| 摘 要： | 以地震应变能作为响应因子，研究了1997至2007年赣粤闽交界及邻区4．0级（ML≥4．0）以上中强地震临震前的加卸载响应比（Y值）的基本变化特征，研究结果表明，80％以上的地震在临震前Y值呈现出高值异常形态。因而它可以作为此地区地震预测的一种手段。

| Abstract: | The load-unload response ratio theory （LURR） , risen up at the end of 1980s, has now become a mature and efficient method of earthquake prediction. In this paper, using the seismic strain energy as the response factor, we study the anomalous characteristics of the loadunload response ratios （Y） before moderate-strong earthquakes （ML≥4.0） from 1997 to 2007 in the adjacent area of Jiangxi, Guangdong and Fujian provinces.The result shows that for more than 80 percent cases, obvious anomalous high-value response ratios （Y） occurred. Therefore, the LURR method appears to be an effective method of earthquake prediction for this area. |
