| 摘 要： | 用单键群分析方法，研究了甘肃及邻区发生的几次中强地震前的空间相关长度增长的现象. 结合震源区不同的情况，分别选取了圆形和沿断层带分布的平行四边形空间窗. 结果表明，所研究的几次中强地震前都观察到相关长度增长的现象.

| Abstract: | The growing correlation length prior to the moderate-great earthquakes occurred in Gansu Province and its nearby area since 1986 has been studied using the method of single-link cluster analysis (SLC). According to different conditions in the source area, the circular spatial window centered in the epicenter and the parallelogrammic spatial window along the fault belt have been selected. The results show that the phenomena of growing correlation length have been observed before the earthquakes studied in the paper. |
