工作在这些年中取得了一定效果，研究也表明R值的高低不仅和预测手段有关，而且与年度地震活动水平有关。

| Abstract: | In this paper,we have estimated the earthquake prediction efficiency in Qinghai province from 1990 to 2006 based on R-value.Calculated by two methods,the results show that the average R-value is about 0.261.The R-value indicates that compartmentalization of the earthquake risk areas is effect in these years.Through these researches,we consider that high or low of R-value is not only influenced by the prediction method,but also influenced by the activity of the earthquake in the year. |
